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:

Lots of clock drivers have got both .probe() and a .remove() callbacks: switch from builtin_platform_driver() to module_platform_driver() so that we actually register the .remove() callback. Signed-off-by:

Convert this driver to use the common mtk_clk_simple_probe() mechanism. While at it, also remove __initconst annotations (as these structures are used also at runtime). Signed-off-by:

Convert this driver to use the common mtk_clk_simple_probe() mechanism. While at it, also use module_platform_driver() instead, as this driver just gained a .remove() callback during the conversion. Signed-off-by:

In preparation for migrating mt8516 clocks to the common simple probe mechanism, convert the apmixedsys to be a separated platform driver and move it to clk-mt8516-apmixedsys.c. While at it, also fix some indentation issues. During the conversion, error handling was added to the apmixedsys probe function. Signed-off-by:

Convert the MT7622 topckgen and pericfg clock drivers to platform drivers and use the simple probe mechanism. This also allows to build these clocks as modules. Thanks to the conversion, more error handling was added to the clocks registration. 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. While at it, also convert it to be a platform driver instead; to do so, also add a .remove() callback for this driver. During the conversion, error handling was added to the infracfg probe function.

In preparation for migrating mt7622 clocks to the common simple probe mechanism, move apmixedsys clocks to a different file. While at it, use the builtin_platform_driver() macro for it. During the conversion, error handling was added to the apmixedsys probe function. Signed-off-by:

Instead of calling clk_prepare_enable() for clocks that shall stay enabled, use the CLK_IS_CRITICAL flag, which purpose is exactly that. Fixes: 2fc0a509 ("clk: mediatek: add clock support for MT7622 SoC") Signed-off-by:

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). Change all clock drivers to always and consistently use this macro. Signed-off-by:

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: -

Convert topckgen and infracfg clock drivers to use the common mtk_clk_simple_probe() mechanism and change this from the old "static" CLK_OF_DECLARE to be a platform driver, allowing it to eventually be built as a module.

In preparation for converting the MT8167 clock drivers to be proper platform_driver(s), drop the __initconst annotation from all of the clock arrays since they will be used not only during init but also during runtime. Signed-off-by:

In preparation for migrating this driver to the simple probe mechanism, join the audio gates to the top_misc_mux_gates array of mtk_composite clocks in one top_misc_muxes array. While at it, since the `apll_i2s0_parents` array is for all i2s clocks, rename that to `apll_i2s_parents`. Signed-off-by:

On this SoC some clocks apparently don't have different offsets for set/clr/sta registers hence they can be set, cleared and status-read on one register: this means that it was possible to use simpler gate clocks instead of custom mtk_gate ones. In preparation for converting this clock driver to the common probe mechanism for MediaTek clocks, perform a conversion from simple_gate to mtk_gate clocks since the latter does provide implicit support for simple gate clocks as well.

Now that all of the clocks in clk-mt2712.c are using the common mtk_clk_simple_{probe,remove}() callbacks we can safely migrate to module_platform_driver. While at it, also drop all references to `simple` in the specific context of mt2712 as that was used in the past only to allow us to have two platform_driver(s) in one file. Signed-off-by: -

Now that the common mtk_clk_simple_{probe,remove}() functions can deal with divider clocks it is possible to migrate more clock drivers to it: in this case, it's about topckgen.

Reduce duplication and simplify all MediaTek multimedia clock drivers by migrating away from defining custom probe functions for each driver and instead use mtk_clk_pdev_probe(). While at it, also add a .remove() callback to all of the multimedia clock drivers where missing. Signed-off-by:
-
AngeloGioacchino Del Regno authored
Introduce functions clk_mtk_pdev_probe() and clk_mtk_pdev_remove(): these will be useful to commonize the probe and remove handlers for multimedia (clk-mtxxxx-mm) drivers as these are registered by the mtk-mmsys driver instead of having their own devicetree compatible. In order to do this, the main logic of clk_mtk_simple{probe,remove}() was moved to new static __clk_mtk_simple_{probe,remove}() functions that take as parameter a pointer to struct device_node because when registering the clocks from mtk-mmsys we want to pass a pointer to the clock driver's parent (which is, obviously, mtk-mmsys) struct device_node instead. As for the clock driver's platform data: for the devicetree case, we keep using the standard match_data mechanism, else we retrieve it from an id_table. Signed-off-by: -
