treewide: replace with error() with pr_err()

2017-10-04T15:59:44Z

U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory. The semantic patch I used is as follows: // @@@@ -error +pr_err (...) // Signed-off-by: Masahiro Yamada Reviewed-by: Simon Glass [trini: Re-run Coccinelle] Signed-off-by: Tom Rini

dm: video: Add color ANSI escape sequence support

2017-09-29T15:55:16Z

Note that this doesn't differentiate (due to lack of information in video_priv) between different possible component orders for 32bpp. But the main user at this point is efi_loader, and GOP expects xBGR so any video drivers that this is incorrect for already have problems. (Also, conveniently, this matches what simple-framebuffer bindings expect for kernels that use the simple-framebuffer DT binding to take over the bootloader display.) Signed-off-by: Rob Clark

dm: video: Add basic ANSI escape sequence support

2017-09-29T15:53:21Z

Really just the subset that is needed by efi_console. Perhaps more will be added later, for example color support would be useful to implement efi_cout_set_attribute(). Signed-off-by: Rob Clark Reviewed-by: Simon Glass

dm: video: Fix cache flushes

2017-09-29T15:51:29Z

Content can come to screen via putc() and we cannot always rely on updates ending with a puts(). This is the case with efi_console output to vidconsole. Fixes corruption with Shell.efi. Signed-off-by: Rob Clark

video: add config option to skip framebuffer clear

2017-09-12T11:40:47Z

The use-case is that the thing that loaded u-boot already put a splash image on screen. And we want to preserve that until grub boot menu takes over. Signed-off-by: Rob Clark

video: simplefb

2017-09-12T11:40:47Z

Not really qcom specific, but for now qcom/lk is the one firmware that is (afaiu) setting up the appropriate dt node for pre-configured display. Uses the generic simple-framebuffer DT bindings so this should be useful on other platforms. Signed-off-by: Rob Clark

video: add STM32 LTDC display controller

2017-09-12T11:40:47Z

The STM32 LTDC display controller provides a parallel digital RGB and signals for horizontal, vertical synchronization, Pixel Clock and Data Enable as output to interface directly to a variety of LCD and TFT panels. The LTDC main features are: - 24-bit RGB Parallel Pixel Output, Programmable timings & polarity for HSync, VSync and Data Enable. - 2 layers with Blending, Color Keying, Window position & size, Dithering, Background color, Color Look-Up Table (CLUT). - Supported layer color formats: ARGB8888, RGB888, RGB565, ARGB1555, ARGB4444, L8 CLUT, AL44 & AL88 This LTDC driver: - supports: RGB parallel output with timings & polarity, 1 layer in RGB565. - supports but with hard-coded configurations: blending, window position & size (crop), background color. - does not support yet: rgb888, argb8888, 8-bit clut, dithering. This LTDC driver is compatible with all stm32 platforms with the LTDC IP and has been tested on stm32 f746-disco board. Signed-off-by: Philippe CORNU

dm: backlight: Add a driver for GPIO backlight

2017-09-12T11:40:47Z

Add a driver for GPIO backlights. It understands the standard device tree binding. It can be used with simple-panel when PWM is not necessary. Signed-off-by: Patrick Delaunay
