Subject: [RFC, GIT PULL] Late reset controller changes for v5.0
Date: Tue, 08 Jan 2019 18:01:47 +0100	[thread overview]
Message-ID: <1546966907.5406.17.camel@pengutronix.de> (raw)

Dear arm-soc maintainers,

due to a combination of a late merge conflict, early holidays, and the
common cold, I have failed to send the last reset controller pull
request in time for the v5.0-rc1 merge window. As usual there are not
many changes, and they have been carried in linux-next for quite a
while.

One of the changes, commit b3ca9888f35f ("reset: socfpga: add an early
reset driver for SoCFPGA") is necessary for the Stratix10 platform to
boot, since the already merged change 8bb4f3f55961 ("arm64: dts:
stratix10: use "altr,stratix10-rst-mgr" binding") depends on it.

Can you take the whole lot for v5.0-rc2? Should I split out the SoCFPGA
early reset patch + the NULL pointer dereference fix into a separate
"fixes" pull request for v5.0-rc2, postponing the other patches to for-
v5.1? Or do we have to revert 8bb4f3f55961 for now? Please advise.

regards
Philipp

  reset: uniphier-glue: Add AHCI reset control support in glue layer (2019-01-07 16:38:51 +0100)

----------------------------------------------------------------
Late reset controller changes for v5.0

This adds missing deassert functionality to the ARC HSDK reset driver,
fixes some indentation and grammar issues in the kernel docs, adds a
helper to count the number of resets on a device for the non-DT case
as well, adds an early reset driver for SoCFPGA and simple reset driver
support for Stratix10, and generalizes the uniphier USB3 glue layer
reset to also cover AHCI.
