Subject: [PATCH v3 0/4] rewrite mtk-quadspi spi-nor driver with spi-mem
Date: Fri,  6 Mar 2020 16:50:48 +0800
Message-ID: <20200306085052.28258-1-gch981213@gmail.com> (raw)

This patchset adds a spi-mem driver for Mediatek SPI-NOR controller,
which already has limited support by mtk-quadspi. This new driver can
make use of full quadspi capability of this controller.

1st new commit makes spi-max-frequency optional to match current
binding doc and make this new driver compatible with old driver dt
bindings.

Change since v2:
 revert binding example replacement and add a dummy irq binding

Changes since v1:
 two new commits.

Chuanhong Guo (4):
  spi: make spi-max-frequency optional
  spi: add support for mediatek spi-nor controller
  dt-bindings: convert mtk-quadspi binding doc for spi-mtk-nor
  mtd: spi-nor: remove mtk-quadspi driver
