Subject: [PATCH v2 0/4] rewrite mtk-quadspi spi-nor driver with spi-mem
Date: Fri, 28 Feb 2020 12:36:32 +0800 [thread overview]
Message-ID: <20200228043636.559915-1-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.
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
