From 517ca93a7159eb94eeef829f6ca036456050115c Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Thu, 3 May 2018 22:40:54 +0300 Subject: PCI: rcar: Add R-Car gen3 PHY support On R-Car gen3 SoCs the PCIe PHY has its own register region, thus we need to add the corresponding code in rcar_pcie_hw_init_gen3() and call devm_phy_optional_get() at the driver's probing time, so that the existing R-Car gen3 device trees (not having a PHY node) would still work (we only need to power up the PHY on R-Car V3H).
