This commit taken from Rabeeh's Cubox kernel and re-worked for DT;
Sebastian Hasselbrath is believed to be the original author.
Some Cuboxes require a GPIO for card detection; this implements the
optional GPIO support for card detection. This GPIO is logic 0 for
card inserted.

Use devm_clk_get() rather than clk_get() to make cleanup paths more simple.

The following three patches allow sdhci-dove to use a GPIO for card
presence detection. This is a three stage process:
1. Clean up error paths by using devm_clk_get().
2. Use the two-stage sdhci initialization.
3. Implement the GPIO card detection support.
A very similar patch has been tested by

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.

The exynos code claimed wp-gpio 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.
A future change will move the wp-gpio support to the core dw_mmc.c
file. Now the exynos-specific code won'

Thanks for the review. See below for comments. I'll plan on a new

Hi
Here is SDHCI ACPI driver. It is dependent on new ACPI Platform support
so I suggest Rafael takes the patches with Chris' Ack.
Please note that I would prefer this to be queued for 3.8

Hi,

It can be reused for EXYNOS platform? We need to modify some though.

support 1.8V voltage, but the peripheral hardware circuit has
capability to support 3.3V voltage.
