Subject: [PATCH 00/14] ARM: suniv: dts: update Allwinner F1C100
Date: Mon,  7 Mar 2022 14:34:07 +0000	[thread overview]
Message-ID: <20220307143421.1106209-1-andre.przywara@arm.com> (raw)

The Allwinner F1C100 SoC didn't see much love since its initial merge in
2018: the originally submitted .dts files were very basic, and didn't
cover such simple peripherals as MMC and SPI.
On top of that the watchdog compatible string was wrong, leading to a
non-functional watchdog and reset functionality.

This series aims to fix that, after the series MMC and SPI work, and
make dtbs_check comes back clean.
This was tested with mounting a filesystem on /dev/mmcblk0 on a
LicheePi Nano, also with accessing the SPI flash through /dev/mtdblock
and mtd_debug. Reboot and watchdog now also work.

Mainline U-Boot recently gained F1C100 support, and those DT updates are
needed there as well to get full MMC and SPI access.

The series is structured as follows:
- Patches 01/14 and 02/14 fix the watchdog, which allows to properly
  reboot the system.
- Patches 03-06 fix some shortcomings of the existing DT files, to make
  them DT binding compliant.
- Patches 07-09 are Jesse's recent MMC patches, with the comments from
  the last version addressed [1].
- Patches 10-12 add SPI support, to enable access to the SPI flash on
  the LicheePi Nano board.
- The final two patches (13/14 and 14/14) add the F1C100 platform to
  the multi_v5_defconfig, since it was not covered by any other
  defconfig before, and an ARMv5 compliant kernel is not commonly
  offered by distributions.

I saw George's series from two years ago to add USB support[2], that
looks good on the first glance, I will comment on that once I did some
testing on that.

Cheers,
Andre
