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
