clk: renesas: r9a06g032: Probe possible children

2022-05-19T17:04:51+00:00

The clock controller device on r9a06g032 takes all the memory range that is described as being a system controller. This range contains many different (unrelated?) registers besides the ones belonging to the clock controller, that can necessitate to be accessed from other peripherals. For instance, the dmamux registers are there. The dmamux "device" will be described as a child node of the clock/system controller node, which means we need the top device driver (the clock controller driver in this case) to populate its children manually. In case of error when populating the children, we do not fail the probe on purpose to keep the clk driver up and running.

clk: renesas: r9a06g032: Export function to set dmamux

2022-05-19T17:04:51+00:00

The dmamux register is located within the system controller. Without syscon, we need an extra helper in order to give write access to this register to a dmamux driver.

clk: renesas: Add RZ/V2M support using the rzg2l driver

The Renesas RZ/V2M SoC is very similar to RZ/G2L, though it doesn't have any CLK_MON registers. Signed-off-by: Phil Edworthy Reviewed-by: Biju Das Link: https://lore.kernel.org/r/20220503115557.53370-11-phil.edworthy@renesas.com Signed-off-by: Geert Uytterhoeven

clk: renesas: rzg2l: Add support for RZ/V2M reset monitor reg

2022-05-05T10:12:33+00:00

The RZ/V2M doesn't have a matching set of reset monitor regs for each reset reg like the RZ/G2L. Instead, it has a single CPG_RST_MON reg which has a single bit per module.

clk: renesas: rzg2l: Set HIWORD mask for all mux and dividers

2022-05-05T10:12:32+00:00

All of the muxes and dividers that can be modified require the HIWORD flags, so make the macros set them. It won't affect read only muxes and dividers. This will make the clock tables a little easier to read, particularly for new SoCs coming.

clk: renesas: rzg2l: Move the DEF_MUX array size calc into the macro

2022-05-05T10:12:32+00:00

We only ever use ARRAY_SIZE() to populate the number of parents, so move this into the macro to always detect it automatically. This also makes the tables of clocks a little simpler. Similarly for the DEF_SD_MUX macro. Signed-off-by: Phil Edworthy Link: https://lore.kernel.org/r/20220503115557.53370-6-phil.edworthy@renesas.com Signed-off-by: Geert Uytterhoeven
