clk: mediatek: fix PWM clock source by adding a fixed-factor clock

2018-03-19T20:25:30+00:00

The clock for which all PWM devices on MT7623 or MT2701 actually depending on has to be divided by four from its parent clock axi_sel in the clock path prior to PWM devices. Consequently, adding a fixed-factor clock axisel_d4 as one-fourth of clock axi_sel allows that PWM devices can have the correct resolution calculation.

clk: mediatek: adjust dependency of reset.c to avoid unexpectedly being built

2018-01-10T21:41:15+00:00

Changes from v1->v2: Add 'select RESET_CONTROLLER' under COMMON_CLK_MEDIATEK and enable reset.c to be built when COMMON_CLK_MEDIATEK is selected. That should be quite reasonable because the reset controller is tightly embedded inside and exported from these clock subsystems. At least it can be found on infracfg and pericfg subsystem that both are really fundamental block lots of devices must depend on. commit 74cb0d6dde8 ("clk: mediatek: fixup test-building of MediaTek clock drivers") can let the build system looking into the directory where the clock drivers resides and then allow test-building the drivers. But the change also gives rise to certain incorrect behavior which is reset.c being built even not depending on either COMPILE_TEST or ARCH_MEDIATEK alternative dependency. To get rid of reset.c being built unexpectedly on the other platforms, it would be a good change that the file should be built depending on its own specific configuration rather than just on generic RESET_CONTROLLER one.

clk: mediatek: Fix all warnings for missing struct clk_onecell_data

2017-12-27T01:15:36+00:00

Even though the header file linux/clk-provider.h is already being properly included in clk-mtk.h, the definition of struct clk_onecell_data still must depend on CONFIG_COMMON_CLK defined and thus it's possible that below build warnings occur when CONFIG_COMMON_CLK is not being selected. Therefore, these functions which need struct clk_onecell_data without declaring that structure first requires simply declaring that this struct exists prior to referencing it in clk-mtk.h Changes from v1->v2: enhance v1 based on two useful solutions Jean Delvare kindly suggested. All warnings (new ones prefixed by >>): In file included from drivers/clk/mediatek/reset.c:22:0: >>drivers/clk/mediatek/clk-mtk.h:44:19: warning: 'struct clk_onecell_data' declared inside parameter list will not be visible outside of this definition or declaration int num, struct clk_onecell_data *clk_data); ^~~~~~~~~~~~~~~~ drivers/clk/mediatek/clk-mtk.h:63:19: warning: 'struct clk_onecell_data' declared inside parameter list will not be visible outside of this definition or declaration int num, struct clk_onecell_data *clk_data); ^~~~~~~~~~~~~~~~ drivers/clk/mediatek/clk-mtk.h:145:10: warning: 'struct clk_onecell_data' declared inside parameter list will not be visible outside of this definition or declaration struct clk_onecell_data *clk_data); ^~~~~~~~~~~~~~~~ drivers/clk/mediatek/clk-mtk.h:164:11: warning: 'struct clk_onecell_data' declared inside parameter list will not be visible outside of this definition or declaration struct clk_onecell_data *clk_data); ^~~~~~~~~~~~~~~~ drivers/clk/mediatek/clk-mtk.h:190:12: warning: 'struct clk_onecell_data' declared inside parameter list will not be visible outside of this definition or declaration struct clk_onecell_data *clk_data); ^~~~~~~~~~~~~~~~ Reported-by: kbuild test robot Signed-off-by: Sean Wang Cc: kbuild-all@01.org Cc: Stephen Boyd Cc: Jean Delvare Cc: linux-clk@vger.kernel.org Signed-off-by: Stephen Boyd

Pull clk updates from Stephen Boyd: "We have two changes to the core framework this time around. The first being a large change that introduces runtime PM support to the clk framework. Now we properly call runtime PM operations on the device providing a clk when the clk is in use. This helps on SoCs where the clks provided by a device need something to be powered on before using the clks, like power domains or regulators. It also helps power those things down when clks aren't in use. The other core change is a devm API addition for clk providers so we can get rid of a bunch of clk driver remove functions that are just doing of_clk_del_provider(). Outside of the core, we have the usual addition of clk drivers and smattering of non-critical fixes to existing drivers. The biggest diff is support for Mediatek MT2712 and MT7622 SoCs, but those patches really just add a bunch of data. By the way, we're trying something new here where we build the tree up with topic branches. We plan to work this into our workflow so that we don't step on each other's toes, and so the fixes branch can be merged on an as-needed basis.
