Date: Wed, 6 Jan 2016 22:54:59 -0500 Message-Id: <1452138904-24820-1-git-send-email-cory.tusar@pid1solutions.com> X-Mailer: git-send-email 2.4.10 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org 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 Changes since v3: - Tested-by: Chris Healy ...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'.
