Subject: [PATCH v4 2/4] pinctrl: mvebu: pinctrl driver for 98DX2530 SoC
This pinctrl driver supports the 98DX25xx and 98DX35xx family of chips
from Marvell. It is based on the Marvell SDK with additions for various
(non-gpio) pin configurations based on the datasheet.
Signed-off-by: Chris Packham <chris.packham@...iedtelesis.co.nz>
Reviewed-by: Andrew Lunn <andrew@...n.ch>

Notes:
Changes in v4:
- None
Changes in v3:
- Use mmio instead of syscon
- Add additional functions based on the datasheet
Changes in v2:
- Make pinctrl a child of a syscon node like the armada-7k-pinctrl
