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. Fixes: 6e1caaf8ed22 ("can: tcan4x5x: fix max register value") Link: https://lore.kernel.org/all/20220119064011.2943292-1-mkl@pengutronix.de Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
