Just like in commit eddc6309 ("clk: mediatek: Ensure fhctl code is available for COMMON_CLK_MT6795"), these three need the shared driver code, otherwise they run into link errors such as: aarch64-linux/bin/aarch64-linux-ld: drivers/clk/mediatek/clk-mt8192-apmixedsys.o: in function `clk_mt8192_apmixed_probe': clk-mt8192-apmixedsys.c:(.text+0x134): undefined reference to `fhctl_parse_dt' Fixes: 45a5cbe0 ("clk: mediatek: mt8173: Add support for frequency hopping through FHCTL") Fixes: 4d586e10 ("clk: mediatek: mt8192: Add support for frequency hopping through FHCTL") Fixes: da4a82dc ("clk: mediatek: mt8195: Add support for frequency hopping through FHCTL") Signed-off-by:

Convert the MT8135 clock drivers to platform_driver using the common simple probe mechanism; special note goes to the introduction of dummy clocks with ID 0 (where 0 is the first entry of a clock array) for each clock controller: this was necessary because of a mistake in the bindings for all MT8135 clock controllers, where the first clock has ID 1 (hence, array would start from element 1) instead of zero. Now that all of the MT8135 clock drivers (including apmixedsys) can be compiled as modules, change the COMMON_CLK_MT8135 configuration option to tristate to enable module build. While at it, also remove the __initconst annotation from all of the clock arrays as they are not only used during init anymore, but also during runtime. Signed-off-by:

Bootloaders must in a way setup the SoC to boot Linux: this means that it will be possible to decompress a ramdisk and eventually insert the core clock driver module from there. Allow module build for all MT8192 clocks by switching to tristate. Signed-off-by:

This is the last man standing in clk-mt8192.c that won't allow us to use the module_platform_driver() macro, and for *no* good reason. Move it to clk-mt8192-apmixedsys.c and while at it, also add a .remove() callback for it. Also, since the need for "clk-mt8192-simple" and "clk-mt8192" was just due to them being in the same file and probing different clocks, and since now there's just one platform_driver struct per file, it seemed natural to rename the `-simple` variant to just "clk-mt8192".

When building clock drivers for MT8186, some may want to build in only some of them to, for example, get CPUFreq up faster, and some may want to leave out some clock drivers entirely as a machine may not need the Warp Engine or the camera ISP (hence, their clock drivers). Split the various clock drivers in their own configuration options, keeping MT8186 configuration options consistent with other MediaTek SoCs. While at it, also allow building the remaining clock drivers as modules by switching COMMON_CLK_MT8186 to tristate. Signed-off-by:

-
AngeloGioacchino Del Regno authored
MT8195 clock drivers were encapsulated in one single (and big) Kconfig option: there's no reason to do that, as it is totally unnecessary to build in all or none of them. Split them out: keep boot-critical clocks as bool and allow choosing non critical clocks as tristate. As a note, the dependencies of VDEC/VENCSYS and CAM/IMG/IPE/WPESYS are not for build-time but rather for runtime, as clocks registered by those have runtime dependencies on either or both VPP and IMGSYS.

In order to successfully build clock drivers as modules it is required to declare a module license: add it where missing. While at it, also change the MODULE_LICENSE text from "GPL v2" to "GPL" (which means the same) on clk-mt7981-eth.c. Signed-off-by:

The infracfg driver cannot be converted to clk_mtk_simple_probe() as it registers cpumuxes, which is not supported on the common probing mechanism: for this reason, move it to its own file.

All the various MediaTek clock drivers are, in a way or another, redefining the GATE_MTK() macro with different names: while some are doing that by actually using GATE_MTK(), others are copying it entirely (hence, entirely redefining it).

Switch to mtk_clk_simple_{probe,remove}() for infracfg and topckgen clocks on MT8183 to allow full module build for clock drivers. Differently from other MediaTek clock drivers, it was necessary to change the name of the `clk13m` clock, as that is already declared in the SoC's devicetree as a "fixed-factor-clock" (with the same name) and redeclaring it here would obviously fail to register the entire clock controller; this clock wasn't dropped only to retain compatibility with older devicetrees As a note, the `clk13m` clock is not mentioned in any parent names array(s) as the correct one (csw_f26m_d2) is already used in place of that. Thanks to the conversion, more error handling was added to the clocks registration. Signed-off-by: -
