Merge tag 'sunxi-clk-for-6.13' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into clk-allwinner
Pull Allwinner clk driver updates from Chen-Yu Tsai: - Add sigma-delta modulation settings for audio PLL on the H616 SoC, crucial for accurate audio reproduction - Constify |struct ccu_reset_map| throughout the sunxi-ng clk drivers - Fix the audio PLL divider preset on the D1 SoC - Switch to of_property_present() for checking DT property presence * tag 'sunxi-clk-for-6.13' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux: clk: sunxi-ng: Use of_property_present() for non-boolean properties clk: sunxi-ng: d1: Fix PLL_AUDIO0 preset clk: sunxi-ng: Constify struct ccu_reset_map clk: sunxi-ng: h616: Add sigma-delta modulation settings for audio PLL
