Hello there,
This series improves the support for the canaan k210 SoC.
Patch 1 renames a few compatible strings so that the k210 compatible strings are identical to the ones used in Linux.
Patch 2 add missing power bus clocks, which is needed if supplying the u-boot device tree to Linux.
Patch 3 changes two device tree properties into one, in order to be identical to the property used in Linux.
Patch 4 changes the PLIC device tree node so that we actually configure the PLIC the way that we think we do, when booting Linux with the u-boot device tree. (The ordering matters.)
Patch 5 is a workaround for a k210 specific HW bug in the DW SPI.
Patch 6 is a generic bug fix for the DW SPI driver which avoids an IRQ storm which otherwise causes the k210 to hang when booting Linux.
Patch 7-8 are bug fixes for the pinctrl driver used on k210.
Changes since v1: -Incorporated Sean's review comments from V1. -Picked up Sean's Reviewed-by tags. -Added a new patch, patch 4.
Kind regards, Niklas
