2014-10-20ARM: pxa: fix hang on startup with DEBUG_LLRobert Jarzmik
The commit 2111667b4677 ("ARM: pxa: call debug_ll_io_init for earlyprintk") triggers in the current kernel the attached backtrace on PXA/tosa early in the boot time when DEBUG_LL is enabled. It is due to overlap between uart virtual memory defined in DEBUG_UART_VIRT and mapped by debug_ll_io_init() and peripheral bus mapped by pxa_map_io at the same address, 0xf2100000. As hinted by Arnd, map early virtual memory for low level debug on address 0xf6200000, even if that means 2 virtual mappings will give access to the pxa internal UARTs (FFUART, BTUART, STUART, ...). ------------[ cut here ]------------ kernel BUG at /home/lumag/linux/mm/vmalloc.c:1143!

git://git.linaro.org/people/mike.turquette/linux Pull clock tree updates from Mike Turquette: "The clk tree changes for 3.18 are dominated by clock drivers. Mostly fixes and enhancements to existing drivers as well as new drivers. This tag contains a bit more arch code than I usually take due to some OMAP2+ changes. Additionally it contains the restart notifier handlers which are merged as a dependency into several trees. The PXA changes are the only messy part. Due to having a stable tree I had to revert one patch and follow up with one more fix near the tip of this tag. Some dead code is introduced but it will soon become live code after 3.18-rc1 is released as the rest of the PXA family is converted over to the common clock framework. Another trend in this tag is that multiple vendors have started to push the complexity of changing their CPU frequency into the clock driver, whereas this used to be done in CPUfreq drivers. Changes to the clk core include a generic gpio-clock type and a clk_set_phase() function added to the top-level clk.h api. Due to some confusion on the fbdev mailing list the kernel boot parameters documentation was updated to further explain the clk_ignore_unused parameter, which is often required by users of the simplefb driver. Finally some fixes to the locking around the clock debugfs stuff was done to prevent deadlocks when interacting with other subsystems." * tag 'clk-for-linus-3.18' of git://git.linaro.org/people/mike.turquette/linux: (99 commits) clk: pxa clocks build system fix Revert "arm: pxa: Transition pxa27x to clk framework" clk: samsung: register restart handlers for s3c2412 and s3c2443 clk: rockchip: add restart handler clk: rockchip: rk3288: i2s_frac adds flag to set parent's rate doc/kernel-parameters.txt: clarify clk_ignore_unused arm: pxa: Transition pxa27x to clk framework dts: add devicetree bindings for pxa27x clocks clk: add pxa27x clock drivers arm: pxa: add clock pll selection bits clk: dts: document pxa clock binding clk: add pxa clocks infrastructure clk: gpio-gate: Ensure gpiod_ APIs are prototyped clk: ti: dra7-atl-clock: Mark the device as pm_runtime_irq_safe clk: ti: LLVMLinux: Move __init outside of type definition clk: ti: consider the fact that of_clk_get() might return an error clk: ti: dra7-atl-clock: fix a memory leak clk: ti: change clock init to use generic of_clk_init clk: hix5hd2: add I2C clocks clk: hix5hd2: add watchdog0 clocks ...
2014-10-14ARM: replace strnicmp with strncasecmpRasmus Villemoes
The kernel used to contain two functions for length-delimited, case-insensitive string comparison, strnicmp with correct semantics and a slightly buggy strncasecmp. The latter is the POSIX name, so strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper for the new strncasecmp to avoid breaking existing users. To allow the compat wrapper strnicmp to be removed at some point in the future, and to avoid the extra indirection cost, do s/strnicmp/strncasecmp/g.

2014-10-03Revert "arm: pxa: Transition pxa27x to clk framework"Mike Turquette
This reverts commit 9ff25d7b58d8a4374886843ed3ed21f1ef17bf16. Originally reported on the kernel-build-reports mailing list[0]. The problem is caused by kernel configs that select both pxa25x and pxa27x such as cm_x2xx_defconfig and palmz72_defconfig. The short term solution is to revert the patch introducing the failure. Longer term, all the PXA chips will be converted to the common clock framework allowing support for various PXA chips to build into a single image. Reverting just this one patch does introduce some dead code into the kernel, but that is offset by making it easier to convert the remaining PXA platforms to the clock framework.

2014-09-19ARM: pxa3xx: provide specific platform_devices for all ssp portsDaniel Mack
Currently, devices for SSP ports 1, 2 and 3 are registered as compatible devices to pxa27x-ssp. While the actual IP core is comparable, there are some subtle differences which users of the SSP ports address by looking at the 'type' field. By registering devices of type 'pxa27x-ssp', this 'type' field is incorrectly set to PXA27x_SSP which confuses the users. To fix this, provide specific ssp port plaform devices which use 'pxa3xx-ssp' as driver name, an instantiate them from pxa3xx.c.

