Subject: [PATCH] wifi: rt2x00: Add support for loading EEPROM from devicetree
|
|
embedded data
|
|
|
|
This patch allows rt2x00 to load eeprom from devicetree embedded data.
|
|
|
|
Example:
|
|
|
|
/* load eeprom from embedded data 'eeprom-data' */
|
|
&wmac {
|
|
ralink,eeprom-data = <0xffffffff 0xffffffff 0xffffffff 0xffffffff 0xffffffff 0xffffffff 0xffffffff 0xffffffff
