From e59986de5ff701494e14c722b78b6e6d513e0ab5 Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Fri, 14 Jan 2022 18:50:54 +0100 Subject: can: tcan4x5x: regmap: fix max register value The MRAM of the tcan4x5x has a size of 2K and starts at 0x8000. There are no further registers in the tcan4x5x making 0x87fc the biggest addressable register. This patch fixes the max register value of the regmap config from 0x8ffc to 0x87fc.
