Fixes gcc '-Wunused-but-set-variable' warning: drivers/misc/eeprom/at25.c: In function 'at25_remove': drivers/misc/eeprom/at25.c:384:20: warning: variable 'at25' set but not used [-Wunused-but-set-variable] Since commit 96d08fb43e30 ("eeprom: at25: use devm_nvmem_register()"), at25_remove is do nothing, so can be removed.

eeprom: at25: Add DT support for EEPROMs with odd address bits

2017-12-18T14:59:17Z

Certain EEPROMS have a size that is larger than the number of address bytes would allow, and store the MSB of the address in bit 3 of the instruction byte. This can be described in platform data using EE_INSTR_BIT3_IS_ADDR, or in DT using the obsolete legacy "at25,addr-mode" property. But currently there exists no non-deprecated way to describe this in DT. Hence extend the existing "address-width" DT property to allow specifying 9 address bits, and enable support for that in the driver. This has been tested with a Microchip 25LC040A.

at25: fix debug and error messaging

2016-09-27T10:43:35Z

The patch does the following: - fixes specifiers and removes explicit casting of the parameters - joins literals to one line - increases readability of the parameters Signed-off-by: Andy Shevchenko Signed-off-by: Greg Kroah-Hartman

eeprom: at25: Fix SPI device leak

2016-05-01T21:04:19Z

The at25 driver is using spi_dev_get() apparently just to take a copy of the SPI device used to instantiate it but never calls spi_dev_put() to free it. Since the device is guaranteed to exist between probe() and remove() there should be no need for the driver to take an extra reference to it so fix the leak by just using a straight assignment.

eeprom: at25: remove nvmem regmap dependency

2016-05-01T21:01:00Z

This patch moves to nvmem support in the driver to use callback instead of regmap. Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

eeprom: at25: 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 backwards compatibility in the NVMEM config, 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
