This re-hashes two older series I posted a long time ago, re-basing them to mainline. ...well, technically, atop another dwc2 series I recently posted: * usb: dwc2: Another attempt handling rk3288's remote wake quirk https://lkml.kernel.org/r/20190416215351.242246-1-dianders@xxxxxxxxxxxx https://lore.kernel.org/patchwork/cover/1062972/ In general I've tried to add links to each patch pointing to relevant older discussion. Here are overall links to the cover letters though. Note that for the previous "allow wakeup" series the discussion was scattered a bit between the original post and the repost. * usb: dwc2: bus suspend/resume that's not hibernate https://lkml.kernel.org/r/1446237173-15263-1-git-send-email-dianders@xxxxxxxxxxxx https://lore.kernel.org/patchwork/patch/613761/ * dwc2 patches to allow wakeup on Rockchip rk3288 https://lkml.kernel.org/r/1435017144-2971-1-git-send-email-dianders@xxxxxxxxxxxx https://lore.kernel.org/patchwork/cover/572944/ * dwc2 patches to allow wakeup on Rockchip rk3288 (REPOST) https://lkml.kernel.org/r/1436207224-21849-1-git-send-email-dianders@xxxxxxxxxxxx https://lore.kernel.org/patchwork/cover/576120/ I'm hoping there's a better chance of these things landing this time around, but I guess we'll see. ;-) In case it's helpful I've put what I tested (which is based on Heiko's for-next branch and includes patches to enable deep suspend plus two other s2r fixes) at: https://chromium.googlesource.com/chromiumos/third_party/kernel/+log/refs/sandbox/dianders/190417-testing-dwc2-wakeup Changes in v2: - Rebased to mainline atop rk3288 remote wake quirk series. - rk3288-veyron dts patch new for v2.
