2015-01-29mmc: sdhci-pxav3: Extend binding with SDIO3 conf reg for the Armada 38xGregory CLEMENT1-4/+11
The SDHCI unit used on the Armada 38x needs using an extra register to do specific clock adjustments in order to support the SDR50 and DDR50 modes. This patch extends the binding to allow using this register. Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2014-11-10mmc: sdhci-pxav3: Document clocks and additional clock-names propertySebastian Hesselbarth1-0/+7
Now that sdhci-pxav3 driver allows to have more than one IP clock defined, document both clocks and clock-names properties. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2014-03-29mmc: sdhci-pxav3: add support for the Armada 38x SDHCI controllerMarcin Wojtas1-1/+16
The SDHCI unit used on the Armada 380 and 385 Marvell SoC is similar to the PXAv3 unit. The only difference is that on Armada 38x, the PXAv3 unit accesses memory through MBus windows which must be configured prior to using the device. Without this, DMA would not work. In order to achieve this, the sdhci-pxav3 driver is extended with an additional compatible string "marvell,armada-380-sdhci". When this compatible string is used, the MBus windows are initialized in a way that is identical to what all other DMA-capable drivers for Marvell EBU platforms do.
