This patch adds support for Kaohsiung Opto-Electronics Inc. 10.1" TX26D202VM0BWA WUXGA(1920x1200) TFT LCD panel with LVDS interface. The panel has dual LVDS channels.
My panel is manufactured by US Micro Products(USMP). There is a tag at the back of the panel, which indicates the panel type is 'TX26D202VM0BWA' and it's made by KOE in Taiwan.
The panel spec from USMP can be found at: https://www.usmicroproducts.com/sites/default/files/datasheets/USMP-T101-192...
The below panel spec from KOE is basically the same to the one from USMP. However, the panel type 'TX26D202VM0BAA' is a little bit different. It looks that the two types of panel are compatible with each other. http://www.koe.j-display.com/upload/product/TX26D202VM0BAA.pdf

Sam, Thierry I assume you'll merge the series. Let me know if I should pick it up.
I am quite busy with non-linux stuff these days so fine if you can pick them up. I like that simple panel patches are processed fast.
I expect to have some hours for linux work friday or saturday, but no promises...
Don't worry - once the DT maintainers ack 1/2, I'll merge the series.
