Uwe Kleine-König	4a1caed3d0	clk: make several parent names const ... Since commit 2893c379461a ("clk: make strings in parent name arrays const") the name of parent clocks can be const. So add more const in several clock drivers.

Alexandru M Stan	89bf26cbc1	clk: rockchip: Add support for the mmc clock phases using the framework ... This patch adds the 2 physical clocks for the mmc (drive and sample). They're mostly there for the phase properties, but they also show the true clock (by dividing by RK3288_MMC_CLKGEN_DIV). The drive and sample phases are generated by dividing an upstream parent clock by 2, this allows us to adjust the phase by 90 deg. There's also an option to have up to 255 delay elements (40-80 picoseconds long). This driver uses those elements (under the assumption that they're 60 ps long) to generate approximate 22.5 degrees options. 67.5 (22.5*3) might be as high as 90 deg if the delay elements are as big as 80 ps, so a finer division (smaller than 22.5) was not picked because the phase might not be monotonic anymore.
