Subject: [PATCH v2 09/11] phy: qcom-qmp-usb: clean up power-down handling
Date: Thu, 29 Sep 2022 11:29:14 +0200 [thread overview]
Message-ID: <20220929092916.23068-10-johan+linaro@kernel.org> (raw)
In-Reply-To: <20220929092916.23068-1-johan+linaro@kernel.org>
Always define the POWER_DOWN_CONTROL register instead of falling back to
the v2 (and v3) offset during power on and power off.
Signed-off-by: Johan Hovold <johan+linaro@kernel.org>
