Subject: [RESEND PATCH] apalis_t30: fix can2
Date: Tue, 3 Jul 2018 17:03:39 +0200 [thread overview]
Message-ID: <20180703150340.29580-1-marcel@ziswiler.com> (raw)
From: Marcel Ziswiler <marcel.ziswiler@toradex.com>
CAN2 currently fails on probe as follows:
mcp251x spi1.1: Probe failed, err=19
Fix this by enabling input on pin mux of resp. SPI4 pins.
