[PATCH v6 0/4] mmc: sdhci-of-arasan: Enable UHS-1 support for Keem Bay SOC

[muhammad.husaini.zulkifli at intel.com]

From: Muhammad Husaini Zulkifli <muhammad.husaini.zulkifli at intel.com>

Hello

This patch series adds UHS-1 Support for Keem Bay SOC.

Patch 1 : Add struct device *dev in probe func(),so that dev pointer can be widely use in probe to make code more readable.
Patch 2 : Export function to be use by device driver to configure voltage rail output.
Patch 3 : Defined the DT binding to support the UHS-1 operation.
Patch 4 : Gives an overview of how voltage operations happen to support UHS-1 mode for Keem Bay SOC.

All of these patches was tested with Keem Bay evaluation module board.

Kindly help to review this patch set.

Thank you.

Changes since v5:
- Restructured voltage operation for io bus line in one function and added comments in sdhci-of-arasan.c.
- Use gpio regulator modelling for expander pins.
- Add DT Bindings for phys, vmmc and vqmmc supplies.
- Renamed func name and added comments for firmware header files.
- Update commit message for each patchs to describe what goes on.

Changes since v4:
- Fixed comment by Andy and Sudeep on first patch.
- Add Acked-by tag.
- Fixed comment by Michal and Andy on the third patch to replace current users of &pdev->dev.

Changes since v3:
- Add Dt bindings for uhs gpio.
- Fixed comment by Michal and Sudeep on header file for the macro and error code.
- Fixed comment by Andy and created 1 new patch to separate the struc dev pointer in probe func.
- Fixed comment by Michal in arasan controller code.

Changes since v2:
- Removed Document DT Bindings for Keembay Firmware.
- Removed Firmware Driver to handle ATF Service call.
- Add header file to handle API function for device driver to communicate with Arm Trusted Firmware.

Changes since v1:
- Add Document DT Bindings for Keembay Firmware.
- Created Firmware Driver to handle ATF Service call.
- Provide API for arasan driver for sd card voltage changes.
