Subject: [PATCH v6 0/6] Add CPU clock support for Armada 7K/8K
Date: Wed, 19 Jun 2019 16:15:33 +0200 [thread overview]
Message-ID: <20190619141539.16884-1-gregory.clement@bootlin.com> (raw)
Hello,
This is the sixth version of a series allowing to manage the cpu clock
for Armada 7K/8K.
For these SoCs, the CPUs share the same clock by cluster, so actually
the clock management is done at cluster level.
As for the other Armada 7K/8K clocks it is possible to have multiple
AP so here again we need to have unique name: the purpose of the second
patch is to share a common code which will be used in 3 drivers.
The last 2 patch enable the driver at dt and platform level and will
be applied through the mvebu subsystem.
Changelog v5->v6:
- Restraint the reg property for the child node to not overlap the
other node.
- Give a specific compatible to ap_syscon1.
Changelog v4->v5:
- As requested by the device tree maintainer make the reg property
mandatory
- Updated the device tree files accordingly with the new binding
Changelog v3->v4:
- Rebased on v5.1-rc1
- Mention in the binding that a reg property can be used to make the
device tree maintainer happy in the hope that there will be finally
a review on this patch blocking the whole series.
Changelog v2->v3:
- Add back the first patch documenting the binding
Changelog v1->v2:
- Header cleanup
- Use unsigned int instead of it for cluster member of the ap_cpu_clk struct
- Use clk_hw instead of clk
- Use regmap_read_poll_timeout
- Use for_each_of_cpu_node
- Remove unnecessary WARN_ON()
- Remove headers from armada_ap_cp_helper.h
- Few other minor cleanup
