clk: meson: enable building as modules

2020-11-23T08:08:23Z

Make it possible to build all clk drivers as modules, but default remains built-in. No functional changes. Signed-off-by: Kevin Hilman Signed-off-by: Jerome Brunet Acked-by: Stephen Boyd Link: https://lore.kernel.org/r/20201118191405.36798-1-khilman@baylibre.com

clk: meson: Kconfig: fix dependency for G12A

2020-11-23T08:08:22Z

When building only G12A, ensure that VID_PLL_DIV clock driver is selected, otherwise results in this build error: ERROR: modpost: "meson_vid_pll_div_ro_ops" [drivers/clk/meson/g12a.ko] undefined!

clk: meson: make shipped controller configurable

2020-09-10T09:47:33Z

Add the necessary bits so unnecessary amlogic clock controllers can be compiled out. This allows to save a few kB when necessary. Signed-off-by: Jerome Brunet Reviewed-by: Stephen Boyd Link: https://lore.kernel.org/r/20200828154735.435374-1-jbrunet@baylibre.com

clk: meson: add g12a cpu dynamic divider driver

2019-08-09T10:10:03Z

Add a clock driver for the cpu dynamic divider, this divider needs to have a flag set before setting the divider value then removed while writing the new value to the register. This drivers implements this behavior and will be used essentially on the Amlogic G12A and G12B SoCs for cpu clock trees.

clk: meson: remove clk input helper

2019-07-29T10:42:49Z

The clk input function which allows clock controllers to register a bypass clock from a clock producer is no longer needed anymore since meson clock controllers have migrated to a new parent allocation method. Signed-off-by: Alexandre Mergnat Signed-off-by: Jerome Brunet

clk: meson: remove ee input bypass clocks

2019-07-29T10:42:49Z

During probe, bypass clocks (i.e. ee-in-xtal) are made from device-tree inputs to provide input clocks which can be access through global name. The cons of this method are the duplicated clocks, means more string comparison. Specify parent directly with device-tree clock name. Remove the bypass clock registration from the ee probe function.

clk: meson: remove ao input bypass clocks

2019-07-29T10:42:48Z

During probe, bypass clocks (i.e. ao-in-xtal) are made from device-tree inputs to provide input clocks which can be access through global name. The cons of this method are the duplicated clocks, means more string comparison. Specify parent directly with device-tree clock name. Function to regiter bypass clocks is removed. Input parameters from meson aoclk data structure are deprecated and then deleted since all aoclk files are migrated. Signed-off-by: Alexandre Mergnat Signed-off-by: Jerome Brunet

clk: meson: axg-audio: migrate to the new parent description method

2019-07-29T10:42:48Z

This clock controller use the string comparison method to describe parent relation between the clocks, which is not optimized. A recent patch [0] allows parents to be specified without string names or with device-tree clock name by using a new assignment structure. Migrate to the new way by using .parent_hws where possible (when parent clocks are localy declared in the controller) and use .parent_data otherwise. Remove clk input helper and all bypass clocks (declared in probe function) which are no longer used since we are able to use device-tree clock name directly.
