misc/at25, dt: support probing at25 SPI EEPROM from DT

2013-10-16T19:36:09+00:00

The commit d6ae0d578d24303941c1424b049d2cae28277666 introduced devicetree
binding documentation for this driver, but the driver itself does not yet
support the documented compatible entry. Fix this by adding the documented
entry to the driver.

misc: at25: use spi_get_drvdata() and spi_set_drvdata()

2013-04-05T22:38:30+00:00

Use the wrapper functions for getting and setting the driver data using
spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we
can directly pass a struct spi_device.

misc: remove use of __devexit

CONFIG_HOTPLUG is going away as an option so __devexit is no
longer needed.

misc/at25, dt: Improve at25 SPI eeprom device tree bindings.

2012-09-05T21:10:29+00:00

Commit 002176db (misc: at25: Parse dt settings) added device tree
bindings the differ significantly in style from the I2C EEPROM
bindings and don't seem well vetted.  Here I deprecate (but still
support) the "at25,*" properties, and add what I hope is a better
alternative.  These new bindings also happen to be deployed in the
field and were previously submitted for consideration here:

https://lists.ozlabs.org/pipermail/devicetree-discuss/2012-May/015556.html

The advantages of the new bindings are that they are similar to the
I2C EEPROMs and they don't conflate read-only and the address width
modes in a binary encoded blob.

Support M95040 SPI EEPROM

2012-04-18T21:57:57+00:00

Updated the generic SPI EEPROM driver AT25 for support of an additional address
bit in the instruction byte. Certain EEPROMS have a size that is larger than the
number of address bytes would allow (e.g. like M95040 from ST that has 512 Byte
size but uses only one address byte (A0 to A7) for addressing.) For the extra
address bit (A8, A16 or A24) bit 3 of the instruction byte is used. This
instruction bit is normally defined as don't care for other AT25 like chips.

MISC: convert drivers/misc/* to use module_spi_driver()

2012-01-25T00:31:49+00:00

This patch converts the drivers in drivers/misc/* to use the
module_spi_driver() macro which makes the code smaller and a bit
simpler.
