2016-02-22ARM: 8532/1: uncompress: mark putc as inlineArnd Bergmann
When CONFIG_DEBUG_ICEDCC is set, we don't use the platform specific putc() function, but use icedcc_putc() instead, so putc is unused and causes a compile time warning: In file included from ../arch/arm/boot/compressed/misc.c:28:0: arch/arm/mach-rpc/include/mach/uncompress.h:79:13: warning: 'putc' defined but not used [-Wunused-function] arch/arm/mach-w90x900/include/mach/uncompress.h:30:13: warning: 'putc' defined but not used [-Wunused-function] On most platforms, this does not happen, because putc is defined as 'static inline' so the compiler will automatically drop it when it's unused.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC multiplatform code updates from Arnd Bergmann: "This branch is the culmination of 5 years of effort to bring the ARMv6 and ARMv7 platforms together such that they can all be enabled and boot the same kernel. It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts. Linus Walleij also has some patchs to clean up the older ARM Realview platforms by finally introducing DT support, and Rob Herring has some for ARM Versatile which is now DT-only.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "Here is the bulk of GPIO changes for v4.5. Notably there are big refactorings mostly by myself, aimed at getting the gpio_chip into a shape that makes me believe I can proceed to preserve state for a proper userspace ABI (character device) that has already been proposed once, but resulted in the feedback that I need to go back and restructure stuff. So I've been restructuring stuff. On the way I ran into brokenness (return code from the get_value() callback) and had to fix it. Also, refactored generic GPIO to be simpler. Some of that is still waiting to trickle down from the subsystems all over the kernel that provide random gpio_chips, I've touched every single GPIO driver in the kernel now, oh man I didn't know I was responsible for so much... Apart from that we're churning along as usual. I took some effort to test and retest so it should merge nicely and we shook out a couple of bugs in -next. Infrastructural changes: - In struct gpio_chip, rename the .dev node to .parent to better reflect the fact that this is not the GPIO struct device abstraction. We will add that soon so this would be totallt confusing. - It was noted that the driver .get_value() callbacks was sometimes reporting negative -ERR values to the gpiolib core, expecting them to be propagated to consumer gpiod_get_value() and gpio_get_value() calls. This was not happening, so as there was a mess of drivers returning negative errors and some returning "anything else than zero" to indicate that a line was active. As some would have bit 31 set to indicate "line active" it clashed with negative error codes. This is fixed by the largeish series clamping values in all drivers with !!value to [0,1] and then augmenting the code to propagate error codes to consumers. (Includes some ACKed patches in other subsystems.) - Add a void *data pointer to struct gpio_chip. The container_of() design pattern is indeed very nice, but we want to reform the struct gpio_chip to be a non-volative, stateless business, and keep states internal to the gpiolib to be able to hold on to the state when adding a proper userspace ABI (character device) further down the road. To achieve this, drivers need a handle at the internal state that is not dependent on their struct gpio_chip() so we add gpiochip_add_data() and gpiochip_get_data() following the pattern of many other subsystems. All the "use gpiochip data pointer" patches transforms drivers to this scheme. - The Generic GPIO chip header has been merged into the general <linux/gpio/driver.h> header, and the custom header for that removed. Instead of having a separate mm_gpio_chip struct for these generic drivers, merge that into struct gpio_chip, simplifying the code and removing the need for separate and confusing includes. Misc improvements: - Stabilize the way GPIOs are looked up from the ACPI legacy specification. - Incremental driver features for PXA, PCA953X, Lantiq (patches from the OpenWRT community), RCAR, Zynq, PL061, 104-idi-48 New drivers: - Add a GPIO chip to the ALSA SoC AC97 driver. - Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir, but the branch is merged here too to account for infrastructural changes). - The sx150x driver now supports the sx1502" * tag 'gpio-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (220 commits) gpio: generic: make bgpio_pdata always visible gpiolib: fix chip order in gpio list gpio: mpc8xxx: Do not use gpiochip_get_data() in mpc8xxx_gpio_save_regs() gpio: mm-lantiq: Do not use gpiochip_get_data() in ltq_mm_save_regs() gpio: brcmstb: Allow building driver for BMIPS_GENERIC gpio: brcmstb: Set endian flags for big-endian MIPS gpio: moxart: fix build regression gpio: xilinx: Do not use gpiochip_get_data() in xgpio_save_regs() leds: pca9532: use gpiochip data pointer leds: tca6507: use gpiochip data pointer hid: cp2112: use gpiochip data pointer bcma: gpio: use gpiochip data pointer avr32: gpio: use gpiochip data pointer video: fbdev: via: use gpiochip data pointer gpio: pch: Optimize pch_gpio_get() Revert "pinctrl: lantiq: Implement gpio_chip.to_irq" pinctrl: nsp-gpio: use gpiochip data pointer pinctrl: vt8500-wmt: use gpiochip data pointer pinctrl: exynos5440: use gpiochip data pointer pinctrl: at91-pio4: use gpiochip data pointer ...

