misc: eeprom: at24: support pm_runtime control

2020-01-23T11:52:57+00:00

Although in the most platforms, the power of eeprom are alway on, some platforms disable the eeprom power in order to meet low power request. This patch add the pm_runtime ops to control power to support all platforms. Signed-off-by: Bibby Hsieh [Bartosz: rebased on top of current at24/for-next] Signed-off-by: Bartosz Golaszewski

eeprom: at24: remove the write-protect pin support

2020-01-09T09:51:13+00:00

NVMEM framework is an interface for the at24 EEPROMs as well as for other drivers, instead of passing the wp-gpios over the different drivers each time, it would be better to pass it over the NVMEM subsystem once and for all. Removing the support for the write-protect pin after adding it to the NVMEM subsystem. Signed-off-by: Khouloud Touil Reviewed-by: Linus Walleij Signed-off-by: Bartosz Golaszewski

Pull i2c updates from Wolfram Sang: "I2C has mostly driver updates this time. The few noteworthy changes are: the core has now support for analog and digital filters with at91 being the first user, a core addition to replace the NULL returning i2c_new_probed_device() with an ERR_PTR variant, and the pxa driver has finally being moved to use the generic I2C slave interface.

eeprom: Warn that the driver is deprecated

2019-10-04T15:56:27+00:00

Deprecating the driver in Kconfig is one thing, but we also need to let the users themselves know. Log a warning each time a device is bound to the deprecated eeprom driver.

eeprom: at24: Improve confusing log message

2019-10-04T08:46:39+00:00

Currently when binding to an spd EEPROM, the at24 drivers logs the following message: 256 byte spd EEPROM, read-only, 0 bytes/write The last part is confusing, as by definition you don't write to a read-only EEPROM, plus "0 bytes/write" makes no sense whatsoever. I propose to have a different message for read-only EEPROMs, which does not include this last part.

eeprom: Deprecate the legacy eeprom driver

2019-09-04T07:57:35+00:00

Time has come to get rid of the old eeprom driver. The at24 driver should be used instead. So mark the eeprom driver as deprecated and give users some time to migrate. Then we can remove the legacy eeprom driver completely.
