Subject: [can-next-rfc 13/16] can: tcan4x5x: add max_raw_{read,write} of 256
Date: Wed, 16 Dec 2020 00:17:43 +0100	[thread overview]
Message-ID: <20201215231746.1132907-14-mkl@pengutronix.de> (raw)
In-Reply-To: <20201215231746.1132907-1-mkl@pengutronix.de>

The tcan4x5x chip support bulk read/write, but as the length field is only 8
bits wide, the maximum is 256. A length of 0 is treated as 256.
