There are patches to enable "allwinner,simple-framebuffer" with "mixer0-lcd0" pipeline for V3s.
First patch corrects "2x pll" loop for pixelclock search. Second patch enable PWM0 (for backlight support). Third patch is the main extension to code and build: - V3s has 2x VI and 1x UI channels (use UI channel), so use third channel. - V3s uses PLL3 (PLL_VIDEO) for both DE2 and TCON0 pixelclock. PLL10 is used for DDR2. - V3s supports resolution upto 1024x1024. Also scale down memory requirements for V3s (64MB embedded DDR2) - V3s does not support HDMI. Fourth patch extends u-boot DTS (linux DTS patch coming soon) Fifth patch enable PWM drivers and corrects CONFIG_VIDEO_LCD_DCLK_PHASE. Tested with "Lichee Zero" V3s and 480x272 LCD (not configured DRM DE2/TCON0/panel in linux DTS). - https://github.com/mcerveny/u-boot/tree/simplefb_v3s_v1 Martin Cerveny (5): sunxi: video: No double clock on DE2 pwm: sunxi: v3s: Enable PWM0 sunxi: video: v3s: Enable LCD support arm: dts: v3s: Add support for simple-framebuffer with DE2/TCON sunxi: add drivers and configs needed for LCD display arch/arm/dts/sun8i-v3s.dtsi | 128 +++++++++++++++++- arch/arm/include/asm/arch-sunxi/clock_sun6i.h | 5 +- arch/arm/include/asm/arch-sunxi/gpio.h | 2 + arch/arm/mach-sunxi/Kconfig | 1 + configs/LicheePi_Zero_defconfig | 4 + drivers/pwm/sunxi_pwm.c | 3 + drivers/video/sunxi/lcdc.c | 7 +- drivers/video/sunxi/sunxi_de2.c | 25 +++- drivers/video/sunxi/sunxi_dw_hdmi.c | 2 + drivers/video/sunxi/sunxi_lcd.c | 9 +- 10 files changed, 172 insertions(+), 14 deletions(-) -- 2.17.1
