Subject: Re: [Linux-fbdev-devel] [PATCH] atmel_lcdfb: wiring BGR to RGB colormode

Nicolas Ferre :
> Adds different wiring mode for the LCD screen.
> 
> The legacy atmel LCDC IP uses a non standard color mode,
> "BGR-555.1" instead "RGB-565". The major part of graphic stacks 
> for embedded systems uses only "RGB-565". It is possible to swap 
> LCD IOs instead of doing this bit swapping by software (See 
> application note AT91SAM9 LCD Controller
> http://www.atmel.com/dyn/resources/prod_documents/doc6300.pdf)
> 
> This wire swapping is done on the at91sam9rl-ek board (board code 
> using this patch will come later).
