Merge branches 'clk-kunit', 'clk-mediatek', 'clk-cleanup' and 'clk-bindings' into clk-next

 - KUnit tests for clk registration and fixed rate basic clk type

* clk-kunit:
  clk: Add KUnit tests for clks registered with struct clk_parent_data
  clk: Add KUnit tests for clk fixed rate basic type
  clk: Add test managed clk provider/consumer APIs
  platform: Add test managed platform_device/driver APIs
  of: Add a KUnit test for overlays and test managed APIs
  dt-bindings: vendor-prefixes: Add "test" vendor for KUnit and friends
  of: Add test managed wrappers for of_overlay_apply()/of_node_put()
  of/platform: Allow overlays to create platform devices from the root node

* clk-mediatek:
  dt-bindings: clock: mediatek: Convert MediaTek clock syscons to schema
  dt-bindings: Move Mediatek clock controllers to "clock" directory
  dt-bindings: clock: mediatek,apmixedsys: Fix "mediatek,mt6779-apmixed" compatible
  clk: mediatek: reset: Remove unused mtk_register_reset_controller()
  clk: mediatek: reset: Return regmap's error code

* clk-cleanup:
  clk: starfive: Use pm_runtime_resume_and_get to fix pm_runtime_get_sync() usage
  clk: ti: dra7-atl: Fix leak of of_nodes
  clk:davinci: make use of dev_err_cast_probe()
  clk: bcm: bcm53573: fix OF node leak in init
  clk: lmk04832: Use devm_clk_get_enabled() helpers
  clk: visconti: Switch to use kmemdup_array()
  clk: mmp: Switch to use kmemdup_array()
  clk: hisilicon: Remove unnecessary local variable
  clk: use clk_core_unlink_consumer() helper
  clk: Use of_property_present()
  clk: at91: Use of_property_count_u32_elems() to get property length
  da8xx-cfgchip.c: replace of_node_put with __free improves cleanup

* clk-bindings:
  dt-bindings: clock: st,stm32mp1-rcc: add top-level constraints
  dt-bindings: clock: cirrus,lochnagar: add top-level constraints
  dt-bindings: clock: baikal,bt1-ccu-div: add top-level constraints
  dt-bindings: clock: nxp,lpc3220-usb-clk: Convert bindings to dtschema
  dt-bindings: clock: nxp,lpc3220-clk: Convert bindings to DT schema
