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..)
