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. 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>
