[PATCH v5 0/3] clk: meson: add a sub EMMC clock controller support

This driver will add a MMC clock controller driver support.
The original idea about adding a clock controller is during the
discussion in the NAND driver mainline effort[1].

This driver is tested in the S400 board (AXG platform) with NAND driver.

Changes since v4 [5]:
- use struct parm in phase delay driver
- remove 0 delay releted part in phase delay driver
- don't rebuild the parent name once again
- add divider ops with .init

Changes since v3 [4]:
- separate clk-phase-delay driver
- replace clk_get_rate() with clk_hw_get_rate()
- collect Rob's R-Y
- drop 'meson-' prefix from compatible string

Changes since v2 [3]:
- squash dt-binding clock-id patch
- update license
- fix alignment
- construct a clk register helper() function

Changes since v1 [2]:
- implement phase clock
- update compatible name
- adjust file name
- divider probe() into small functions, and re-use them
