Subject: [PATCH v6 13/17] phy: sun4i-usb: Add support for the H616 USB PHY
Date:   Wed, 19 May 2021 11:41:48 +0100
Message-Id: <20210519104152.21119-14-andre.przywara@arm.com>
In-Reply-To: <20210519104152.21119-1-andre.przywara@arm.com>
References: <20210519104152.21119-1-andre.przywara@arm.com>
Precedence: bulk

The USB PHY used in the Allwinner H616 SoC inherits some traits from its
various predecessors: it has four full PHYs like the H3, needs some
extra bits to be set like the H6, and puts SIDDQ on a different bit like
the A100. Plus it needs this weird PHY2 quirk.

Name all those properties in a new config struct and assign a new
compatible name to it.
