Merge tag 'clk-meson-v5.11-1' of https://github.com/BayLibre/clk-meson into clk-amlogic
Pull Amlogic clk driver updates from Jerome Brunet: - Add MIPI DSI clocks for axg and g12 - Make it possible to build controllers as modules - Fix Video PLL clock dependency * tag 'clk-meson-v5.11-1' of https://github.com/BayLibre/clk-meson: clk: meson: g12a: add MIPI DSI Host Pixel Clock dt-bindings: clk: g12a-clkc: add DSI Pixel clock bindings clk: meson: enable building as modules clk: meson: Kconfig: fix dependency for G12A clk: meson: axg: add MIPI DSI Host clock clk: meson: axg: add Video Clocks dt-bindings: clk: axg-clkc: add MIPI DSI Host clock binding dt-bindings: clk: axg-clkc: add Video Clocks clk: meson: g12: use devm variant to register notifiers clk: add devm variant of clk_notifier_register clk: meson: g12: drop use of __clk_lookup() clk: add api to get clk consumer from clk_hw clk: avoid devm_clk_release name clash
