clk: meson: s4: fix module autoloading

2024-05-03T12:27:32Z

Add MODULE_DEVICE_TABLE(), so modules could be properly autoloaded based on the alias from of_device_id table. Clocks are considered core components, so usually they are built-in, however these can be built and used as modules on some generic kernel.

clk: meson: g12a: make VCLK2 and ENCL clock path configurable by CCF

2024-04-10T07:46:21Z

In order to setup the DSI clock, let's make the unused VCLK2 clock path configuration via CCF. The nocache option is removed from following clocks: - vclk2_sel - vclk2_input - vclk2_div - vclk2 - vclk_div1 - vclk2_div2_en - vclk2_div4_en - vclk2_div6_en - vclk2_div12_en - vclk2_div2 - vclk2_div4 - vclk2_div6 - vclk2_div12 - cts_encl_sel vclk2 and vclk2_div uses the newly introduced vclk regmap driver to handle the enable and reset bits. In order to set a rate on cts_encl via the vclk2 clock path, the NO_REPARENT flag is set on cts_encl_sel & vclk2_sel in order to keep CCF from selection a parent. The parents of cts_encl_sel & vclk2_sel are expected to be defined in DT or manually set by the display driver at some point. The following clock scheme is to be used for DSI: xtal \_ gp0_pll_dco \_ gp0_pll |- vclk2_sel | \_ vclk2_input | \_ vclk2_div | \_ vclk2 | \_ vclk2_div1 | \_ cts_encl_sel | \_ cts_encl -> to VPU LCD Encoder |- mipi_dsi_pxclk_sel \_ mipi_dsi_pxclk_div \_ mipi_dsi_pxclk -> to DSI controller The mipi_dsi_pxclk_div is set as bypass with a single /1 entry in div_table in order to use the same GP0 for mipi_dsi_pxclk and vclk2_input. The SET_RATE_PARENT is only set on the mipi_dsi_pxclk_sel clock so the DSI bitclock is the reference base clock to calculate the vclk2_div value when pixel clock is set on the cts_encl endpoint.

clk: meson: add vclk driver

2024-04-10T07:46:21Z

The VCLK and VCLK_DIV clocks have supplementary bits. The VCLK gate has a "SOFT RESET" bit to toggle after the whole VCLK sub-tree rate has been set, this is implemented in the gate enable callback. The VCLK_DIV clocks as enable and reset bits used to disable and reset the divider, associated with CLK_SET_RATE_GATE it ensures the rate is set while the divider is disabled and in reset mode. The VCLK_DIV enable bit isn't implemented as a gate since it's part of the divider logic and vendor does this exact sequence to ensure the divider is correctly set.

clk: meson: pll: print out pll name when unable to lock it

2024-03-29T11:24:40Z

In most meson systems, multiple PLLs are present, making it difficult to identify the specific PLL that fails to lock. To address this issue, print out the name of the PLL that cannot be locked.
