Based on the proof-of-concept R8A7791 CPG/MSSR patch by Geert Uytterhoeven . Signed-off-by: Sergei Shtylyov Acked-by: Rob Herring Reviewed-by: Geert Uytterhoeven --- Changes in version 5: - describe the Z clock as PLL0/VCO divided by 2. Changes in version 4: - made use of the new RST driver's API to read the mode pins; - cleaned up the table copied from the manual, fixed the manual reference. Changes in version 3: - exchanged Audio-DMAC0/1 entries in r8a7743_mod_clks[]; - renamed the I2C6 entry to IICDVFS; - fixed the comment to the INTC-SYS entry in r8a7743_crit_mod_clks[]; - removed the useless EXTAL divisor check from r8a7743_cpg_mssr_init(); - added Rob's ACK and Geert's tag. Changes in version 2: - documented the R8A7743 device tree binding; - fixed whitespace errors/warnings reported by checkpatch.pl; - used tabs instead of spaces for indentation; - fixed the PLL3 column name in the PLL table.
