Subject: [PATCH v1 0/2] Check for device supported event rings and channels
Date: Fri, 23 Oct 2020 19:00:41 -0700 [thread overview]
Message-ID: <1603504843-38557-1-git-send-email-hemantk@codeaurora.org> (raw)
This change is introduced to make sure device supported hardware event ring,
hardware channels, total number of event rings and total number of channels
match with MHI host controller. In case of a mismatch, driver bails out and
does not move MHI device to M0 from Ready state.
