Merge tag 'rproc-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

Pull remoteproc updates from Bjorn Andersson:

- Fix resource cleanup in the remoteproc attach error handling code
paths

- Refactor the various TI K3 drivers to extract and reuse common code
between them

- Add support in the i.MX remoteproc driver for determining from the
firmware if Linux should wait on a "firmware ready" signal at startup

- Improve the Xilinx R5F power down mechanism to handle use cases where
this is shared with other entities in the system
