Merge tag 'rproc-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

Pull remoteproc updates from Bjorn Andersson:
"This fixes a race condition in the user space interface for starting
and stopping remote processors, it makes the ELF loader properly skip
zero memsz segments and it cleans up the debugfs tracefile code a bit
by not checking for errors.

It introduces support for controlling the audio DSP on Qualcomm
MSM8226, as well as audio and compute DSPs on Qualcomm SC8280XP.

It makes it possible to specify the firmware path for Mediatek's
remote processors, fixes a double free in the SCP driver and addresses
an issue with the SRAM initialization on MT8195.

Lastly it deprecates the custom ELF loader in the iMX remoteproc
driver, in favor of using the shared one"

remoteproc: core: Move state checking to remoteproc_core

There is no mutex protection of these state checking for 'stop'
and 'detach' which can't guarantee there is no another instance
is trying to do same operation.

Consider two instances case:
Instance1: echo stop > /sys/class/remoteproc/remoteproc0/state
Instance2: echo stop > /sys/class/remoteproc/remoteproc0/state

The issue is that the instance2 case may success, Or it
may fail with -EINVAL, which is uncertain.

So move this state checking in rproc_cdev_write() and
state_store() for 'stop', 'detach' operation to
'rproc_shutdown' , 'rproc_detach' function under the mutex
protection.

remoteproc: core: Remove state checking before calling rproc_boot()

There is no mutex protection of the state checking before rproc_boot(),
which can't guarantee there is no another instance is trying to do
same operation.

Consider two instances case:
Instance1: echo start > /sys/class/remoteproc/remoteproc0/state
Instance2: echo start > /sys/class/remoteproc/remoteproc0/state
...
Instance2: echo stop > /sys/class/remoteproc/remoteproc0/state
...
Instance1: echo stop > /sys/class/remoteproc/remoteproc0/state

The one issue is that the instance2 case may success when 'start'
happens at same time as instance1, then rproc->power = 2; Or it
may fail with -BUSY, then rproc->power = 1; which is uncertain.

The another issue is for 'stop' operation, if the rproc->power = 1,
when instance2 'stop' the remoteproc the instance1 will be
impacted for it still needs the service at that time.

The reference counter rproc->power is used to manage state
changing and there is mutex protection in each operation
function for multi instance case.

So remove this state checking in rproc_cdev_write() and
state_store() for 'start' operation, just let reference
counter rproc->power to manage the behaviors.
