2019-04-11clk: mediatek: Add configurable pcw_chg_reg to mtk_pll_dataWeiyi Lu1-0/+1
In previous MediaTek PLL design, it assumes the pcw change control is always on the CON1 register. However, the pcw change bit on MT8183 was moved onto CON0 because the the PCW length of audio PLLs are extended to 32-bit. Add configurable pcw_chg_reg to set the pcw change control register address or using the default control register CON1 if without setting in pll data.

2018-01-10clk: mediatek: adjust dependency of reset.c to avoid unexpectedly being builtSean Wang1-7/+0
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.

2017-12-26clk: mediatek: Fix all warnings for missing struct clk_onecell_dataSean Wang1-0/+1
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.

2015-05-05clk: mediatek: Add reset controller supportSascha Hauer1-0/+10
The pericfg and infracfg units also provide reset lines to several other SoC internal units. This adds a function which can be called from the pericfg and infracfg initialization functions which will register the reset controller using reset_controller_register. The reset controller will provide support for resetting the units connected to the pericfg and infracfg controller. The units resetted by this controller can use the standard reset device tree binding to gain access to the reset lines.
