Subject: [PATCH v2 0/3] syscon: Alter syscon and reboot drivers
Date: Fri, 8 May 2020 02:38:43 +0300
Message-ID: <20200507233846.11548-1-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20200306130356.6ABDD8030703@mail.baikalelectronics.ru>

This is a small patchset about tuning the syscon infrastructure a bit.
As it's going to be general in the framework of the Baikal-T1 SoC support
integration into the kernel, we suggest to replace the legacy text-based
syscon-reboot-mode dts-bindings file with yaml-based one. Then seeing a
syscon reboot block is normally expected to be a part of a system
controller and based on the discussion
https://lore.kernel.org/linux-pm/20200306130402.1F4F0803079F@mail.baikalelectronics.ru/
we decided to alter the syscon reboot driver so one would also try to fetch
the syscon registers map from a parental DT node. regmap property is left
supported although it's marked as deprecated from now.

This patchset is rebased and tested on the mainline Linux kernel 5.7-rc4:
0e698dfa2822 ("Linux 5.7-rc4")
tag: v5.7-rc4

Changelog v2:
- Add Sebastian' Acked-by tag to patch 1.
- Use a shorter summary describing the bindings modification patches.
- Our corporate email server doesn't change Message-Id anymore, so the patchset
  is resubmitted being in the cover-letter-threaded format.
- Discard patch with syscon "-endian" property support. As Rob said It shall be
  in the common dt-schema.
- Replace patches of adding a regmap property support to the syscon-reboot-mode
  with patches making syscon-reboot a sub-node of a system controller node.
- Mark regmap property as deprecated from now.
