| Subject: can: tcan4x5x: regmap: fix max register value |
| |
| From: Marc Kleine-Budde <mkl@pengutronix.de> |
| |
| [ Upstream commit e59986de5ff701494e14c722b78b6e6d513e0ab5 ] |
| |
| 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") |
