This series has 2 patches which fix some clock driver issues for RK3128.
In v2 [0] there was one more patch [1] which I dropped now, since
it has been merged already (was submitted by somebody else [2]).

From: Finley Xiao <[email protected]>
According to the TRM there are no specific gpll_peri, cpll_peri,
gpll_div2_peri or gpll_div3_peri gates, but a single clk_peri_src gate.
Instead mux_clk_peri_src directly connects to the plls respectively the pll
divider clocks.
Fix this by creating a single gated composite.
Also rename all occurrences of aclk_peri_src to clk_peri_src, since it
is the parent for peri aclks, pclks and hclks. That name also matches
the one used in the TRM.

SCLK_SDMMC is the parent for SCLK_SDMMC_DRV and SCLK_SDMMC_SAMPLE, but
used with the (more) correct name sclk_sdmmc. SD card tuning does currently
fail as the parent can't be found under that name.
There is no need to suffix the name with '0' since RK312x SoCs do have a
single sdmmc controller - so rename it to the name which is already used
by it's children.
