Hello
The following patchset adds support for the SD/MMC host found in the Allwinner SoCs.
It contains all the necessary modifications for clock environment and also the device
tree script modification which add it to all the boards using it.
The clock environment function needed for phase offset configuration has
been proposed and implemented by Emilio.
A lot of work and cleanup has been done by Hans de Goede. Special thanks to him!
This patchset is the 4th attempt to send this driver upstream.
Changes since v1:
-Using mmc_of_parse instead of diy dt parsing
-Adding nodes for all mmc controller to the dtsi files,
including sofar unused controllers
-Using generic GPIO slot library for WP/CD
-Adding additional MMC device nodes into DTSI files
Changes since v2:
-Add missing Signed-off-by tags
-Stop using __raw_readl / __raw_writel so that barriers are properly used
-Adding missing new lines
-Adding missing patch for automatic reparenting of clocks
Changes since v3:
-Move clk_enable / disable into host_init / exit (Hans)
-Fix hang on boot caused by irq storm (Hans)
regards
David
