Re: [PATCH v4 00/12] iommu/exynos: Fixes and Enhancements of System MMU driver with DT

Hi Mr. Cho, We have verified the above patchset for following usecases on exynos5. 1) MFC decoding using Sysmmu_L and R. (with the bit Inversion fix) 2) GSC operations. 3) FIMD and MIXER (HDMI) as displays. Thanks for your effort. regards, Rahul Sharma. On Thu, Nov 29, 2012 at 4:25 PM, Cho

[PATCH v3 3/4] mmc: dw_mmc: exynos: Remove code for wp-gpios

The exynos code claimed the write protect with devm_gpio_request() but never did anything with it. That meant that anyone using a write protect GPIO would effectively be write protected all the time. The handling for wp-gpios belongs in the main dw_mmc driver and has been moved there.

[PATCH v3 4/4] mmc: dw_mmc: Handle wp-gpios from device tree

On some SoCs (like exynos5250) you need to use an external GPIO for write protect. Add support for wp-gpios to the core dw_mmc driver since it could be useful across multiple SoCs. With this change I am able to make use of the write protect for the external SD slot on exynos5250-snow.

[PATCH v3 1/4] mmc: dw_mmc: Add disable-wp device tree property

The disable-wp property is used to specify that a given SD card slot doesn't have a concept of write protect. This eliminates the need for special case code for SD slots that should never be write protected (like a micro SD slot or a dev board). The dw_mmc driver is special in needing to specify
