2023-07-19clk: Explicitly include correct DT includesRob Herring1-2/+0
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-06-13clk: mediatek: Remove CLK_SET_PARENT from all MSDC core clocksAngeloGioacchino Del Regno1-9/+9
Various MSDC core clocks, used for multiple MSDC controller instances, share the same parent(s): in order to add parents selection in the mtk-sd driver to achieve an accurate clock rate for all modes, remove the CLK_SET_RATE_PARENT flag from all MSDC clocks for all SoCs: this will make sure that a clk_set_rate() call performed for a clock on a secondary controller will not change the rate of a common parent, which would result in an overclock or underclock of one of the controllers.

The clk-mux driver was forcing the CLK_SET_RATE_PARENT flag even for the GATE_CLK_SET_UPD_FLAGS() macro, as in mtk_clk_register_mux() the flag was unconditionally added. In preparation for a change on MSDC clock muxes, stop forcing this flag and, where necessary, update clock drivers to add it so that with this commit we introduce no functional changes for the currently supported SoCs.

__mtk_clk_simple_remove() and so also mtk_clk_simple_remove() return zero unconditionally. Make them return no value instead and convert the drivers making use of it to platform_driver's .remove_new(). This makes the semantics in the callers of mtk_clk_simple_remove() clearer and prepares for the quest to make platform driver's remove function return void. There is no semantic change.

2023-01-31clk: mediatek: clk-gate: Propagate struct device with mtk_clk_register_gates()AngeloGioacchino Del Regno1-3/+3
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.

2022-05-20clk: mediatek: Replace 'struct clk' with 'struct clk_hw'Chen-Yu Tsai1-6/+6
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. Fix up mtk_{alloc,free}_clk_data to use 'struct clk_hw' by hand. Fix up all other affected call sites with the following coccinelle script. // Replace type @@ @@ - struct clk_onecell_data + struct clk_hw_onecell_data // Replace of_clk_add_provider() & of_clk_src_simple_get() @@ expression NP, DATA; symbol of_clk_src_onecell_get; @@ - of_clk_add_provider( + of_clk_add_hw_provider( NP, - of_clk_src_onecell_get, + of_clk_hw_onecell_get, DATA ) // Fix register/unregister @@ identifier CD; expression E; identifier fn =~ "unregister"; @@ fn(..., - CD->clks[E] + CD->hws[E]->clk ,... ); // Fix calls to clk_prepare_enable() @@ identifier CD; expression E; @@ clk_prepare_enable( - CD->clks[E] + CD->hws[E]->clk ); // Fix pointer assignment @@ identifier CD; identifier CLK; expression E; @@ - CD->clks[E] + CD->hws[E] = ( - CLK + __clk_get_hw(CLK) | ERR_PTR(...) ) ; // Fix pointer usage @@ identifier CD; expression E; @@ - CD->clks[E] + CD->hws[E] // Fix mtk_clk_pll_get_base() @@ symbol clk, hw, data; @@ mtk_clk_pll_get_base( - struct clk *clk, + struct clk_hw *hw, const struct mtk_pll_data *data ) { - struct clk_hw *hw = __clk_get_hw(clk); ... } // Fix mtk_clk_pll_get_base() usage @@ identifier CD; expression E; @@ mtk_clk_pll_get_base( - CD->clks[E] + CD->hws[E]->clk ,... ); Signed-off-by: Chen-Yu Tsai <wenst@chromium.org> Reviewed-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Reviewed-by: Miles Chen <miles.chen@mediatek.com> Tested-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Tested-by: Miles Chen <miles.chen@mediatek.com> Link: https://lore.kernel.org/r/20220519071610.423372-4-wenst@chromium.org Signed-off-by: Stephen Boyd <sboyd@kernel.org>

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.
