This patch moves to nvmem support in the driver to use callback instead of regmap. Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Enable this driver to get read/write support to most I2C EEPROMs
|
|
and compatible devices like FRAMs, SRAMs, ROMs etc. After you
|
|
configure the driver to know about each chip on your target
|
|
board. Use these generic chip names, instead of vendor-specific
|
|
ones like at24c64, 24lc02 or fm24c04:
|
|
|
|
24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08,
|
|
24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024
|
|
|
|
Unless you like data loss puzzles, always be sure that any chip
|
|
you configure as a 24c32 (32 kbit) or larger is NOT really a
|
|
24c16 (16 kbit) or smaller, and vice versa. Marking the chip
|
|
as read-only won't help recover from this. Also, if your chip
|
|
has any software write-protect mechanism you may want to review the
|
|
code to make sure this driver won't turn it on by accident.
|
|
|
|
If you use this with an SMBus adapter instead of an I2C adapter,
|
|
full functionality is not available. Only smaller devices are
|
|
supported (24c16 and below, max 4 kByte).
|
|
|
|
This driver can also be built as a module. If so, the module
|
|
will be called at24.

EEPROMs could theoretically be available on other devices as well.

erase the whole EEPROM.
