> separate series and discussion. Also I dropped the MMC binding patch
> (v1 07/14), since Ulf already applied that.
> Other than that this tries to clarify the watchdog clock situation in a
> new patch (02/12), and fixes some smaller issues, as pointed out by
> Samuel (many thanks for that!).

> 
> 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 01/12 and 03/12 fix the watchdog, which allows to properly
>   reboot the system.
> - Patches 04-07 fix some shortcomings of the existing DT files, to make
>   them DT binding compliant.
> - Patches 08-09 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.

Applied to sunxi/dt-for-5.19, thanks!
