Changes in v6: - As Russell suggestion, detect whether of_reset_control_get() failed - add the comment for 1ms delay. Series-changes: 5 - back to v2 cpu on/off flow, As Heiko point out in patch v3. - delay more time in rockchip_boot_secondary(). From CPU up/down tests, Needed more time to complete CPU process. In order to ensure a more, Here that be delayed 1ms. Series-changes: 4 - Add reset_control_put(rstc) for the non-error case. Series-changes: 3 - FIx the PATCH v2, it doesn't work on chromium 3.14. Series-changes: 2 - As Heiko suggestion, re-adjust the cpu on/off flow. CPU off: reset_control_assert regmap_update_bits(pmu, PMU_PWRDN_CON, BIT(pd), BIT(pd)) wait_for_power_domain_to_turn_off CPU on: regmap_update_bits(pmu, PMU_PWRDN_CON, BIT(pd), 0) wait_for_power_domain_to_turn_on reset_control_deassert - Fix the delay 1ms describing. Series-changes: 5 - Fix the patch decription. - Add the changelog. Series-changes: 2 - As Kever points out, Fix the subject typo WFI/WFE. - fix the commnet Unified format. Series-changes: 5 - Add the changelog. Series-changes: 2 - Use the checkpatch.pl -f --subjective to check.
