Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull more clk updates from Stephen Boyd: "Another set of clk driver updates and fixes for the merge window. The driver updates needed more time to bake in linux-next. Updates: - Support for more clk controllers in Qualcomm SoCs such as SM8350, SM8450, SDX75, SC8280XP, and IPQ9574 - Runtime PM enablement of some more Qualcomm clk controllers - Various fixes to Qualcomm clk driver data to use correct clk_ops and to check halt bits properly - AT91 updates to modernize with clk_parent_data structures Fixes: - Remove 'syscon' from dt binding fix for ti,j721e-system-controller - Fix determine rate in the Tegra driver that got wrecked by the refactorting of muxes this merge window" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (69 commits) clk: tegra: Avoid calling an uninitialized function dt-bindings: mfd: ti,j721e-system-controller: Remove syscon from example clk: at91: sama7g5: s/ep_chg_chg_id/ep_chg_id clk: at91: sama7g5: switch to parent_hw and parent_data clk: at91: sckc: switch to parent_data/parent_hw clk: at91: clk-sam9x60-pll: add support for parent_hw clk: at91: clk-utmi: add support for parent_hw clk: at91: clk-system: add support for parent_hw clk: at91: clk-programmable: add support for parent_hw clk: at91: clk-peripheral: add support for parent_hw clk: at91: clk-master: add support for parent_hw clk: at91: clk-generated: add support for parent_hw clk: at91: clk-main: add support for parent_data/parent_hw clk: qcom: gcc-sc8280xp: Add runtime PM clk: qcom: gpucc-sc8280xp: Add runtime PM clk: qcom: mmcc-msm8974: fix MDSS_GDSC power flags clk: qcom: gpucc-sm6375: Enable runtime pm dt-bindings: clock: sm6375-gpucc: Add VDD_GX clk: qcom: gcc-sm6115: Add missing PLL config properties clk: qcom: clk-alpha-pll: Add a way to update some bits of test_ctl(_hi) ...
