I have not seen "clk-table" and "clk-table-num" before. Are these standard
properties? What are the units that are used here, what does the index mean?
"clk-table" and "clk-table-num" are private properties.
Instead simply on/off, the ip need different ciu clock for each timing mode.
Take emmc as example,
clk-table-num = <8>;
clk-table =
<13000000 50000000 0 0 13000000 50000000 0 100000000>;
MMC_TIMING_LEGACY mode, 25M should be set with parent clock 180M,
MMC_TIMING_MMC_HS mode, 50M is required with parent clock 360M
"clk-table" list all clocks to be set in all supported timing one by one.
"clk-table-num" is the table number, since not find function getting
table number.
For example, next version will support MMC_TIMING_MMC_HS200 mode, the
clk-table-num = <9> with 9 clocks in the "clk-table"
Thanks
