From b8311f46c6f5a2030f43c764e742015867293493 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Fri, 26 May 2023 09:34:42 +0200 Subject: net: dsa: microchip: add an enum for regmap widths It is not immediately obvious that this driver allocates, via the KSZ_REGMAP_TABLE() macro, 3 regmaps for register access: dev->regmap[0] for 8-bit access, dev->regmap[1] for 16-bit and dev->regmap[2] for 32-bit access. In future changes that add support for reg_fields, each field will have to specify through which of the 3 regmaps it's going to go. Add an enum now, to denote one of the 3 register access widths, and make the code go through some wrapper functions for easier review and further modification.
