[PATCH v3 0/9] Add pinctrl/GPIO and SPI NOR support for Spacemit K1

[Raymond Mao]

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

This series adds pinctrl, GPIO, and SPI NOR flash support for the
SpacemiT K1.  Drivers are usable in both SPL and U-Boot proper.  In
SPL, the QSPI controller and SPI NOR flash are probed during early
init, and the SPL boot device is changed from memory-mapped NOR to
SPI so the common loader reads the next-stage image from NOR.  It
sits on top of the K1 SPL bring-up series [1], which depends on the
K1 clock/reset/dts migration series [2].

To apply on origin/master, two prerequisite series on lore must be
applied first, in this order:

  1. K1 clock/reset/dts migration [2]    (8 patches)
  2. K1 SPL bring-up v4 [1]              (14 patches)
  3. This series                         (9 patches)
