Pull ARM SoC driver updates from Olof Johansson: "Driver updates for v4.1. Some of these are for drivers/soc, where we find more and more SoC-specific drivers these days. Some are for other driver subsystems where we have received acks from the appropriate maintainers. The larger parts of this branch are: - MediaTek support for their PMIC wrapper interface, a high-level interface for talking to the system PMIC over a dedicated I2C interface. - Qualcomm SCM driver has been moved to drivers/firmware. It's used for CPU up/down and needs to be in a shared location for arm/arm64 common code. - cleanup of ARM-CCI PMU code. - another set of cleanusp to the OMAP GPMC code" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (43 commits) soc/mediatek: Remove unused variables clocksource: atmel-st: select MFD_SYSCON soc: mediatek: Add PMIC wrapper for MT8135 and MT8173 SoCs arm-cci: Fix CCI PMU event validation arm-cci: Split the code for PMU vs driver support arm-cci: Get rid of secure transactions for PMU driver arm-cci: Abstract the CCI400 PMU specific definitions arm-cci: Rearrange code for splitting PMU vs driver code drivers: cci: reject groups spanning multiple HW PMUs ARM: at91: remove useless include clocksource: atmel-st: remove mach/hardware dependency clocksource: atmel-st: use syscon/regmap ARM: at91: time: move the system timer driver to drivers/clocksource ARM: at91: properly initialize timer ARM: at91: at91rm9200: remove deprecated arm_pm_restart watchdog: at91rm9200: implement restart handler watchdog: at91rm9200: use the system timer syscon mfd: syscon: Add atmel system timer registers definition ARM: at91/dt: declare atmel,at91rm9200-st as a syscon soc: qcom: gsbi: Add support for ADM CRCI muxing ...

memory: jz4780-nemc: driver for the NEMC on JZ4780 SoCs

2015-03-26T22:51:36Z

Add a driver for the NAND/External Memory Controller (NEMC) on JZ4780 and later SoCs. The primary function of this driver is to configure parameters, such as timings, for external memory devices using data supplied in the device tree. Devices connected to the NEMC are represented in the DT as children of the NEMC node, the driver uses optional properties specified in these child nodes to configure the parameters of each bank.

ARM OMAP2+ GPMC: fix programming/showing reserved timing parameters

2015-03-06T10:55:32Z

GPMC_CONFIG1_i parameters CLKACTIVATIONTIME and WAITMONITORINGTIME have reserved values. Raise an error if calculated timings try to program reserved values. GPMC_CONFIG1_i ATTACHEDDEVICEPAGELENGTH and DEVICESIZE were already checked when parsing the DT. Explicitly comment invalid values on gpmc_cs_show_timings for -CLKACTIVATIONTIME -WAITMONITORINGTIME -DEVICESIZE -ATTACHEDDEVICEPAGELENGTH Signed-off-by: Robert ABEL Acked-by: Tony Lindgren Signed-off-by: Roger Quadros

ARM OMAP2+ GPMC: fix WAITMONITORINGTIME divider bug

2015-03-06T10:46:06Z

The WAITMONITORINGTIME is expressed as a number of GPMC_CLK clock cycles, even though the access is defined as asynchronous, and no GPMC_CLK clock is provided to the external device. Still, GPMCFCLKDIVIDER is used as a divider for the GPMC clock, so it must be programmed to define the correct WAITMONITORINGTIME delay. This patch correctly computes WAITMONITORINGTIME in GPMC_CLK cycles instead of GPMC_FCLK cycles, both during programming (gpmc_cs_set_timings) and during retrieval (gpmc_cs_show_timings).

ARM OMAP2+ GPMC: calculate GPMCFCLKDIVIDER based on WAITMONITORINGTIME

2015-03-06T10:39:48Z

The WAITMONITORINGTIME is expressed as a number of GPMC_CLK clock cycles, even though the access is defined as asynchronous, and no GPMC_CLK clock is provided to the external device. Still, GPMCFCLKDIVIDER is used as a divider for the GPMC clock, so it must be programmed to define the correct WAITMONITORINGTIME delay. Calculate GPMCFCLKDIVIDER independent of gpmc,sync-clk-ps in DT for pure asynchronous accesses, i.e. both read and write asynchronous.

ARM OMAP2+ GPMC: change get_gpmc_timing_reg output for DTS

2015-03-06T10:34:28Z

DTS output was formatted to require additional work when copy-pasting into DTS. Nano-second timings were replaced with interval of values that produce the same number of clock ticks. Signed-off-by: Robert ABEL Acked-by: Tony Lindgren Signed-off-by: Roger Quadros

ARM OMAP2+ GPMC: fix debug output alignment

2015-03-06T10:23:21Z

GPMC debug output is aligned to 10 characters for field names. However, some fields have bigger names, screwing up the alignment. Consequently, alignment was changed to longest field name (17 chars) for now. Signed-off-by: Robert ABEL Acked-by: Tony Lindgren Signed-off-by: Roger Quadros

ARM OMAP2+ GPMC: don't undef DEBUG

2015-03-06T10:15:20Z

OMAP2+ GPMC driver undefines DEBUG, which makes it unnecessarily hard to turn DEBUG on. Remove the offending lines. Signed-off-by: Robert ABEL Acked-by: Tony Lindgren Signed-off-by: Roger Quadros
