Subject: [PATCH 0/2] rewrite mtk-quadspi spi-nor driver with spi-mem
Date: Sat, 15 Feb 2020 14:58:24 +0800 [thread overview]
Message-ID: <20200215065826.739102-1-gch981213@gmail.com> (raw)
This patchset adds a spi-mem driver for Mediatek SPI-NOR controller,
which already has limited support by mtk-quadspi. For benefits of
this replacement, please check commit message of the 1st patch.
To keep patchset small for easier reviewing, there will be 3 patchsets
including this one.
1. add the new driver, which is this patchset.
2. update existing dts for the new driver:
spi-max-frequency is missing in current mtk-quadspi binding. Old
driver parses child node manually so it doesn't need this, but
new spi-mem driver is probed via spi subsystem which requires the
presence of spi-max-frequency. Since this doesn't break old driver
support, I'll send this separately as a standalone patch.
3. removing the old driver. I'll create this commit after 1 and 2 are
applied to avoid possible rebasing due to any changes in the old
driver.