Pull MTD updates from Brian Norris: "Generic MTD: - populate the MTD device 'of_node' field (and get a proper 'of_node' symlink in sysfs) This yielded some new helper functions, and changes across a variety of drivers - partitioning cleanups, to prepare for better device-tree based partitioning in the future Eliminate a lot of boilerplate for drivers that want to use OF-based partition parsing The DT bindings for this didn't settle yet, so most non-cleanup portions are deferred for a future release NAND: - embed a struct mtd_info inside struct nand_chip This is really long overdue; too many drivers have to do the same silly boilerplate to allocate and link up two "independent" structs, when in fact, everyone is assuming there is an exact 1:1 relationship between a NAND chips struct and its underlying MTD. This aids improved helpers and should make certain abstractions easier in the future. Also causes a lot of churn, helped along by some automated code transformations - add more core support for detecting (and "correcting") bitflips in erased pages; requires opt-in by drivers, but at least we kill a few bad implementations and hopefully stave off future ones - pxa3xx_nand: cleanups, a few fixes, and PM improvements - new JZ4780 NAND driver SPI NOR: - provide default erase function, for controllers that just want to send the SECTOR_ERASE command directly - fix some module auto-loading issues with device tree ("jedec,spi-nor") - error handling fixes - new Mediatek QSPI flash driver Other: - cfi: force valid geometry Kconfig (finally!)

2016-01-05gpio: generic: factor into gpio_chip structLinus Walleij
The separate struct bgpio_chip has been a pain to handle, both by being confusingly similar in name to struct gpio_chip and for being contained inside a struct so that struct gpio_chip is contained in a struct contained in a struct, making several steps of dereferencing necessary. Make things simpler: include the fields directly into <linux/gpio/driver.h>, #ifdef:ed for CONFIG_GENERIC_GPIO, and get rid of the <linux/basic_mmio_gpio.h> altogether. Prefix some of the member variables with bgpio_* and add proper kerneldoc while we're at it. Modify all users to handle the change and use a struct gpio_chip directly. And while we're at it: replace all container_of() dereferencing by gpiochip_get_data() and registering the gpio_chip with gpiochip_add_data().

2015-07-28ARM: kill off set_irq_flags usageRob Herring
set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

