[U-Boot] [PATCH v5 0/4] Add support for Pinebook

[Vasily Khoruzhick]

This series adds support for the Pinebook, an allwinner A64 laptop
produced by Pine64. It also adds support for mmc delay calibration,
R_I2C controller, and addresses the issue with activating video
bridge when any of GPIOs is missing.

This series depends on André's "sunxi: A64/H3/H5 DT updates"

v2: - sync sun50i-a64.dtsi with linux instead of adding missing nodes
    - take sun50i-a64-pinebook.dts from linux
    - don't introduce new Kconfig for A64 MMC calibration
    - improve code in video bridge uclass to check for presensce of
      GPIO instead of ingoring EINVAL errors
v3: - enable calibration for H6 as well
    - init ret variable in video_bridge_set_active()
    - fix order of dts files Makefile
    - split anx6345 binding into sun50i-a64-pinebook-u-boot.dts
    - drop speaker_amp node from pinebook dts
    - drop unnecessary options from defconfig
v4: - sync device tree files with linux-next
v5: - drop patch to sync device tree files with linux-next

[U-Boot] [PATCH v5 1/4] mmc: sunxi: add support for automatic delay calibration

[Vasily Khoruzhick]

A64 and H6 support automatic delay calibration and Linux driver uses it
instead of hardcoded delays. Add support for it to u-boot driver.

Fixes eMMC instability on Pinebook

[U-Boot] [PATCH v5 2/4] dm: video: bridge: don't fail to activate bridge if reset or sleep GPIO is missing

[Vasily Khoruzhick]

Both GPIOs are optional, so we shouldn't fail if any is missing.
Without this fix reset is not deasserted if sleep GPIO is missing.

[U-Boot] [PATCH v5 3/4] sun50i: A64: add support for R_I2C controller

[Vasily Khoruzhick]

Allwinner A64 has a I2C controller, which is in the R_ MMIO zone and has
two groups of pinmuxes on PL bank, so it's called R_I2C.

Add support for this I2C controller and the pinmux which doesn't conflict
with RSB.
