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 90
--
sclk_sdmmc 1 1 297000000 0 0
sdmmc_sample 0 0 148500000 0 134
sdmmc_drv 0 0 148500000 0 90
--
sclk_sdio0 1 1 100000000 0 0
sdio0_sample 0 0 50000000 0 0
sdio0_drv 0 0 50000000 0 90
sclk_emmc 1 1 100000000 0 0
emmc_sample 0 0 50000000 0 0
emmc_drv 0 0 50000000 0 180
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 v3:
- renamed everything internal from phase to just mmc_clock or mmc
- added RK3288_MMC_CLKGEN_DIV instead of the magic number
- added new paragraph to commit message
Changes in v2:
- fixed my cc/to list
- removed dangling #DEFINE DEBUG
