Update ov5640 autofocus related patch. We had it working with Martijn's patch in 5.9.1_git20201019-r2 (MR 1654), but then dropped the patch in favor of the patch that was added to megi's tree in 5.9.3_git20201101 (MR 1678). It turns out that the patch added to megi's tree was different than the patch we were carrying, it was a WIP version where loading the autofocus firmware did not work anymore. Megi decided to drop the autofocus patch from his tree for now, as the firmware uploader takes more time in Martijn's proper patch. According to Martijn it takes about a second, which seems reasonable for the postmarketOS use case. I've added the previous version again as out-of-tree patch. Martijn found that for some reason the continuous autofocus still doesn't want to start with this kernel and current patch version, as for some reason the firmware load fails. But he extended the patch to make autofocus work again with "tap to focus" at least. 0005-dts-pinephone-Disable-flash-led-in-OV5640-node.patch is not needed anymore, the same change is in megi's tree.

Subject: [PATCH] Disable 8723cs power saving
|
|
|
|
The runtime power management features in the 8723cs firmware on the
|
|
PinePhone don't seem to work correctly. While we expect the chipset to
|
|
leave a low power state when it's time to send or receive data, instead
|
|
we get a delay of 10-20 seconds before any packets are sent.