2014-07-18ARM: convert all "mov.* pc, reg" to "bx reg" for ARMv6+Russell King
ARMv6 and greater introduced a new instruction ("bx") which can be used to return from function calls. Recent CPUs perform better when the "bx lr" instruction is used rather than the "mov pc, lr" instruction, and this sequence is strongly recommended to be used by the ARM architecture manual (section A.4.1.1). We provide a new macro "ret" with all its variants for the condition code which will resolve to the appropriate instruction. Rather than doing this piecemeal, and miss some instances, change all the "mov pc" instances to use the new macro, with the exception of the "movs" instruction and the kprobes code. This allows us to detect the "mov pc, lr" case and fix it up - and also gives us the possibility of deploying this for other registers depending on the CPU selection.

git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm Pull pwm changes from Thierry Reding: "The majority of these changes are cleanups and fixes across all drivers. Redundant error messages are removed and more PWM controllers set the .can_sleep flag to signal that they can't be used in atomic context. Support is added for the Broadcom Kona family of SoCs and the Intel LPSS driver can now probe PCI devices in addition to ACPI devices. Upon shutdown, the pwm-backlight driver will now power off the backlight. It also uses the new descriptor-based GPIO API for more concise GPIO handling.

Pull ARM updates from Russell King: - Major clean-up of the L2 cache support code. The existing mess was becoming rather unmaintainable through all the additions that others have done over time. This turns it into a much nicer structure, and implements a few performance improvements as well. - Clean up some of the CP15 control register tweaks for alignment support, moving some code and data into alignment.c - DMA properties for ARM, from Santosh and reviewed by DT people. This adds DT properties to specify bus translations we can't discover automatically, and to indicate whether devices are coherent. - Hibernation support for ARM - Make ftrace work with read-only text in modules - add suspend support for PJ4B CPUs - rework interrupt masking for undefined instruction handling, which allows us to enable interrupts earlier in the handling of these exceptions. - support for big endian page tables - fix stacktrace support to exclude stacktrace functions from the trace, and add save_stack_trace_regs() implementation so that kprobes can record stack traces. - Add support for the Cortex-A17 CPU. - Remove last vestiges of ARM710 support. - Removal of ARM "meminfo" structure, finally converting us solely to memblock to handle the early memory initialisation. * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (142 commits) ARM: ensure C page table setup code follows assembly code (part II) ARM: ensure C page table setup code follows assembly code ARM: consolidate last remaining open-coded alignment trap enable ARM: remove global cr_no_alignment ARM: remove CPU_CP15 conditional from alignment.c ARM: remove unused adjust_cr() function ARM: move "noalign" command line option to alignment.c ARM: provide common method to clear bits in CPU control register ARM: 8025/1: Get rid of meminfo ARM: 8060/1: mm: allow sub-architectures to override PCI I/O memory type ARM: 8066/1: correction for ARM patch 8031/2 ARM: 8049/1: ftrace/add save_stack_trace_regs() implementation ARM: 8065/1: remove last use of CONFIG_CPU_ARM710 ARM: 8062/1: Modify ldrt fixup handler to re-execute the userspace instruction ARM: 8047/1: rwsem: use asm-generic rwsem implementation ARM: l2c: trial at enabling some Cortex-A9 optimisations ARM: l2c: add warnings for stuff modifying aux_ctrl register values ARM: l2c: print a warning with L2C-310 caches if the cache size is modified ARM: l2c: remove old .set_debug method ARM: l2c: kill L2X0_AUX_CTRL_MASK before anyone else makes use of this ...

Since the trizeps4wl code is a superset of trizeps4, it makes no sense to enable just the latter, but with the current Kconfig logic, it causes the board file not to be built at all.

Due to commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051 "ARM: pxa: delete the custom GPIO header" some drivers fail compilation, for example like this: In file included from sound/soc/pxa/spitz.c:28:0: sound/soc/pxa/spitz.c: In function ‘spitz_ext_control’: arch/arm/mach-pxa/include/mach/spitz.h:111:30: error: ‘PXA_NR_BUILTIN_GPIO’ undeclared (first use in this function) #define SPITZ_SCP_GPIO_BASE (PXA_NR_BUILTIN_GPIO) (etc.) This is caused by implicit inclusion of <mach/irqs.h> from various board-specific headers under <mach/*> in the PXA platform. So we take a sweep over these, and for every such header that uses PXA_NR_BUILTIN_GPIO or PXA_GPIO_TO_IRQ() we explicitly #include "irqs.h" so that we satisfy the dependency in the board include file alone.
