[PATCH v6 0/3] Renesas R9A06G032 PINCTRL Driver

From: Phil Edworthy
Date: Thu Sep 27 2018 - 09:59:34 EST


This implements the pinctrl driver for the RZ/N1 family of devices, including
the R9A06G032 (RZ/N1D) device.

This series was originally written by Michel Pollet whilst at Renesas, and I
have taken over this work.

Main changes:
v6:
- Instead of combining the pin nr and func into a single element, use
a pair of 8-bit elements.
- Simplified how the MDIO function is calculated

v5:
- Address Jacopo's further comments
- Address Geert's comments

v4:
- Address Jacopo's comments
- Add alternative way to use the pinmux prop.
- Remove mention of gpios.
- Implement pin_config_group_get()
- Fix function to get pin configs, i.e. return -EINVAL when disabled.

v3:
- Use standard DT props instead of proprietary ones.
- Replace virtual pins used for MDIO muxing with extra funcs.
- Use pinctrl_utils funcs to handle the maps.
- Remove the dbg functions to keep things simple.
- Change the way the functions are defined so it is easy to check
against the hardware numbering.

v2:
- Change to generic rzn1 family driver, instead of device specific.
- Review comments fixed.
- Fix error handling during probe
