2014-11-26mmc: dw_mmc: Add support for IMG PistachioAndrew Bresticker1-0/+29
Add support for the DW MMC host found on the Imagination Pistachio SoC. Like the DW MMC hosts found on SOCFPGA and Rockchip SoCs, the DW MMC host on Pistachio requires the use of SDMMC_CMD_USE_HOLD_REG.

2014-09-09mmc: implement Driver Stage Register handlingSascha Hauer1-0/+2
Some eMMC and SD cards implement a DSR register that allows to tune raise/fall times and drive strength of the CMD and DATA outputs. The values to use depend on the card in use and the host. It might be needed to reduce the drive strength to prevent voltage peaks above the host's specification. Implement a 'dsr' devicetree property that allows to specify the value to set the DSR to. For non-dt setups the new members of mmc_host can be set by board code. This patch was initially authored by Sascha Hauer. It contains improvements authored by Markus Niebel and Uwe Kleine-König.

The am335x can't detect pending cirq in PM runtime suspend. This patch reconfigures dat1 as a GPIO before going to suspend. SDIO interrupts are detected with the GPIO, the GPIO will only wake the module from suspend, SDIO irq detection will still happen through the IP block. Idea of remuxing the pins by Tony Lindgren.

2014-07-09mmc: omap_hsmmc: Enable SDIO interruptAndreas Fenkart1-0/+1
There have been various patches floating around for enabling the SDIO IRQ for hsmmc, but none of them ever got merged. Probably the reason for not merging the SDIO interrupt patches has been the lack of wake-up path for SDIO on some omaps that has also needed remuxing the SDIO DAT1 line to a GPIO making the patches complex. This patch adds the minimal SDIO IRQ support to hsmmc for omaps that do have the wake-up path. For those omaps, the DAT1 line need to have the wake-up enable bit set, and the wake-up interrupt is the same as for the MMC controller. This patch has been tested on am3730 es1.2 with mwifiex connected to MMC3 with mwifiex waking to Ethernet traffic from off-idle mode. Note that for omaps that do not have the SDIO wake-up path, this patch will not work for idle modes and further patches for remuxing DAT1 to GPIO are needed. Based on earlier patches [1][2] by David Vrabel <david.vrabel@csr.com>, Steve Sakoman <steve@sakoman.com> For now, only support SDIO interrupt if we are booted with a separate wake-irq configued via device tree. This is because omaps need the wake-irq for idle states, and some omaps need special quirks. And we don't want to add new legacy mux platform init code callbacks any longer as we are moving to DT based booting anyways. To use it, you need to specify the wake-irq using the interrupts-extended property.

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.

2013-12-11ARM: tegra: document reset properties in DT bindingsStephen Warren1-0/+6
Update all the Tegra DT bindings to require resets/reset-names properties where the HW module has reset inputs. Remove any entries from clocks or clock-names that were only required to identify reset inputs, rather than referring to real clocks. This is a DT-ABI-incompatible change. It is the first of two changes required for me to consider the Tegra DT bindings as stable, the other being conversion to the common DMA DT bindings.
