Subject: [PATCH v2 0/2] phy: freescale: imx8m-pcie: fix and cleanup phy
Date: Wed, 5 Mar 2025 15:43:14 +0100 [thread overview]
Message-ID: <20250305144355.20364-1-eichest@gmail.com> (raw)
The imx8m-pcie PHY PLL fails to lock under certain conditions when
returning from suspend. This is resolved by asserting the PHY reset when
powering off the PHY during suspend. This ensures that the PHY is
properly reset when powering on again in resume.
Changes in v2:
- Remove unnecessary check if perst is not null (Philipp)
Stefan Eichenberger (2):
phy: freescale: imx8m-pcie: cleanup reset logic
phy: freescale: imx8m-pcie: assert phy reset and perst in power off
