From: Florian Fainelli 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.
