clk: mediatek: pll: Split definitions into separate header file When the PLL type clk was implemented in the MediaTek clk driver library, the data structure definitions and function declaration were put in the common header file. Since it is its own type of clk, and not all platform clk drivers utilize it, having the definitions in the common header results in wasted cycles during compilation. Split out the related definitions and declarations into its own header file, and include that only in the platform clk drivers that need it.

clk: mediatek: clk-gate: Propagate struct device with mtk_clk_register_gates() Commit e4c23e19aa2a ("clk: mediatek: Register clock gate with device") introduces a helper function for the sole purpose of propagating a struct device pointer to the clk API when registering the mtk-gate clocks to take advantage of Runtime PM when/where needed and where a power domain is defined in devicetree. Function mtk_clk_register_gates() then becomes a wrapper around the new mtk_clk_register_gates_with_dev() function that will simply pass NULL as struct device: this is essential when registering drivers with CLK_OF_DECLARE instead of as a platform device, as there will be no struct device to pass... but we can as well simply have only one function that always takes such pointer as a param and pass NULL when unavoidable. This commit removes the mtk_clk_register_gates() wrapper and renames mtk_clk_register_gates_with_dev() to the former and all of the calls to either of the two functions were fixed in all drivers in order to reflect this change; also, to improve consistency with other kernel functions, the pointer to struct device was moved as the first param. Since a lot of MediaTek clock drivers are actually registering as a platform device, but were still registering the mtk-gate clocks without passing any struct device to the clock framework, they've been changed to pass a valid one now, as to make all those platforms able to use runtime power management where available. While at it, some much needed indentation changes were also done.

clk: mediatek: clk-gate: Propagate struct device with mtk_clk_register_gates() Commit e4c23e19aa2a ("clk: mediatek: Register clock gate with device") introduces a helper function for the sole purpose of propagating a struct device pointer to the clk API when registering the mtk-gate clocks to take advantage of Runtime PM when/where needed and where a power domain is defined in devicetree. Function mtk_clk_register_gates() then becomes a wrapper around the new mtk_clk_register_gates_with_dev() function that will simply pass NULL as struct device: this is essential when registering drivers with CLK_OF_DECLARE instead of as a platform device, as there will be no struct device to pass... but we can as well simply have only one function that always takes such pointer as a param and pass NULL when unavoidable. This commit removes the mtk_clk_register_gates() wrapper and renames mtk_clk_register_gates_with_dev() to the former and all of the calls to either of the two functions were fixed in all drivers in order to reflect this change; also, to improve consistency with other kernel functions, the pointer to struct device was moved as the first param. Since a lot of MediaTek clock drivers are actually registering as a platform device, but were still registering the mtk-gate clocks without passing any struct device to the clock framework, they've been changed to pass a valid one now, as to make all those platforms able to use runtime power management where available. While at it, some much needed indentation changes were also done.

clk: mediatek: Replace 'struct clk' with 'struct clk_hw' As part of the effort to improve the MediaTek clk drivers, the next step is to switch from the old 'struct clk' clk prodivder APIs to the new 'struct clk_hw' ones. Instead of adding new APIs to the MediaTek clk driver library mirroring the existing ones, moving all drivers to the new APIs, and then removing the old ones, just migrate everything at the same time. This involves replacing 'struct clk' with 'struct clk_hw', and 'struct clk_onecell_data' with 'struct clk_hw_onecell_data', and fixing up all usages. For now, the clk_register() and co. usage is retained, with __clk_get_hw() and (struct clk_hw *)->clk used to bridge the difference between the APIs. These will be replaced in subsequent patches.
