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.
