Hi, I have now rebased our tree to v5.0-rc1. Was not very difficult. Just 3 or 4 almost obvious minor merge conflicts.
Unfortunately there is always something broken afterwards...
This time it is the display of the GTA04 :( Backlight works and can be controlled by "xset dpms" but the panel shows all white pixels. Pyra and BeagleBoneBlack + LCD both work this time.
Some first observations from initial tests:
- Pyra: bluetooth uart does not respond (wifi works)
- GTA04A4: backlight ok, display shows white pixels only
hmm, did a quick test with mainline: older dtb + 5.1-rc1 kernel = display ok 5.1-rc1 kernel + dtb-5-1-rc1 (both mainline) = black screen
Interesting. I did this:
iMac:master hns$ git diff letux-5.0 letux-5.1-rc1 -- arch/arm/boot/dts/omap3-gta04.dtsi iMac:master hns$ git diff letux-5.0 letux-5.1-rc1 -- arch/arm/boot/dts/omap3-gta04a4.dts iMac:master hns$ git diff letux-5.0 letux-5.1-rc1 -- arch/arm/boot/dts/omap3.dts iMac:master hns$ git diff letux-5.0 letux-5.1-rc1 -- arch/arm/boot/dts/omap36xx.dts iMac:master hns$
So there are no obvious differences between dts...
I think we have to use the dtc to disassemble the binaries (sorted by node) and then diff.
Hm...
Unless I did something wrong, the diff is empty!? Even the binaries do match:
iMac:master hns$ ls -l build/letux-5.0/device-trees/omap3-gta04a4.dtb -rw-r--r-- 1 hns staff 71513 8 Mär 21:35 build/letux-5.0/device-trees/omap3-gta04a4.dtb iMac:master hns$ ls -l build/letux-5.1-rc1/device-trees/omap3-gta04a4.dtb -rw-r--r-- 1 hns staff 71513 18 Mär 20:10 build/letux-5.1-rc1/device-trees/omap3-gta04a4.dtb iMac:master hns$ diff build/letux-5.0/device-trees/omap3-gta04a4.dtb build/letux-5.1-rc1/device-trees/omap3-gta04a4.dtb iMac:master hns$
Strange.
