Subject: [PATCH 3/8] leds: syscon: Support 'reg' in addition to 'offset' for register address
Date: Thu, 9 Sep 2021 16:31:13 -0500 [thread overview]
Message-ID: <20210909213118.1087083-4-robh@kernel.org> (raw)
In-Reply-To: <20210909213118.1087083-1-robh@kernel.org>
The register-bit-led binding now also supports 'reg' in addition to
'offset' for the register address. Add support to the driver to get the
address from 'reg'.
