X-Git-Tag: accepted/tizen/unified/20230118.172025~7822^2~27
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=416365e02a33ce50660862a126dd407b09736c7c;p=platform%2Fkernel%2Flinux-rpi.git

i2c: qup: advertise SMBus transfers using RECV_LEN

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.
