[PATCH 0/8] Pin control support for RZ/G2[HN]

[Biju Das]

This patch series adds pin control support for RZ/G2[HN] SoC's.

Also added pinctrl optimization for RZ/G2[HMN] SoC's.

This patches are based on u-boot-sh/next.

+ Geert

The last 3 patches in this series are RFC, which aims to optimize pinctrl
size for RCar SoC 's( The u-boot size is reduced from 1025221 to 964365 bytes)
The saving is around ~60K. Please share your comments.

Note:-
1) I haven't tested the RFC changes on r-car boards due to unavailability of the boards.
2) Optimization is based on the fact that some pins are not enabled in board dts(like DRIF,MSIOF etc..)
