Subject: [PATCH v3 4/9] mtd: rawnand: brcmnand: Move OF operations out of brcmnand_init_cs()
Date: Fri, 07 Jan 2022 10:46:09 -0800
Content-Type: text/plain; charset="utf-8"
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.
