Subject: [net-next PATCH 12/13] drivers: net: dsa: qca8k: add support for pws config reg
Date: Thu, 7 Oct 2021 00:36:02 +0200 [thread overview]
Message-ID: <20211006223603.18858-13-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20211006223603.18858-1-ansuelsmth@gmail.com>
Some qca8327 switch require the power_on_sel enabled for the pws_reg or
sets the led to open drain.
Also qca8327 switch have a special mode to declare reduced 48pin layout.
This special mode is only present in qca8327 as qca8337 have a different
pws_reg table.
Introduce a new binding and support these special configuration.
