After that, we can enable only necessary clock here. Otherwise system will halt and block the other part upstream. > >> @@ -309,12 +316,20 @@ struct clk *imx_clk_pllv3(enum imx_pllv3_type type, const char *name, >> case IMX_PLLV3_ENET: >> ops = &clk_pllv3_enet_ops; >> break; >> + case IMX_PLLV3_SYSV2: >> + ops = &clk_pllv3_ops; >> + break; >> default: >> ops = &clk_pllv3_ops; >> } >> pll->base = base; >> pll->div_mask = div_mask; >> >> + if (cpu_is_imx7d() && strcmp(name, "pll_enet_main") == 0) >> + pll->powerdown = ENET_PLL_POWER; >> + else >> + pll->powerdown = BM_PLL_POWER; > > You should probably add a new PLL type, like IMX_PLLV3_ENET_IMX7 or such > instead of using cpu_is_ and strcmp.
