Merge tag 'renesas-clk-for-v6.13-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers into clk-renesas

Pull Renesas clk driver updates from Geert Uytterhoeven:

 - Add Cortex-A55 core clocks and Interrupt Control Unit (ICU) clock
   and reset on Renesas RZ/V2H(P)

* tag 'renesas-clk-for-v6.13-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers:
  clk: renesas: r8a779h0: Drop CLK_PLL2_DIV2 to clarify ZCn clocks
  clk: renesas: r9a09g057: Add clock and reset entries for ICU
  clk: renesas: r9a09g057: Add CA55 core clocks
  clk: renesas: Remove duplicate and trailing empty lines
