[PATCHv5 3/5] pinctrl: mvebu: pinctrl driver for 98DX3236 SoC
From: Chris Packham
Date: Thu Jan 26 2017 - 22:26:39 EST
From: Kalyan Kinthada <kalyan.kinthada@xxxxxxxxxxxxxxxxxxx>
This pinctrl driver supports the 98DX3236, 98DX3336 and 98DX4251 SoCs
from Marvell.

Notes:
Changes in v2:
- include sdio support for the 98DX4251
Changes in v3:
- None
Changes in v4:
- Correct some discrepencies between binding and driver.
- Collect acks from Rob and Sebastian
Changes in v5:
- Update bindings to reflect "gpo" pins
- Use mvebu_mmio_mpp_ctrl instead of armada_xp_mpp_ctrl (note this is reliant
on changes queued in linux-pinctrl)
