2018-01-29cfi_flash: Add missing braces in blocksMario Six
In if/else statements, either both blocks (if and else) should have braces or both blocks should not have braces, but mixed configurations are discouraged. Fix all instances where this occurs. Signed-off-by: Mario Six <mario.six@gdsys.cc> Signed-off-by: Stefan Roese <sr@denx.de>
2018-01-29cfi_flash: Remove unnecessary bracesMario Six
"==" and "!=" bind tighter than the boolean operators, so parentheses around them in compound logical statements are unnecessary. Fix all instances where this occurs. Signed-off-by: Mario Six <mario.six@gdsys.cc> Signed-off-by: Stefan Roese <sr@denx.de>

2018-01-28bcm2835_pinctrl: Probe pre-relocAlexander Graf
The serial drivers now depend on the pinctrl driver to determine whether they are enabled. That means if a serial device wants to be used pre-reloc, we also need the pinctrl device pre-reloc. Adapt the pinctrl driver as well as dts overlay accordingly. Signed-off-by: Alexander Graf <agraf@suse.de>
2018-01-28bcm2835_pl011_serial: Add BCM2835 specific serial driverAlexander Graf
On bcm2835 we need to ensure we only access serial devices that are muxed to the serial output pins of the pin header. To achieve this for the pl011 device, add a bcm2835 specific pl011 wrapper device that does this check but otherwise behaves like a pl011 device. Signed-off-by: Alexander Graf <agraf@suse.de>

2018-01-28serial_bcm283x_mu: Fail loading if not muxedAlexander Graf
The bcm283x mini-uart is only really usable as U-Boot serial output when it is muxed to the UART pins of the RPi pin header. So fail probing in case it is not muxed correctly, as in that case firmware did not initialize it properly either. Signed-off-by: Alexander Graf <agraf@suse.de>
2018-01-28serial_bcm283x_mu: Always skip initAlexander Graf
The serial initialization doesn't always quite work for me, so let's always skip it for now. We know that firmware on the RPi initializes us properly already. Signed-off-by: Alexander Graf <agraf@suse.de>
2018-01-28serial_bcm283x_mu: Convert to dev_readAlexander Graf
The fdtdec API got deprecated in favor of dev_read calls. Use those instead. Signed-off-by: Alexander Graf <agraf@suse.de>
2018-01-28serial: bcm283x_mu: Remove support for post-init disablingAlexander Graf
We are switching to a model where a serial device doesn't even get probed when it's not muxed properly, so we don't need device specific disabling functionality anymore. Signed-off-by: Alexander Graf <agraf@suse.de>
2018-01-28serial: Use next serial device if probing failsAlexander Graf
Currently our serial device search chokes on the fact that the serial probe function could fail. If it does, instead of searching for the next usable serial device, it just quits. This patch changes the fallback logic so that even when a serial device was not probed correctly, we just try the next ones until we find one that works.

2018-01-28mmc: Add bcm2835 sdhost controllerAlexander Graf
The BCM2835 family of SoCs has 2 different SD controllers: One based on the SDHCI spec and a custom, home-grown one. This patch implements a driver for the latter based on the Linux driver. This is needed so that we can make use of device trees that assume driver presence of both SD controllers. Signed-off-by: Alexander Graf <agraf@suse.de>
2018-01-28bcm283x: Add pinctrl driverAlexander Graf
The bcm283x family of SoCs have a GPIO controller that also acts as pinctrl controller. This patch introduces a new pinctrl driver that can actually properly mux devices into their device tree defined pin states and is now the primary owner of the gpio device. The previous GPIO driver gets moved into a subdevice of the pinctrl driver, bound to the same OF node. That way whenever a device asks for pinctrl support, it gets it automatically from the pinctrl driver and GPIO support is still available in the normal command line phase.

2018-01-28clk: implement clk_set_defaults()Philipp Tomsich
Linux uses the properties 'assigned-clocks', 'assigned-clock-parents' and 'assigned-clock-rates' to configure the clock subsystem for use with various peripheral nodes. This implements clk_set_defaults() and hooks it up with the general device probibin in drivers/core/device.c: when a new device is probed, clk_set_defaults() will be called for it and will process the properties mentioned above. Note that this functionality is designed to fail gracefully (i.e. if a clock-driver does not implement set_parent(), we simply accept this and ignore the error) as not to break existing board-support.

2018-01-28rockchip: clk: rk3399: implement set_parent() operationPhilipp Tomsich
This implements the (newly added) set_parent() operation for the RK3399 with a focus on allowing the RGMII clock parent to be configured via the assigned-clock-parents property of the GMAC node. This implementation supports only the GMAC (in fact only the RGMII clock parent) and allows to set this clock's parent either to the internal SCLK_GMAC or to an external clock input (identifiable by it providing a 'clock-output-name' of "gmac_clkin").

2018-01-28clk: refactor clk_get_by_index() into clk_get_by_indexed_prop()Philipp Tomsich
The logic in clk_get_by_index() may be useful for other properties than 'clocks': e.g. 'assigned-clocks' and 'assigned-clock-parents' follows the same model. This commit refactors clk_get_by_index() by introducing an internal function clk_get_by_indexed_prop() that allows to specify the name of the property to process. The original clk_get_by_index() call is simply directed through this helper function with the property name fixed to "clocks".
