<ssvb> plaes: look at the other LVDS configs in u-boot
<plaes> there aren't any
<plaes> hmm
<ssvb> plaes: I think only CONFIG_VIDEO_LCD_PANEL_LVDS=y is needed, see http://git.denx.de/?p=u-boot.git;a=commitdiff;h=213480e12d880ef6782f56f1af95469b48cca539
<ssvb> plaes: I think CONFIG_VIDEO_LCD_PANEL_HITACHI_TX18D42VM=y there selects LVDS too
<plaes> hrm.. it will be fun, figuring out the panel:S
<ssvb> plaes: maybe it is not necessary, it could be that only the hitachi panel is special and needs extra initialization
<ssvb> plaes: is your fex file available in sunxi-boards?
<plaes> the one that's android is using, is the identical
<plaes> and I have also tried sunxi-3.4 with that fex, so it works
<plaes> I assume there's something really wrong with the ri and up parameters I got from calculations
<ssvb> plaes: the script from http://linux-sunxi.org/LCD#Script_for_automated_conversion says that you need to use: CONFIG_VIDEO_LCD_MODE="x:1024,y:768,depth:18,pclk_khz:100000,le:799,ri:260,up:15,lo:16,hs:1,vs:1,sync:3,vmode:0"
<ssvb> plaes: how did you calculate them?
<plaes> wrong :P

<diego71> hi, anybody know how to use gpio in mainline kernel? Or how to map pin with the gpio number...
<plaes> servili007: yeah, this part should be rewritten someone with more knowledge
<plaes> diego71: did you search wiki?
<plaes> well, there are other pages too
<diego71> I want to read from pin 9 (pb2)
<plaes> and on one specific page there's section called: "Accessing the GPIO pins through sysfs with mainline kernel"
akaizen has joined #linux-sunxi
<diego71> plaes: perfect, it's what i needed. Thanks
<plaes> :)
<plaes> so you found the page titled "GPIO"? ;)
ricardocrudo has joined #linux-sunxi
<plaes> apparently this parallel thingy was not really required
akaizen has quit [Ping timeout: 240 seconds]
<diego71> plaes: I take a quick look first, but I missed the "mainline kernel" section, and I only saw the 3.4 O:-)
<plaes> yeah.. we should start fixing the pages to deprecate sunxi-3.4 info

<Turl> ssvb: I'm not understanding what you're saying
<Turl> nm I'm reading the diff backwards
<Turl> so lvds is supported? :)

<Turl> ssvb: git://git.denx.de/u-boot.git -b master ?
