Merge tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk fixes from Stephen Boyd: "A set of clk fixes for the Qualcomm, Mediatek, and Allwinner drivers: - Fix the Qualcomm Stromer Plus PLL set_rate() clk_op to explicitly set the alpha enable bit and not set bits that don't exist - Mark Qualcomm IPQ9574 crypto clks as voted to avoid stuck clk warnings - Fix the parent of some PLLs on Qualcomm sm6530 so their rate is correct - Fix the min/max rate clamping logic in the Allwinner driver that got broken in v6.9 - Limit runtime PM enabling in the Mediatek driver to only mt8183-mfgcfg so that system wide resume doesn't break on other Mediatek SoCs" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: clk: mediatek: mt8183: Only enable runtime PM on mt8183-mfgcfg clk: sunxi-ng: common: Don't call hw_to_ccu_common on hw without common clk: qcom: gcc-ipq9574: Add BRANCH_HALT_VOTED flag clk: qcom: apss-ipq-pll: remove 'config_ctl_hi_val' from Stromer pll configs clk: qcom: clk-alpha-pll: set ALPHA_EN bit for Stromer Plus PLLs clk: qcom: gcc-sm6350: Fix gpll6* & gpll7 parents
