Merge tag 'clk-renesas-for-v4.12-tag2' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers into clk-next

Pull Renesas clk driver updates from Geert Uytterhoeven:

  - Add support for the Clock Pulse Generator / Module Standby and
    Software Reset module on revision ES2.0 of the R-Car H3 SoC, which
    differs from ES1.x in some areas.
  - Add IMR clocks for R-Car H3 and M3-W,
  - Add workaround for PLL0/2/4 errata on R-Car H3 ES1.0,
  - Small fixes and cleanups.
