* MLK-10655 Video: Fix second line string display issueYe.Li2015-04-29-4/+5
| | | | | | | | | | The string display on second line repeats the last word of first line and does not show full. This is the bug introduced by the fixing to MLK-10542.

* MLK-10542 video: Support multiple lines version string displayYe.Li2015-04-29-7/+23
| | | | | | | | | | | | The caculation of left space for version string is not correct, should use VIDEO_COLS not VIDEO_LINE_LEN / 2, otherwise we will get larger space than actual have and cause string to overlay logo picture. Also current version string display only supports two lines words at max. This also causes overlay when the LCD pixel colume size is not enough.

* ENGR00325088 video: mxsfb: Disable LCDIF correctlyLiu Ying2015-04-29-5/+9
| | | | | | | | | | | | | | | | | | | | | Let's use the i.MX common miscellaneous reset API to reset the LCDIF block so that we may eliminate a random hang issue at the arch_preboot_os() stage when we disable the LCDIF. This patch also waits for a VSYNC interrupt to guarantee the reset is done at the VSYNC edge, which somehow makes the LCDIF consume the display FIFO(?) and helps the LCDIF work normally at the kernel stage.

* ENGR00315499-22 video: ipu: wait for DP SF end irq when disabling sync BG flowLiu Ying2015-04-29-3/+3
| | | | | | | | | | | | | | | Instead of waiting for DC triple buffer to be cleared, this patch changes to wait for a relevant DP sync flow end irq when disabling sync BG flows. In this way, we align the implement to the FSL internal IPUv3 driver. After applying this patch, the uboot hang up issue at the arch_preboot_os stage on the MX6DL platforms is not observed any more.

* MLK-10774-5 Add EPDC splash screen for MX 6DL SabreSD and 6SL EVKPeng Fan2015-04-29-0/+454
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add EPDC splash screen feature for MX6SL EVK, and MX6DL SABRESD board. - Currently, splash screen consists of a simple black border around a white screen. Done this way to save in memory footprint. - EPDC splash screen is disabled by default in the config file for MX6DL_SABRESD and MX6SL_EVK. If left enabled, the U-Boot image will not boot correctly (hang), since some additional content on the boot device (waveform file) is required for EPDC splash to work correctly.

* drivers/video/am335x-fb: Add possibility to wait for stable power/pictureHannes Petermaier2015-03-05-7/+15
| | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | Testing has shown that on sun4i the display backend engine does not have deep enough fifo-s causing flickering / tearing in full-hd mode due to fifo underruns. On sun4i use the display frontend engine to do the dma from memory, as the frontend does have deep enough fifo-s. As added advantage of this is that it results in much better memory bandwidth as it reduces the amount of dram bank switches, for more details see: http://ssvb.github.io/2014/11/11/revisiting-fullhd-x11-desktop-performance-of-the-allwinner-a10.html Note that this changes the pipeline searched for in the simplefb node, we can get away with doing this now, since no kernel has yet shipped with simplefb dtb nodes, and I will make sure to get a simplefb node with the new pipeline into 3.19 before it ships.

* video: ssd2828: Allow using 'pclk' as the PLL clock sourceSiarhei Siamashka2015-01-22-7/+28
| | | | | | | | | | | | | | | | | | | Instead of using the internal 'tx_clk' clock source, it is also possible to use the pixel clock signal from the parallel LCD interface ('pclk') as the reference clock for PLL. The 'tx_clk' clock speed may be different on different boards/devices (the allowed range is 8MHz - 30MHz). Which is not very convenient, especially considering the need to know the exact 'tx_clk' clock speed. This clock speed may be difficult to identify without having device schematics and/or accurate documentation/sources every time. Using 'pclk' is free from all these problems.

* video: Add support for SSD2828 (parallel LCD to MIPI bridge)Siarhei Siamashka2015-01-22-0/+616
| | | | | | | | | | | | | | | | | | | SSD2828 can take pixel data coming from a parallel LCD interface and translate it on the fly into MIPI DSI interface for driving a MIPI compatible TFT display. SSD2828 is configured over SPI interface, which may or may not have MISO pin wired up on some hardware. So a write-only SPI mode also has to be supported. The SSD2828 support code is implemented as a utility function and needs to be called from real display drivers, which are responsible for driving parallel LCD hardware in front of the video pipeline. The usage instructions are provided as comments in the header file.

* sunxi: display: Make lcd display clk phase configurableHans de Goede2015-01-22-6/+1
| | | | | | | | | | | | | | | | | | | | While running some tests with an Olinuxino-A13-Micro + a 7" Olimex LCD module I noticed that the screen flickered. This is caused by the lcd display clk phase reg value being set to 0, where it should be 1 in this setup. This commit adds a Kconfig option for the lcd display clk phase, so that we can set it per board. This defaults to 1, because looking at all the fex files in sunxi-boards, that is by far the most used value. This commit updated the Ippo and MSI Primo73 tablet defconfigs to override the default of 1 with 0, as that is the correct value for those tablets, this keeps the register settings the same as before this commit. The Olinuxino-A13 defconfigs are not updated, changing the register setting for these boards from 0 to 1, this is intentional.
