The earlier patch with commit id and title below: 5a6d3d1fbca70d7f528c685292d64c4cd0106aa6 board: roc-pc-rk3399: Add support for onboard LED's and push button to indicate power mode introduced a scenario where, if the device is in a remote location and rebooted, then human intervention is required to press the Power key/push button. The patch[0] is the fix for the reboot scenario. But as pointed out by Markus Reichl, if there is a power outage/interruption, still human intervention is required to press the Power key/push button, and as result markus suggested for a straight boot without human intervention in all cases. (http://lists.infradead.org/pipermail/linux-rockchip/2020-April/030224.html) This patch does a straight boot without human intervention in all cases. so, patch[0], patch[1], patch[2], patch[3] are not required. patch[1]: https://patchwork.ozlabs.org/patch/1258095/ patch[2]: https://patchwork.ozlabs.org/patch/1258096/ patch[3]: https://patchwork.ozlabs.org/patch/1258097/ Thanks Suniel > > > Thanks, > > - Kever > > [0] https://patchwork.ozlabs.org/patch/1258094/ > > On 2020/4/2 ??8:52, sunil at amarulasolutions.com wrote: > > From: Suniel Mahesh <sunil at amarulasolutions.com> > > In case of a power interruption, human intervention is required which > is not desirable if the device is installed at a remote location.
