[PATCH v4 0/5] Devicetree support for misc/eeprom/eeprom_93xx46.

From: Cory Tusar <hidden>
Date: 2015-12-10 04:01:08
Also in: lkml

This series of patches adds an initial set of devicetree bindings to the
eeprom_93xx46 driver which mirror the configuration options previously
available as a platform device.  These bindings are then extended to
include support for specific Atmel devices in this family and also to
support GPIO-based selection of the device (e.g. for use with an SPI bus
mux).

Additionally, an address aliasing issue with 16-bit read and write
accesses in the eeprom_93xx46 driver discovered during testing is fixed.

Changes since v3:
  - Tested-by: Chris Healy [off-list ref]
    ...on a separate i.MX51 platform with Microchip 93LC46A EEPROM.

Changes since v2:
  - Changed node name to 'eeprom' in DT bindings example.
  - Simplified several bits of return logic.
  - Removed #ifdef CONFIG_OF.
  - Allow compiler to handle promotion to bool return values.
  - Reworked GPIO handling to use gpiod_* functions throughout (and
    fixed an oversight where GPIO flags were being ignored).

Changes since v1:
  - Consolidated all Documentation/devictree additions into a single patch.
  - Clarified compatible string shall be only one of the supported values.
  - Renamed the 'select-gpio' binding to 'select-gpios'.