Pull clkdev updates from Russell King: "This series addresses some breakage in clkdev caused by a previous patch set from the clk tree which introduced per-user clk structures. This basically renamed the existing 'struct clk' to 'struct clk_hw', and introduced a new 'struct clk'. This change will break anyone using clk_add_alias() with the common clk code enabled. Thankfully, the intersection of users of clk_add_alias() and those using the common clk code is practically zero, but this is something which should be fixed to keep the code sane. The problem is that clk_add_alias() does this: r = clk_get(...); l = clkdev_alloc(r, ...); clk_put(...); which causes the alias to store a pointer to 'r', which has been freed. The original patch set tried to work around this problem incorrectly - at clk_get() time, it tried to convert the struct clk to a struct clk_hw, and then creating a new struct clk from that. Clearly, if the original struct clk has been freed, then we have a use-after-free bug. We have other places in the tree which do something similar, so this series also addresses those locations too. This series addresses this problem by converting clkdev to store and use the clk_hw pointer. This allows clk_get() to only have to create it's per-user struct clk from the clk_hw. We can also get to the desired clk_hw at clk_add_alias() or clk lookup creation time, when the struct clk is "alive". We also perform some cleanups of the code: - replacing looped calls to clkdev_add() with clkdev_add_table() - replacing open-coded lookup allocation (which should have been using clkdev_alloc()) and subsequent clkdev_add() with clkdev_create() - replacing open-coded clk_add_alias() with clk_add_alias()" * 'for-linus-clk' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: clk: s2mps11: use clkdev_create() ASoC: migor: use clkdev_create() ARM: omap2: use clkdev_add_alias() ARM: omap2: use clkdev_create() ARM: orion: use clkdev_create() ARM: lpc32xx: convert to use clkdev_add_table() SH: use clkdev_add_table() clkdev: add clkdev_create() helper clkdev: const-ify connection id to clk_add_alias() clkdev: get rid of redundant clk_add_alias() prototype in linux/clk.h clkdev: drop __init from clkdev_add_table() clk: update clk API documentation to clarify clk_round_rate() clkdev: use clk_hw internally

2015-05-21ARM: OMAP1: Fix randconfig builds if ARCH_OMAP15XX not selectedTony Lindgren
With the omap1 SPARSE_IRQ changes mach/irqs.h is no longer automatically included. Turns out now we rely on ARCH_OMAP15XX including hardware.h from memory.h, so without ARCH_OMAP15XX we get build failures. As we have legacy drivers still relying on these indirect includes, let's not add more mach includes to the drivers. Those have to be removed anyways for multiplatform support. Let's fix up mach-omap1 to include soc.h where cpu_is_omap checks are done, and common.h for board-*.c files. But let's keep the indirect memory.h include for now to avoid unnecessary churn in the drivers. Signed-off-by: Tony Lindgren <tony@atomide.com>
2015-05-20ARM: OMAP1: Change interrupt numbering for sparse IRQTony Lindgren
Change interrupt numbering for sparse IRQ. We do this using a fixed offset until we can drop irqs.h once all it's users have been updated. Note that this depends on the GPIO fix for the MPUIO IRQs "gpio: omap: Fix regression for MPUIO interrupts".

2015-01-21ARM: 8271/1: omap1: Migrate debug_ll macros to use 8250.SDaniel Thompson
The omap1's debug-macro.S is similar to the generic 8250 code. Compared to the 8520 code the omap1 macro automatically determines what UART to use based on breadcrumbs left by the bootloader and automatically copes with the eccentric register layout on OMAP7XX. This patch drops both these features and relies instead on the generic 8250 macros: 1. Dropping support for the bootloader breadcrumbs is identical to the way the migration was handled for OMAP2 (see 808b7e07464d...). 2. Support for OMAP7XX still exists but it must be configured by hand (DEBUG_OMAP7XXUART1/2/3) rather than handled at runtime.

2014-07-29ARM: 8113/1: remove remaining definitions of PLAT_PHYS_OFFSET from ↵Uwe Kleine-König
<mach/memory.h> The platforms selecting NEED_MACH_MEMORY_H defined the start address of their physical memory in the respective <mach/memory.h>. With ARM_PATCH_PHYS_VIRT=y (which is quite common today) this is useless though because the definition isn't used but determined dynamically. So remove the definitions from all <mach/memory.h> and provide the Kconfig symbol PHYS_OFFSET with the respective defaults in case ARM_PATCH_PHYS_VIRT isn't enabled. This allows to drop the dependency of PHYS_OFFSET on !NEED_MACH_MEMORY_H which prevents compiling an integrator nommu-kernel. (CONFIG_PAGE_OFFSET which has "default PHYS_OFFSET if !MMU" expanded to "0x" because CONFIG_PHYS_OFFSET doesn't exist as INTEGRATOR selects NEED_MACH_MEMORY_H.)
