Subject: [PATCH v2 2/5] phy: qcom-qmp: Increase PHY ready timeout
Date: Fri,  1 Nov 2019 17:16:25 -0700	[thread overview]
Message-ID: <20191102001628.4090861-3-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20191102001628.4090861-1-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.
