Merge tag 'rproc-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc
Pull remoteproc updates from Bjorn Andersson: "This adds support for controlling the PRU and R5F clusters on the TI AM64x, the remote processor in i.MX7ULP, i.MX8MN/P and i.MX8ULP NXP and the audio, compute and modem remoteprocs in the Qualcomm SC8180x platform. It fixes improper ordering of cdev and device creation of the remoteproc control interface and it fixes resource leaks in the error handling path of rproc_add() and the Qualcomm modem and wifi remoteproc drivers. Lastly it fixes a few build warnings and replace the dummy parameter passed in the mailbox api of the stm32 driver to something not living on the stack" * tag 'rproc-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc: (32 commits) remoteproc: qcom: pas: Add SC8180X adsp, cdsp and mpss dt-bindings: remoteproc: qcom: pas: Add SC8180X adsp, cdsp and mpss remoteproc: imx_rproc: support i.MX8ULP dt-bindings: remoteproc: imx_rproc: support i.MX8ULP remoteproc: stm32: fix mbox_send_message call remoteproc: core: Cleanup device in case of failure remoteproc: core: Fix cdev remove and rproc del remoteproc: core: Move validate before device add remoteproc: core: Move cdev add before device add remoteproc: pru: Add support for various PRU cores on K3 AM64x SoCs dt-bindings: remoteproc: pru: Update bindings for K3 AM64x SoCs remoteproc: qcom_wcnss: Use devm_qcom_smem_state_get() remoteproc: qcom_q6v5: Use devm_qcom_smem_state_get() to fix missing put() soc: qcom: smem_state: Add devm_qcom_smem_state_get() dt-bindings: remoteproc: qcom: pas: Fix indentation warnings remoteproc: imx-rproc: Fix IMX_REMOTEPROC configuration remoteproc: imx_rproc: support i.MX8MN/P remoteproc: imx_rproc: support i.MX7ULP remoteproc: imx_rproc: make clk optional remoteproc: imx_rproc: initial support for mutilple start/stop method ...

-to describe these.
