Subject: [PATCH v2 0/5] sunxi: video: Add V3S simple-framebuffer
Date: Fri, 16 Oct 2020 19:17:00 +0200 [thread overview]
Message-ID: <20201016171705.49609-1-m.cerveny@computer.org> (raw)
There are patches to enable "allwinner,simple-framebuffer"
with "mixer0-lcd0" pipeline for V3s.
First patch updates V3s dts(i) from Linux-v5.9.
Second patch enable simple-framebuffer in V3s dtsi
(planed merge in Linux-v5.11)
Third patch enable PWM0 (for backlight support).
Fourth 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. PLL3 does not support doubleclock.
- V3s supports resolution upto 1024x1024. Also scale down memory
requirements for V3s (64MB embedded DDR2)
- V3s does not support HDMI.
Fifth patch enable PWM drivers and corrects CONFIG_VIDEO_LCD_DCLK_PHASE.
Tested with "Lichee Zero" V3s and 800x600 LCD
(not configured DRM DE2/TCON0/panel in linux DTS).
To enable functionality see TESTING patch at
- https://github.com/mcerveny/u-boot/tree/simplefb_v3s_v2
Changes since v1:
- problematic patch for generic DE2 suppress of doubleclock
search was redesigned for V3s only
- changes dts(i) was synced from Linux-v5.9 and additional
patch to enable simple-framebuffer
