Actually we always use R1B with CMD6 as per spec.
I fully agree that R1B is preferable, but it's not against the spec to send CMD13 to poll for busy.
Moreover, we need to cope with the scenario when the host has specified a maximum timeout that isn't sufficiently long enough for the requested operation. Do you have another proposal for how to manage this, but disabling MMC_RSP_BUSY?
Let's assume you driver would get a R1B for the CMD6 (we force it), then what timeout would the driver be using if we would set cmd.busy_timeout to 30ms?
/s/30ms/30s
Kind regards Uffe
