Subject: [PATCH 0/1] Fallback mechanism for GETMXDS CCC
Date: Mon, 11 Sep 2023 16:24:55 +0800 [thread overview]
Message-ID: <20230911082456.23239-1-joshua.yeong@starfivetech.com> (raw)
Some I3C hardware will report error when incorrect length is received from
device. GETMXDS CCC are availble in 2 formats; without turnaround time (format
1) and with turnaround time (format 2). There is no mechanics to determine which
format is supported by device. In case sending GETMXDS CCC format 2 resulted
failure, try sending GETMXDS CCC format 1 instead.
