[PATCH v2 0/2] spi: enable the SpacemiT K3 SoC QSPI

[Zhengyu He]

Add the SpacemiT K3 QSPI compatible and enable SPI NOR flash on the
K3 Pico-ITX board.

K3 and K1 use the same QSPI controller, so the K3 devicetree uses
"spacemit,k1-qspi" as fallback.

With this, patch 2/3 in v1 is dropped.

This series is based on the for-next branch of:
  https://github.com/spacemit-com/linux

This series is available here:
  https://github.com/imguoguo/linux/tree/k3-pico-itx-qspi-v2

Version 2 addresses review comments on v1:
  - Use "spacemit,k1-qspi" as fallback for the K3 QSPI compatible.
  - Drop v1 patch 2, "spi: fsl-qspi: add SpacemiT K3 support".
  - Reordered Signed-off-by trailers.

Here is version 1:
