Pull ARM SoC cleanups on various subarchitectures from Olof Johansson: "Cleanup patches for various ARM platforms and some of their associated drivers. There's also a branch in here that enables Freescale i.MX to be part of the multiplatform support -- the first "big" SoC that is moved over (more multiplatform work comes in a separate branch later during the merge window)." Conflicts fixed as per Olof, including a silent semantic one in arch/arm/mach-omap2/board-generic.c (omap_prcm_restart() was renamed to omap3xxx_restart(), and a new user of the old name was added). * tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (189 commits) ARM: omap: fix typo on timer cleanup ARM: EXYNOS: Remove unused regs-mem.h file ARM: EXYNOS: Remove unused non-dt support for dwmci controller ARM: Kirkwood: Use hw_pci.ops instead of hw_pci.scan ARM: OMAP3: cm-t3517: use GPTIMER for system clock ARM: OMAP2+: timer: remove CONFIG_OMAP_32K_TIMER ARM: SAMSUNG: use devm_ functions for ADC driver ARM: EXYNOS: no duplicate mask/unmask in eint0_15 ARM: S3C24XX: SPI clock channel setup is fixed for S3C2443 ARM: EXYNOS: Remove i2c0 resource information and setting of device names ARM: Kirkwood: checkpatch cleanups ARM: Kirkwood: Fix sparse warnings.

* Freescale Inter IC (I2C) and High Speed Inter IC (HS-I2C) for i.MX
|
|
|
|
Required properties:
|
|
- compatible : Should be "fsl,<chip>-i2c"
|
|
- reg : Should contain I2C/HS-I2C registers location and length
|
|
- interrupts : Should contain I2C/HS-I2C interrupt
|
|
|
|
Optional properties:
|
|
- clock-frequency : Constains desired I2C/HS-I2C bus clock frequency in Hz.
|
|
The absence of the propoerty indicates the default frequency 100 kHz.
|
|
|
|
Examples:
|
|
|
|
i2c@83fc4000 { /* I2C2 on i.MX51 */
|
|
compatible = "fsl,imx51-i2c", "fsl,imx21-i2c";
|
|
reg = <0x83fc4000 0x4000>;
|
|
interrupts = <63>;
|
|
};
|
|
|
|
i2c@70038000 { /* HS-I2C on i.MX51 */
|
|
compatible = "fsl,imx51-i2c", "fsl,imx21-i2c";
|
|
reg = <0x70038000 0x4000>;
|
|
interrupts = <64>;
|
|
clock-frequency = <400000>;
|
|
};
