+From: Florian Fainelli <f.fainelli@gmail.com>
+Subject: [PATCH v3 7/9] mtd: rawnand: brcmnand: Allow platform data instantation
+Date: Fri, 07 Jan 2022 10:46:12 -0800
+Content-Type: text/plain; charset="utf-8"
+
+Make use of the recently refactored code in brcmnand_init_cs() and
+derive the chip-select from the platform data that is supplied. Update
+the various code paths to avoid relying on possibly non-existent
+resources, too.
