Subject: dt-bindings: can: tcan4x5x: fix mram-cfg RX FIFO config
From: Marc Kleine-Budde <mkl@xxxxxxxxxxxxxx>
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")
