Subject: [PATCH 5.15 164/171] dt-bindings: can: tcan4x5x: fix mram-cfg RX FIFO config

From: Marc Kleine-Budde <mkl@...gutronix.de>

commit 17a30422621c0e04cb6060d20d7edcefd7463347 upstream.

This tcan4x5x only comes with 2K of MRAM, a RX FIFO with a dept of 32
doesn't fit into the MRAM. Use a depth of 16 instead.

Fixes: 4edd396a1911 ("dt-bindings: can: tcan4x5x: Add DT bindings for TCAN4x5X driver")
