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
