2015-10-08ARM: dts: Use GPIO constants for flags cells in exynos5420/5422/5800 boardsJavier Martinez Canillas1-3/+4
The board DTS are using numeric values instead of the defined GPIO constanst to express polarity, use them to make the DTS more clear. Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Kukjin Kim <kgene@kernel.org>

2015-03-27ARM: dts: Add HS400 support for exynos5420 and exynos5800Seungwon Jeon1-1/+4
HS400 timing values are added for SMDK5420, exynos5420-peach-pit and exynos5800-peach-pi boards. This also adds RCLK GPIO line, this gpio should be in pull-down state. This also enables HS400 on peach-pi and this updates the clock frequency to 800MHz to be set as input clock to controller.

2015-02-27ARM: dts: Mux XMMCnDATA[0] pad correctly for Exynos5420 boardsJavier Martinez Canillas1-2/+2
The Exynos5420 SoC has 3 sets of 8 pads used as data lines for the 3 MMC/SD/SDIO slots. These needs to be muxed as SD_n_DATA instead of a GPIO or external interrupt to allow the MMC controller to communicate with the attached cards or SDIO devices. Which data lines needs to be muxed as SD_n_DATA depends on the bus width used for data transfer: * bus-width = <1> needs SD_n_DATA[0] * bus-width = <4> needs SD_n_DATA[0-3] * bus-width = <8> needs SD_n_DATA[0-7] The Exynos5250-pinctrl.dtsi file that defines the groups of pins has SD_n_DATA[0] muxed for both sdn_bus1 and sdn_bus4 so just one of them needs to be included in the device node's pinctrl property. But Exynos5420-pinctrl has a different definition and only includes SD_n_DATA[1-3] for sdn_bus4. So for a bus-width = <4>, both sdn_bus1 and sdn_bus4 have to be in the dev pinctrl to mux all the needed pads. It seems all Exynos5420 boards had just cargo cult the pinctrl lines assuming that sdn_bus4 also included SD_n_DATA[0] and it only works because the bootloader muxes the pads correctly. But that is not the case for the devices not used by the bootloader such as WiFi modules. Add sdn_bus1 too in the nodes pinctrl to not rely on the bootloader.

2014-08-18ARM: dts: unuse the slot-node and deprecate the supports-highspeed for dw-mmc in exynosJaehoon Chung1-12/+4
dw-mmc controller can support multiple slots. But, there are no use-cases anywhere. So we don't need to support the slot-node for dw-mmc controller. And "supports-highspeed" property in dw-mmc is deprecated. "supports-highspeed" property can be replaced with "cap-sd/mmc-highspeed".
