Subject: [PATCH v3 0/2] phy: freescale: imx8m-pcie: fix and cleanup phy
Date: Mon, 10 Mar 2025 13:27:02 +0100 [thread overview]
Message-ID: <20250310122745.34947-1-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 v3:
- Update commit message of cleanup patch (Frank)
- Add Reviewd-by and Acked-by (Frank and Richard)
Changes in v2:
- Remove unnecessary check if perst is not null (Philipp)
