[PATCH] i2c: designware: Re-init controllers with pm_disabled set on resume
Thank you for bringing this to our attention, I believe that this patch fixes this.
Thank you for the patch, I've just tested it on top of v4.18 in cold boot and reboot conditions doing several 'freeze'/wake up in a row and it fixes the problem. |
Created attachment 277943 [details] clear_i2c_poknirq Since v4.18, SOiX is working for my Meegopad T02 but when waking up, the irq for the power button is behaving stangely. 1/normal behaviour : power button press : 1 irq at axp20x-pek-dbf power button release : 1 irq at axp20x-pek-dbr 2/after wakeup by pressing power button: axp20x-pek-dbr increases by 1 axp20x-pek-dbf doesn't change 3/after freeze : power button press : 5000 irq/s at axp20x-pek-dbr, 0 irq at axp20x-pek-dbf power button release : nothing After 3, if I try to freeze, it wakes up immediatly. To stop the irq firing continuously I can unload/reload axp20x_pek module or clear the axp20x-pek-dbr interupt with i2cset. Then I can freeze and when it wakes up it is in the 2/ state. Note, that a long press (16s) to the power button halts the Meegopad T02, this behavior is not affected by the freeze.
