From 02d1d0e4dfc3fdc5aa05b78e7def00dc1e62257e Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 7 Jan 2022 10:46:11 -0800 Subject: mtd: rawnand: brcmnand: Add platform data structure for BCMA Update the BCMA's chipcommon nand flash driver to detect which chip-select is used and pass that information via platform data to the brcmnand driver. Make sure that the brcmnand platform data structure is always at the beginning of the platform data of the "nflash" device created by BCMA to allow brcmnand to safely de-reference it.
