Subject: [PATCH 7/8] i2c: qup: advertise SMBus transfers using RECV_LEN
Date: Sat,  9 Jan 2021 13:43:11 +0100	[thread overview]
Message-ID: <20210109124314.27466-8-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20210109124314.27466-1-wsa+renesas@sang-engineering.com>

This driver implements I2C_M_RECV_LEN, so it can advertise the SMBus
transfers needing it. This also enables client devices to check for the
RECV_LEN capability.
