This series of patches extends recently accepted devicetree bindings in the
eeprom_93xx46 driver to include support for a specific Atmel device in this
family, and also to support GPIO-based selection of the device (e.g. for use
with an SPI bus mux).
Changes since v5:
- Dropped patches 1-3 which were already accepted.
- Rebased and re-tested atop the 'char-misc-testing' branch of
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
Changes since v4:
- Only forward-declare 'struct gpio_desc' in eeprom_93xx46.h.
- Reviewed-by: Vladimir Zapolskiy <v...@mleia.com>
Changes since v3:
- Tested-by: Chris Healy <chris.he...@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'.
