Hi Krzysztof, Thanks for this patch. Please add my
Tested-by: Anand Moon <linux.am...@gmail.com> [snip] Could you integrate below small changes into this patch. with these below changes suspend and resume work correctly at my end. [1] XU4_suspendresume.patch As per S2MPS11B PMIC 1.2.1 Regulator (Features) Fix the min max value for *Buck7* and *Buck8* -- Buck7 (VDD_1.0V_LDO) 1.5 A (1.2 V to 1.5 V, 12.5 mV step, default on 1.35 V) -- Buck8 (VDD_1.8V_LDO) 2.5 A (1.8 V to 2.1 V, 12.5 mV step, default on 2.0 V) Also add suspend-off for *Buck9* Buck9 internally controls the power of USB hub. Adding suspend the this node help proper reset of USB hub on Odroid XU4 / HC1/ XU3 during suspend and resume. Below it the logs from my testing. [2] https://pastebin.com/pRJJmWL6 Best Regards -Anand
