[PATCH v1 1/2] PCI: imx6: Fix the wrong order of phy_init() and phy_power_on()

From: Richard Zhu <hongxing.zhu@nxp.com>
Date: 2022-08-22 13:28:29
Also in: linux-pci, linux-phy, lkml
Subsystem: pci driver for imx6, pci native host bridge and endpoint drivers, pci subsystem, the rest · Maintainers: Richard Zhu, Lucas Stach, Lorenzo Pieralisi, Krzysztof Wilczyński, Manivannan Sadhasivam, Bjorn Helgaas, Linus Torvalds

Refer to phy_core driver, phy_init() must be called before phy_power_on().
Fix the wrong order of phy_init() and phy_power_on() here.

Fixes: 1aa97b002258 ("phy: freescale: pcie: Initialize the imx8 pcie standalone phy driver")
