[U-Boot] [PATCH] sunxi: Add generic defconfigs for A33 Q8 tablets with 1024x600 / 800x480 LCD
The 7" Q8 tablet enclosure is used for a ton of slightly different cheap chinese tablets. There are some differences in which accelerometer / wifi is used, but other then that these are all the same from a u-boot / kernel pov.
When we get to adding accelerometer support the plan is to add some kind of autodetection and mangle the dt accordingly (likely using the new quirks mechanism).
For now this is a non issue as we do not yet have accelerometer support, and in the future, some sort of auto-detect is the way to go as we cannot expect users to exactly know what is inside their tablet.
The dts[i] files this commit adds are indentical to the ones submitted to the upstream kernel.

Yes, there are multiple modelines floating around for 800x480 panels, I've 2 A13 tablets and the modeline of the fex file from tablet a causes the images to not be properly centered on the screen of tablet b. Luckily the other way around does work, so for the q8_a13_tablet_defconfig I'm using the modeline from the fex file from tablet b. I hope we can do something similar with q8 a23 and a33 800x480 tablets.
I've been buying q8 tablets with cracked screens (people seem to drop them quite a lot) for cheap from a local 2nd hand website, so now I've 5 ever so slightly different models, I still need to make a generic q8 config for those, and see if I can find a modeline which works on all of them.
That modeline should probably be a good one to use for the a33 defconfig too.
I'll find some time to give yours a test.
Thanks!

Hans

I've been buying q8 tablets with cracked screens
To be clear s/screen/digitizer/ aka touchscreen, it usually is almost always the touchscreen which gets cracked and replacing that costs 4 usd (and half an hour of work).

So it looks like your modeline works as well. I can't see any difference between the two on screen. Speaking of the screen, mine is slightly off vertically. Feels like it is 1 line lower than it should be. And the right most end displays partially under the touchscreen with either modeline.

Great, thanks for testing this.

Yeah I've this with some other q8 tablets too, where the black bezel of the touchscreen slightly overlaps part of the lcd which should be visible, I guess this can be expected given the prices of these tablets.
