Subject: [PATCH 1/2] PCI: tegra: Remove support for ZRX-DC compliant PHY from platform driver
Date: Mon, 28 Oct 2019 18:12:19 +0530 [thread overview]
Message-ID: <1572266540-17626-2-git-send-email-anvesh.s@samsung.com> (raw)
In-Reply-To: <1572266540-17626-1-git-send-email-anvesh.s@samsung.com>
As part of dw_pcie_setup(), PHYs which are compliant to ZRX-DC
specification are already handled based on "snps,phy-zrxdc-compliant"
property in controller DT node. So, instead of handling ZRX-DC
compliant settings in each platform driver, remove this driver
specific code.
