Use clk_bulk APIs, and also add error handling for clk enable.

- clk = of_clk_get(node, i);
- if (IS_ERR(clk)) {
- error = PTR_ERR(clk);
+ pd->num_clks = of_count_phandle_with_args(node, "clocks",
+ "#clock-cells");

+ pd->clks = devm_kzalloc(pmu->dev, pd->num_clks * sizeof(pd->clks[0]),

This doesn't work for rk3399, as the pd_vio doesn't have any clocks
attached.

[ 0.713241] rockchip-pm-domain ff310000.power-management:power-controller: failed to handle node pd_vio: -12
[ 0.714615] rockchip-pm-domain: probe of ff310000.power-management:power-controller failed with error -12


I think Jeffy's v2 is coming, so I assume you will drop this version?



applied for 4.17, after changing to devm_kcalloc like below:

pd->clks = devm_kcalloc(pmu->dev, pd->num_clks, sizeof(*pd->clks),


Thanks
Heiko
