Subject: colibri-pxa300: LCD_LDD / LCD_CS gpio conflict
Date: Mon, 6 Sep 2010 15:12:23 +0200 [thread overview]
Message-ID: <201009061512.23705.pieterg@gmx.com> (raw)
In colibri-pxa300.c, line 132, gpio config GPIO62_LCD_CS_N is overriding the
GPIO62_LCD_LDD_8 configuration, earlier in the pin config table.
As a result, one pixel data line is missing, obviously causing wrong pixel
data on passive lcd panels.
Not sure what the best workaround should be.
LDD_CS is not available on the colibri evalboard as far as I can see, so we
might just define GPIO127_LCD_CS_N instead? (till the soc/carrier board
configs have been split)
Or for now just put GPIO62_LCD_CS_N between
#ifdef CONFIG_FB_PXA_SMARTPANEL?
Rgds, Pieter
