  remoteproc: st: Use of_property_present() for testing DT property presence (2023-04-18 18:56:51 -0700)

----------------------------------------------------------------
remoteproc updates for v6.4

Unnecessary type casts from the void * rproc->priv pointer is dropped
throughout te subsystem.

A kernel-doc error is corrected in the Mediatek SCPI IPI implementation.

The firmware loading onto the IMX DSP remote processors is reworked to
avoid non-32bit memory operations. A module parameter is introduced to
assist development of firmware without communication abilities in place.
Error paths in imx_dsp_rproc_mbox_alloc() is cleaned up.

The cluster configuration handling in the TI K3 R5 driver is corrected
and support for the single-R5 core found in the TI AM62x SoC family is
introduced.

The TI PRU driver device- to virtual-address translation is updated to
avoid compiler warning about the unsigned device-address always being
larger than 0.

The ST remoteproc driver is transitioned to use of_property_present().

Issues with kicks arriving after the STM32 remote processor has been
shut down are mitigated by checking the processor's state before
handling them.

Support for mailbox channels for communication with the remote
processors are added to the Xilinx R5 remoteproc driver. The naming of
carveouts are corrected and their parsing is reworked.
For this a couple of fixes targeting the mailbox subsystem are picked up
here as well.

Reference counting of of_nodes are corrected in the ST, STM32, RCAR and
IMX remoteproc drivers.
