The driver will still support #power-domain-cells = <0>, thus, previous users are not affected. The #power-domain-cells = <1> has been instantiated only for RZ/G3S at the moment as individual platform clock drivers need to be adapted for this to be supported on the rest of the SoCs.

This is done through MSTOP-specific registers that are part of CPG. Each individual module has one or more bits associated with one MSTOP register (see table "Registers for Module Standby Mode" from HW manuals). Hardware manual associates modules' clocks with one or more MSTOP bits. There are 3 mappings available (identified by researching RZ/G2L, RZ/G3S, RZ/V2L HW manuals): case 1: N clocks mapped to N MSTOP bits (with N={0, ..., X}) case 2: N clocks mapped to 1 MSTOP bit (with N={0, ..., X}) case 3: N clocks mapped to M MSTOP bits (with N={0, ..., X}, M={0, ..., Y}) Case 3 has been currently identified on RZ/V2L for the VCPL4 module. To cover all three cases, the individual platform drivers will provide to clock driver MSTOP register offset and associated bits in this register as a bitmask and the clock driver will apply this bitmask to proper MSTOP register. The MSTOP was implemented through power domains. Platform-specific clock drivers will register an array of type struct rzg2l_cpg_pm_domain_init_data, which will be used to instantiate properly the power domains.

Signed-off-by: Claudiu Beznea Reviewed-by: Geert Uytterhoeven --- Changes in v4: - dropped DEF_REG_CONF() specific to pwrdn functionality - dropped ddr, tzcddr, oftde_ddr domains as these were there due to the pwrdn functionality - added wdt0 domain; this will not impact currently integrated watchdog support - @Geert: I dropped your previous Rb tag due to the changes in v4 Changes in v3: - collected tags Change in v2: - used DEF_REG_CONF() to describe register offests and bits - updated MSTOP bitmask for ddr domain - updated MSTOP config for oftde_ddr - kept the same description for gic as the CPG_BUS_ACPU_MSTOP register documentation in the latest HW manual version is wrong and it will be fixed; proper description for GIC is located in "Registers for Module Standby Mode" table - haven't added watchdog domain (was missing in v1, too, by mistake) as the watchdog restart handler will fail w/o patch [1]; with this pm domain support the watchdog will fail to probe; not sure what is the best option until [1] will be integrated [1] https://patchwork.kernel.org/project/linux-renesas-soc/patch/20240228083253.2640997-10-claudiu.beznea.uj@bp.renesas.com drivers/clk/renesas/r9a08g045-cpg.c | 41 +++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) diff --git a/drivers/clk/renesas/r9a08g045-cpg.c b/drivers/clk/renesas/r9a08g045-cpg.c index c3e6da2de197..b068733b145f 100644 --- a/drivers/clk/renesas/r9a08g045-cpg.c +++ b/drivers/clk/renesas/r9a08g045-cpg.c @@ -240,6 +240,43 @@ static const unsigned int r9a08g045_crit_mod_clks[] __initconst = { MOD_CLK_BASE + R9A08G045_DMAC_ACLK, };
