[PATCH 0/5] sunxi: video: Add V3S simple-framebuffer

[Martin Cerveny]

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).
