Subject: [PATCH v3 0/3] phy: ti-pipe3: dra7: sata: allow suspend to RAM (core-retention)

Hi,

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.

Depends on http://article.gmane.org/gmane.linux.ports.arm.omap/126670.

Changelog:
v3:
- used scm_conf node in dra7.dtsi for control register access.

v2:
- Fixed pcie disable_clocks. Addressed review comments.

cheers,
-roger
