From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx> Instantiate power domains for the currently enabled IPs of R9A08G045 SoC. Reviewed-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> Signed-off-by: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx> --- 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@xxxxxxxxxxxxxx drivers/clk/renesas/r9a08g045-cpg.c | 61 +++++++++++++++++++++++++++++ 1 file changed, 61 insertions(+) diff --git a/drivers/clk/renesas/r9a08g045-cpg.c b/drivers/clk/renesas/r9a08g045-cpg.c index c3e6da2de197..c64769082f5b 100644 --- a/drivers/clk/renesas/r9a08g045-cpg.c +++ b/drivers/clk/renesas/r9a08g045-cpg.c @@ -240,6 +240,62 @@ static const unsigned int r9a08g045_crit_mod_clks[] __initconst = { MOD_CLK_BASE + R9A08G045_DMAC_ACLK, }; +static const struct rzg2l_cpg_pm_domain_init_data r9a08g045_pm_domains[] = { + /* Keep always-on domain on the first position for proper domains registration. */ + DEF_PD("always-on", R9A08G045_PD_ALWAYS_ON, + DEF_REG_CONF(0, 0), + DEF_REG_CONF(0, 0), + RZG2L_PD_F_ALWAYS_ON), + DEF_PD("gic", R9A08G045_PD_GIC, + DEF_REG_CONF(CPG_BUS_ACPU_MSTOP, BIT(3)), + DEF_REG_CONF(CPG_PWRDN_IP1, BIT(2)), + RZG2L_PD_F_ALWAYS_ON), + DEF_PD("ia55", R9A08G045_PD_IA55, + DEF_REG_CONF(CPG_BUS_PERI_CPU_MSTOP, BIT(13)), + DEF_REG_CONF(CPG_PWRDN_IP1, BIT(3)), + RZG2L_PD_F_ALWAYS_ON), + DEF_PD("dmac", R9A08G045_PD_DMAC, + DEF_REG_CONF(CPG_BUS_REG1_MSTOP, GENMASK(3, 0)), + DEF_REG_CONF(0, 0), + RZG2L_PD_F_ALWAYS_ON), + DEF_PD("ddr", R9A08G045_PD_DDR, + DEF_REG_CONF(CPG_BUS_PERI_DDR_MSTOP, GENMASK(1, 0)), + DEF_REG_CONF(CPG_PWRDN_IP2, BIT(0)), + RZG2L_PD_F_ALWAYS_ON), + DEF_PD("tzcddr", R9A08G045_PD_TZCDDR, + DEF_REG_CONF(CPG_BUS_TZCDDR_MSTOP, GENMASK(2, 0)), + DEF_REG_CONF(CPG_PWRDN_IP2, BIT(1)), + RZG2L_PD_F_ALWAYS_ON), + DEF_PD("otfde_ddr", R9A08G045_PD_OTFDE_DDR, + DEF_REG_CONF(CPG_BUS_PERI_CPU2_MSTOP, BIT(2)), + DEF_REG_CONF(CPG_PWRDN_IP2, BIT(2)), + RZG2L_PD_F_ALWAYS_ON), + DEF_PD("sdhi0", R9A08G045_PD_SDHI0, + DEF_REG_CONF(CPG_BUS_PERI_COM_MSTOP, BIT(0)), + DEF_REG_CONF(CPG_PWRDN_IP1, BIT(13)), + RZG2L_PD_F_NONE), + DEF_PD("sdhi1", R9A08G045_PD_SDHI1, + DEF_REG_CONF(CPG_BUS_PERI_COM_MSTOP, BIT(1)), + DEF_REG_CONF(CPG_PWRDN_IP1, BIT(14)), + RZG2L_PD_F_NONE), + DEF_PD("sdhi2", R9A08G045_PD_SDHI2, + DEF_REG_CONF(CPG_BUS_PERI_COM_MSTOP, BIT(11)), + DEF_REG_CONF(CPG_PWRDN_IP1, BIT(15)), + RZG2L_PD_F_NONE), + DEF_PD("eth0", R9A08G045_PD_ETHER0, + DEF_REG_CONF(CPG_BUS_PERI_COM_MSTOP, BIT(2)), + DEF_REG_CONF(CPG_PWRDN_IP1, BIT(11)), + RZG2L_PD_F_NONE), + DEF_PD("eth1", R9A08G045_PD_ETHER1, + DEF_REG_CONF(CPG_BUS_PERI_COM_MSTOP, BIT(3)), + DEF_REG_CONF(CPG_PWRDN_IP1, BIT(12)), + RZG2L_PD_F_NONE), + DEF_PD("scif0", R9A08G045_PD_SCIF0, + DEF_REG_CONF(CPG_BUS_MCPU2_MSTOP, BIT(1)), + DEF_REG_CONF(0, 0), + RZG2L_PD_F_NONE), +}; + const struct rzg2l_cpg_info r9a08g045_cpg_info = { /* Core Clocks */ .core_clks = r9a08g045_core_clks, @@ -260,5 +316,10 @@ const struct rzg2l_cpg_info r9a08g045_cpg_info = { .resets = r9a08g045_resets, .num_resets = R9A08G045_VBAT_BRESETN + 1, /* Last reset ID + 1 */ + /* Power domains */ + .pm_domains = r9a08g045_pm_domains, + .num_pm_domains = ARRAY_SIZE(r9a08g045_pm_domains), + .pm_domain_pwrdn_mstop = true, + .has_clk_mon_regs = true, }; -- 2.39.2
