Less trivial is the addition of the USB 2.0 phy driver for this SoC. The S5P210's USB 2.0 phy is nearly the same, but only nearly. The S3C6410's unit needs external power supplies to be switched on in order to make the phy work. At least the Mini6410 platform makes use of it (don't know what the other platforms do). So I added a gpio regulator to the driver. There seems already one which can be used in the devicetree, but since this phy provides two phys (one for the OTG and a second one for the OHCI) using the generic supply spits out runtime error messages because it tries to create two instances of the same name in one directory. Is there a better solution than touching the phy-samsung-usb2.c's samsung_usb2_phy_probe function? jbe Juergen Borleis (8): ARM/Mini6410: enable watchdog support ARM/DTS/S3C64XX: add syscon driver ARM/DTS/S3C64XX: add RTC device ARM/Mini6410: enable real time clock support Samsung/S3C6410/OTG-phy: add S3C6410 support ARM/DTS/S3C64XX: add an OTG phy driver for the S3C6410 SoC ARM/DTS/S3C64XX: add OHCI support ARM/Mini6410: enable USB OHCI support .../devicetree/bindings/phy/samsung-phy.txt | 2 + arch/arm/boot/dts/s3c6410-mini6410.dts | 58 ++++ arch/arm/boot/dts/s3c6410.dtsi | 8 + arch/arm/boot/dts/s3c64xx.dtsi | 40 +++ arch/arm/mach-s3c64xx/Kconfig | 1 + drivers/phy/Kconfig | 9 + drivers/phy/Makefile | 1 + drivers/phy/phy-s3c6410-usb2.c | 346 +++++++++++++++++++++ drivers/phy/phy-samsung-usb2.c | 12 + drivers/phy/phy-samsung-usb2.h | 3 + drivers/usb/host/Kconfig | 2 +- 11 files changed, 481 insertions(+), 1 deletion(-) create mode 100644 drivers/phy/phy-s3c6410-usb2.c -- 1.8.1 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
