Subject: [PATCH 06/20] phy: qcom-qmp-pcie-msm8996: clean up ready and status polling
Date: Wed, 12 Oct 2022 10:49:48 +0200 [thread overview]
Message-ID: <20221012085002.24099-6-johan+linaro@kernel.org> (raw)
In-Reply-To: <20221012085002.24099-1-johan+linaro@kernel.org>
Clean up the PHY ready and status polling by dropping the configuration
masks which are no longer needed since the QMP driver split.
