Subject: [PATCH v2 1/5] phy: qcom-qmp: Increase PHY ready timeout
Date: Fri, 20 Dec 2019 15:47:15 +0530 [thread overview]
Message-ID: <20191220101719.3024693-2-vkoul@kernel.org> (raw)
In-Reply-To: <20191220101719.3024693-1-vkoul@kernel.org>
From: Bjorn Andersson <bjorn.andersson@linaro.org>
It's typical for the QHP PHY to take slightly above 1ms to initialize,
so increase the timeout of the PHY ready check to 10ms - as already done
in the downstream PCIe driver.
