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 v4:
- Only forward-declare 'struct gpio_desc' in eeprom_93xx46.h.
- Reviewed-by: Vladimir Zapolskiy <vz@mleia.com>
Changes since v3:
- Tested-by: Chris Healy <chris.healy@zii.aero>
...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'.
