Merge tag 'v5.11-rockchip-clk-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-rockchip
Pull Rockchip clk driver updates from Heiko Stuebner: Added arch-dependencies for the newly added per-soc config symbols, an unneeded redundancy removed and making i2s actually work on the rk3066. * tag 'v5.11-rockchip-clk-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip: clk: rockchip: fix i2s gate bits on rk3066 and rk3188 clk: rockchip: add CLK_SET_RATE_PARENT to sclk for rk3066a i2s and uart clocks clk: rockchip: Remove redundant null check before clk_prepare_enable clk: rockchip: Add appropriate arch dependencies
