This subsystem allows communicating with an integrated modem DSP on many Qualcomm SoCs, e.g. MSM8916 or MSM8974. The driver is a fairly simple glue layer between WWAN and RPMSG and is mostly based on the existing mhi_wwan_ctrl.c and rpmsg_char.c. For more information, see commit message in PATCH 2/3. I already posted a RFC for this a while ago: https://lore.kernel.org/linux-arm-msm/YLfL9Q+4860uqS8f@gerhold.net/ and now I'm looking for some feedback for the actual changes. :) Changes in v3: - PATCH 2/3: Clarify commit message - PATCH 3/3: Fix build error for cdc-wdm.c, use extra tx_blocking() op instead v2: https://lore.kernel.org/netdev/20210618075243.42046-1-stephan@gerhold.net/ Changes in v2: Only in PATCH 3/3 - Fix EPOLLOUT being always set even if poll op is defined - Rename poll() op -> tx_poll() since it should be only used for TX v1: https://lore.kernel.org/netdev/20210615133229.213064-1-stephan@gerhold.net/ ==================== Signed-off-by: David S.
