Subject: [PATCH v4 03/11] dt-bindings: i2c: dw: Add Baikal-T1 SoC I2C controller
Date: Wed, 27 May 2020 15:01:03 +0300 [thread overview]
Message-ID: <20200527120111.5781-4-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20200527120111.5781-1-Sergey.Semin@baikalelectronics.ru>
Add the "baikal,bt1-sys-i2c" compatible string to the DW I2C binding. Even
though the corresponding node is supposed to be a child of the Baikal-T1
System Controller, its reg property is left required for compatibility.

Changelog v2:
- Make the reg property being optional if it's Baikal-T1 System I2C DT
node.
Changelog v3:
- Get back the reg property being mandatory even if it's Baikal-T1 System
I2C DT node. Rob says it has to be in the DT node if there is a
dedicated registers range in the System Controller registers space.
