Subject: [PATCH v3 0/4] rewrite mtk-quadspi spi-nor driver with spi-mem
Date: Fri, 6 Mar 2020 16:50:48 +0800 [thread overview]
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
