[PATCH v2 0/2] clk/mediatek: Adjustments for MSDC rate accuracy

[AngeloGioacchino Del Regno]

Changes in v2:
  - Extended the changes in this series to MT8365 clocks

This series stops unconditionally forcing CLK_SET_RATE_PARENT on
MediaTek muxes, as that should be set in the clock driver for each
clock requiring it, and removes CLK_SET_PARENT from all MSDC core
clocks to allow mtk-sd to select the right clock parent when doing
mclk setting, improving the rate accuracy and avoiding both under
and overclocks of the eMMC/SD/SDIO card, both improving performance
and stability of the attached storage.

This series was successfully tested on MT8173, MT8192, MT8195.

[PATCH v2 1/2] clk: mediatek: mux: Stop forcing CLK_SET_RATE_PARENT flag

[AngeloGioacchino Del Regno]

The clk-mux driver was forcing the CLK_SET_RATE_PARENT flag even for
the GATE_CLK_SET_UPD_FLAGS() macro, as in mtk_clk_register_mux() the
flag was unconditionally added.

In preparation for a change on MSDC clock muxes, stop forcing this
flag and, where necessary, update clock drivers to add it so that
with this commit we introduce no functional changes for the currently
supported SoCs.

[PATCH v2 2/2] clk: mediatek: Remove CLK_SET_PARENT from all MSDC core clocks

[AngeloGioacchino Del Regno]

Various MSDC core clocks, used for multiple MSDC controller instances,
share the same parent(s): in order to add parents selection in the
mtk-sd driver to achieve an accurate clock rate for all modes, remove
the CLK_SET_RATE_PARENT flag from all MSDC clocks for all SoCs: this
will make sure that a clk_set_rate() call performed for a clock on
a secondary controller will not change the rate of a common parent,
which would result in an overclock or underclock of one of the
controllers.
