[PATCH 00/16] Add PIN and SPI support for Spacemit K1

[Raymond Mao]

From: Raymond Mao <raymond.mao at riscstar.com>

Add pinctrl, GPIO, and SPI NOR flash support for the Spacemit K1 SoC
and enable U-Boot to boot on K1-based boards.

Notes:
Tested on the Muse Pi Pro.
BananaPi F3 is untestable due to missing SPI NOR flash.

Prerequisite:
-------------
This series depend on another pending-to-merge series [1].
