For now all I have is the getter and setter for the phase, nothing that uses it
(that is ready). You can test the getter like this:
localhost ~ # cat /sys/kernel/debug/clk/clk_summary|grep sample -C 1
sclk_sdio1 0 0 24000000 0 0
sdio1_sample 0 0 12000000 0 0
sdio1_drv 0 0 12000000 0

sclk_sdmmc 1 1 297000000 0 0
sdmmc_sample 0 0 148500000 0

sdmmc_drv 0 0 148500000 0

sclk_sdio0 1 1 100000000 0 0
sdio0_sample 0 0 50000000 0 0
sdio0_drv 0 0 50000000 0

sclk_emmc 1 1 100000000 0 0
emmc_sample 0 0 50000000 0 0
emmc_drv 0 0 50000000 0

Next thing that will come is some dts changes that will make use of these new
clocks, and eventually mmc code will be changed to tune with these clocks.
Changes in v2:
- fixed my cc/to list
- removed dangling #DEFINE DEBUG

clk: rockchip: add bindings for the mmc clock phases
