[PATCH 00/10] misc: fastrpc: updates for 7.3

[srini]

From: Srinivas Kandagatla <srini@xxxxxxxxxx>

Hi Greg,

This series collects the FastRPC changes that can be queued for 7.3.

Highlights:

 - Add DSP polling mode support. For dynamic modules running in a user
   PD. Poll mode is opt-in from userspace via the FASTRPC_IOCTL_SET_OPTION
   ioctl (FASTRPC_POLL_MODE) and is only advertised on SoCs whose DSP
   firmware is known to support it.

 - Drop the unhandled DSP PD exit notification in
   fastrpc_rpmsg_callback().

 - A couple of small cleanups: allow fastrpc_buf_free() to accept NULL,
   and move dev_err()/dev_info() calls out of the spinlock in
   fastrpc_cb_probe().

 - MAINTAINERS: drop the inactive Qualcomm maintainer entry and add
   Ekansh Gupta as reviewer.

 - dt-bindings: document qcom,nord-fastrpc and qcom,maili-fastrpc,
   both fall back to qcom,kaanapali-fastrpc. Add cdsp2/cdsp3 labels
   for the four CDSPs on Nord.

These patches are rebased on top of char-misc-next:

Thanks,
