Subject: [PATCH v2 0/4] *** spi cs_timing restructure ***
Date: Tue, 3 Aug 2021 18:22:29 +0800 [thread overview]
Message-ID: <20210803102228.2535-1-Mason.Zhang@mediatek.com> (raw)
Hello,
This patchset has restructure spi cs_timing, as we know spi core has
removed spi_set_cs_timing() API, it is a correct decision because it
asked spi devices to call it in one more time.
so we need find another way to support user set cs_timing. Actually,
spi_device set spi_delay for cs_timing is enough, and about how to
set cs_timing, just put it one the master driver.
We have test this patch in mediatek platform, it can compeletly meets
our needs.
Changed in v2:
- fix tegra spi build err
Mason Zhang (4):
spi: move cs spi_delay to spi_device
spi: modify set_cs_timing parameter
spi: mediatek: modify set_cs_timing callback
spi: tegra114: Fix set_cs_timing param
