clock-controller@fdd00000: 'rockchip,grf', 'rockchip,pmugrf' do not
match any of the regexes: 'pinctrl-[0-9]+'

Currently clk.c has only support for:

ctx->grf = syscon_regmap_lookup_by_phandle(ctx->cru_node,
"rockchip,grf");

Manufacturer tree:

ctx->pmugrf = syscon_regmap_lookup_by_phandle(ctx->cru_node,
"rockchip,pmugrf");
case branch_muxpmugrf:
clk = rockchip_clk_register_muxgrf(list->name,
list->parent_names, list->num_parents,
flags, ctx->pmugrf, list->muxdiv_offset,
list->mux_shift, list->mux_width,
list->mux_flags);
break;

MUXPMUGRF(SCLK_32K_IOE, "clk_32k_ioe", clk_32k_ioe_p, 0,
RK3568_PMU_GRF_SOC_CON0, 0, 1, MFLAGS)

Do we need a fix?

clock-controller@fdd20000: 'assigned-clock-parents',
'assigned-clock-rates', 'assigned-clocks', 'rockchip,grf' do not match
any of the regexes:

Add more properties to rockchip,rk3568-cru.yaml
