2015-07-14video: vesa_fb: Look up VGA device by class instead of idBin Meng
Per PCI spec, VGA device reports its class as standard 030000h in its configuration space, so we can use it to determine if we need run option rom instead of testing the supported vendor/device ids. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

2015-05-04sunxi: Introduce a hidden SUNXI_GEN_SUNxI Kconfig boolHans de Goede
sun6i and newer (derived) SoCs such as the sun8i-a23, sun8i-a33 and sun9i have a various things in common, like having separate ahb reset control registers, the SID living inside the pmic, custom pmic busses, new style watchdog, etc. This commit introduces a new hidden SUNXI_GEN_SUN6I Kconfig bool which can be used to check for these features avoiding the need for an ever growing list of "#if defined CONFIG_MACH_SUN?I" conditionals as we add support for more "new style" sunxi SoCs. Note that this commit changes the behavior of the gmac and hdmi code for sun8i and the upcoming sun9i devices. This does not matter as sun8i does not have gmac nor hdmi, and sun9i has new hardware-blocks for these so the old code will not work there. Also this is intentional as if a sun8i / sun9i variant which does use the old hwblocks shows up then the GEN_SUN6I code paths will be the right ones to use. For completeness this also adds a SUNXI_GEN_SUN4I bool for A10/A13/A20. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

2015-03-05drivers/video/am335x-fb: Add possibility to wait for stable power/pictureHannes Petermaier
Often on boards exists a circuit which switches power on/off to LCD display. Due to the need of limiting the in-rush current the output voltage from this circuit rises "slowly", so it is necessary to wait a bit (VCC ramp up time) before starting output on LCD-pins. This time is specified in <n> ms within the panel-settings, called "pup_delay" Further some LCDs need a couple of frames to stabilize the image on it. We have now the possibility to wait some time after starting output on LCD. This time is also specified in <n> ms within panel-settings, called "pon_delay" Signed-off-by: Hannes Petermaier <oe5hpm@oevsv.at>

2015-02-16sunxi: video: Do not use CONFIG_SYS_MEM_TOP_HIDE for the framebufferHans de Goede
Do not use CONFIG_SYS_MEM_TOP_HIDE for the framebuffer, instead override board_get_usable_ram_top to make sure that u-boot is not relocated into the area where we want to use the framebuffer, and patch the devicetree from sunxi_simplefb_setup() to tell the kernel to not touch the framebuffer. This makes u-boot properly see the framebuffer as dram, and initalize the level 2 cache for it, fixing the very slow cfb scrolling problem. As an added bonus this stops us from reserving the framebuffer when simplefb is not used because an older kernel is booted, or hdp is used and no hdmi cable was plugged in, freeing up the memory for kernel use in these cases.

2015-02-02sunxi: video: Force h/vsync active high when using ext. vga dac on some boardsHans de Goede
On both my A13-OLinuxIno and my A13-OLinuxIno-Micro, the vga output gives an unstable image when active low v or hsync is used. The problem seems to be specific to the OLinuxIno A13 (normal & micro) boards. I've just looked up the schematics and they use an opendrain driver for the vga sync lines, and with sync pulses it is the logical high->low edge of the pulse which counts for the timing, which with an active low sync is being driven by the pull-up, and that simply seems to not drive it hard enough to get a stable image. So force v and hsync active high on these boards. independent of what the modeline says. This fixes the unstable image.
