* clk: renesas: rcar-gen2: Centralize quirks handlingGeert Uytterhoeven2018-04-161-4/+16
| | | | | | | | | | | Introduce centralized quirks handling like on R-Car Gen3, and convert the RZ/G1C SD clock table handling over to it. This makes it easier to add more quirks later, if/when needed.

* clk: renesas: cpg-mssr: Add support to restore core clocks during resumeGeert Uytterhoeven2017-10-201-4/+3
| | | | | | | | | | | | | On R-Car Gen3 systems, PSCI system suspend powers down the SoC, possibly losing clock configuration. Hence add a notifier chain that can be used by core clocks to save/restore clock state during system suspend/resume. The implementation of the actual clock state save/restore operations is clock-specific, and to be registered with the notifier chain in the SoC or family-specific cpg_mssr_info.cpg_clk_register() callback.

* clk: renesas: cpg-mssr: Add common R-Car Gen2 supportSergei Shtylyov2016-11-101-0/+371
Add the common R-Car Gen2 (and RZ/G) Clock Pulse Generator / Module Standby and Software Reset support code, using the CPG/MSSR driver core. Based on the proof-of-concept R8A7791 CPG/MSSR patch by Geert Uytterhoeven <geert+renesas@glider.be>.
