Subject[PATCH v2 0/3] phy: ti-pipe3: dra7: sata: allow suspend to RAM (core-retention)
Date
Hi,

We fix 2 things here to ensure that PHY clocks are disabled during
system suspend.

1) Stop relying on pm_runtime ops to disable our clocks as they don't
fit in well with the PHY framework usage scenario. This ensures that all clocks are
disabled when phy_exit() is called.

2) Implement workaround for SATA errata i783 (SATA Lockup After SATA DPLL Unlock/Relock)
so that we can now turn off sata_refclk to support suspend-to-ram without preventing
core-retention.

Changelog:
v2:
- Fixed pcie disable_clocks. Addressed review comments.

cheers,
-roger
