Hi everyone,
I spent a bit of time adding DRM support for the A23 yesterday.
Icenowy successfully got DRM working for the A33 Q8 tablets.
It occurred to me today that we have 2 types of panels for the
A33 Q8 tablets, one is 800x480 and the other is 1024x600. However
we are currently sharing the same dts file for both, and only
U-boot knows about the different resolutions.
I see 2 ways to fix this. One would be to provide a separate
dts file for the 1024x600 variant. The other would be to get
U-boot to patch the dts file.
Either way would require users upgrading U-boot, or at least
their boot scripts in the first case, though.
Any ideas?
Since we already have 2 u-boot configs for this having 2 dts files
seems like the best solution to me.
Maybe for compatibility we need 3 dts files...
1. Q8 dts : everything except display (For users migrated from the old
single-dt time)
2. Q8 800x480 dts : #include <Q8 dts>, /panel/compatible = "urt,umsh-8596md-t"
/* This compatible is what Chen-Yu used in sun5i-q8, and I used it also on my
A33 Q8 */
3. Q8 1024x600 dts : #include <Q8 dts>, /panel/compatible = foo
Ah yes, I was wondering how to deal with older u-boot and
users then potentially getting the wrong panel setting.
This is much better.
Regards,
Hans
