Subject: [PATCH v4 0/5] Unify simple reset drivers
Date: Tue, 17 Oct 2017 15:03:01 +0200 [thread overview]
Message-ID: <20171017130306.881-1-p.zabel@pengutronix.de> (raw)
Hi,
This series introduces common reset ops for simple reset controllers.
"Simple" in this context means that they allow to directly control reset
lines by setting and clearing bits in a single register or in a contiguous
register range that is exclusive to the reset controller.
Parts of the sunxi driver and the socfpga, stm32, and zx2967 drivers are
merged into a single reset-simple driver.
The sunxi driver is kept around to register the early reset controllers,
but it reuses the exported reset_simple_ops.
Changes since v3 [1]:
- Split the first patch into reset-simple addition (now patch 1)
and reset-sunxi conversion (now patch 2). I'd really like to get
an ok from the sunxi maintainers for the second one.
- Rename reset_simple_set to reset_simple_update, as that function
is used to both set and clear the control bit.
- Changed reset-simple to only ever warn about the missing
"altr,modrst-offset" property on socfpga, in case another compatible
will use a non-zero default reg_offset in the future.
- Dropped patch 5 ("reset: simple: read back to make sure changes are
applied"). Its use is purely theoretical, and this series is about
unifying the existing drivers.
