Subject: [PATCH v3 4/9] mtd: rawnand: brcmnand: Move OF operations out of brcmnand_init_cs()

|
|
In order to initialize a given chip select object for use by the
|
|
brcmnand driver, move all of the Device Tree specific routines outside
|
|
of brcmnand_init_cs() in order to make it usable in a platform data
|
|
configuration which will be necessary for supporting BCMA chips.
|
|
|
|
No functional changes introduced.
