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.

AM33XX MUSB GLUE
|
|
- compatible : Should be "ti,musb-am33xx"
|
|
- reg : offset and length of register sets, first usbss, then for musb instances
|
|
- interrupts : usbss, musb instance interrupts in order
|
|
- ti,hwmods : must be "usb_otg_hs"
|
|
- multipoint : Should be "1" indicating the musb controller supports
|
|
multipoint. This is a MUSB configuration-specific setting.
|
|
- num-eps : Specifies the number of endpoints. This is also a
|
|
MUSB configuration-specific setting. Should be set to "16"
|
|
- ram-bits : Specifies the ram address size. Should be set to "12"
|
|
- port0-mode : Should be "3" to represent OTG. "1" signifies HOST and "2"
|
|
represents PERIPHERAL.
|
|
- port1-mode : Should be "1" to represent HOST. "3" signifies OTG and "2"
|
|
represents PERIPHERAL.
|
|
- power : Should be "250". This signifies the controller can supply upto
|
|
500mA when operating in host mode.
|
|
|
|
Example:
|
|
|
|
usb@47400000 {
|
|
compatible = "ti,musb-am33xx";
|
|
reg = <0x47400000 0x1000 /* usbss */
|
|
0x47401000 0x800 /* musb instance 0 */
|
|
0x47401800 0x800>; /* musb instance 1 */
|
|
interrupts = <17 /* usbss */
|
|
18 /* musb instance 0 */
|
|
19>; /* musb instance 1 */
|
