* [PATCH 0/1] ARM: dts: sunxi: Add simplefb nodes for de_be0-lcd0, de_be0-lcd0-tve0 @ 2014-12-27 16:08 ` Hans de Goede 0 siblings, 0 replies; 6+ messages in thread From: Hans de Goede @ 2014-12-27 16:08 UTC (permalink / raw) To: linux-arm-kernel Hi Maxime, As you may have noticed on the u-boot list, I've been working on adding support for getting a graphical u-boot console up on sunxi LCD and VGA outputs. The main reason behind this is so that people can see u-boot (error) messages without needing to solder a serial console onto tablets (and other boards), hopefully we will get otg support in the near future too, and then people can interact with upstream u-boot without needing to open their tablet. Getting the kernel to work with LCD / VGA output setup by u-boot requires adding pre-populated simplefb nodes for a display pipeline of de_be0-lcd0 (for LCD) resp. de_be0-lcd0-tve0 (for VGA), this patch adds the necessary nodes. With this patch the kernel can use LCD / VGA outputs setup by u-boot. LCD output has been tested on various Olinuxino boards with the 7" Olimex LCD module, and on a 7" LCD of an A23 tablet, it has also been successfully tested by both ChenYu and Siarhei on other tablets. VGA output has been tested on a Cubietruck, A20-Olinuxino-Micro and a Mele-M3. Regards, Hans ^ permalink raw reply [flat|nested] 6+ messages in thread
