misc: at24: replace memory_accessor with nvmem_device_read

2016-03-02T00:55:48Z

Now that the AT24 uses the NVMEM framework, replace the memory_accessor in the setup() callback with nvmem API calls. Signed-off-by: Andrew Lunn Acked-by: Srinivas Kandagatla Tested-by: Sekhar Nori Acked-by: Wolfram Sang Signed-off-by: Greg Kroah-Hartman

eeprom: 93xx46: extend driver to plug into the NVMEM framework

2016-03-02T00:55:48Z

Add a regmap for accessing the EEPROM, and then use that with the NVMEM framework. Enable backward compatibility in the NVMEM config structure, so that the 'eeprom' file in sys is provided by the framework. Signed-off-by: Andrew Lunn Acked-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

eeprom: at25: Remove in kernel API for accessing the EEPROM

2016-03-02T00:55:48Z

The setup() callback is not used by any in kernel code. Remove it. Any new code which requires access to the eeprom can use the NVMEM API. Signed-off-by: Andrew Lunn Acked-by: Srinivas Kandagatla Acked-by: Wolfram Sang Signed-off-by: Greg Kroah-Hartman

misc: eeprom_93xx46: Add support for a GPIO 'select' line.

2016-02-12T03:23:28Z

This commit adds support to the eeprom_93x46 driver allowing a GPIO line to function as a 'select' or 'enable' signal prior to accessing the EEPROM. Signed-off-by: Cory Tusar Tested-by: Chris Healy Reviewed-by: Vladimir Zapolskiy Signed-off-by: Greg Kroah-Hartman

misc: eeprom_93xx46: Add quirks to support Atmel AT93C46D device.

2016-02-12T03:23:28Z

Atmel devices in this family have some quirks not found in other similar chips - they do not support a sequential read of the entire EEPROM contents, and the control word sent at the start of each operation varies in bit length. This commit adds quirk support to the driver and modifies the read implementation to support non-sequential reads for consistency with other misc/eeprom drivers. Tested on a custom Freescale VF610-based platform, with an AT93C46D device attached via dspi2. The spi-gpio driver was used to allow the necessary non-byte-sized transfers.

misc: eeprom_93xx46: Fix 16-bit read and write accesses.

2016-02-10T01:27:45Z

Compatible at93xx46 devices from both Microchip and Atmel expect a word-based address, regardless of whether the device is strapped for 8- or 16-bit operation. However, the offset parameter passed in when reading or writing at a specific location is always specified in terms of bytes. This commit fixes 16-bit read and write accesses by shifting the offset parameter to account for this difference between a byte offset and a word-based address.
