Merge tag 'renesas-clk-for-v6.20-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 Expanded Serial Peripheral Interface (xSPI) clocks and resets on
   Renesas RZ/T21H and RZ/N2H
 - Add DMAC, interrupt controller (ICU), SPI, and thermal (TSU) clocks
   and resets on Renesas RZ/V2N
 - Add more serial (RSCI) clocks and resets on Renesas RZ/V2H and RZ/V2N
