Merge tag 'renesas-clk-for-v6.16-tag2' 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/G3E * tag 'renesas-clk-for-v6.16-tag2' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers: clk: renesas: r9a09g047: Add XSPI clock/reset clk: renesas: r9a09g047: Add support for xspi mux and divider dt-bindings: clock: renesas,r9a09g047-cpg: Add XSPI and GBETH PTP core clocks clk: renesas: Use str_on_off() helper
