soc: fsl: qbman: Fix return value on success

[ Upstream commit 750cf40c0f7088f36a8a5d102e0488b1ac47faf5 ]

On error the function was meant to return -ERRNO.  This also fixes
compile warning:

[ Upstream commit ba34f977c333f96c8acd37ec30e232220399f5a5 ]

APR client incorrectly prints out "ret" variable on pdr_add_lookup failure,
it should be printing the error value returned by the lookup instead.

soc: qcom: pdr: Fixup array type of get_domain_list_resp message

2020-10-29T09:08:13+00:00

[ Upstream commit 7a366707bb6a93baeb1a9ef46c4b9c875e0132d6 ]

The array type of get_domain_list_resp is incorrectly marked as NO_ARRAY.
Due to which the following error was observed when using pdr helpers with
the downstream proprietary pd-mapper. Fix this up by marking it as
VAR_LEN_ARRAY instead.

soc: qcom: rpmh-rsc: Set suppress_bind_attrs flag

2020-08-19T06:26:14+00:00

[ Upstream commit 1a53ce9ab4faeb841b33d62d23283dc76c0e7c5a ]

rpmh-rsc driver is fairly core to system and should not be removable
once its probed. However it allows to unbind driver from sysfs using
below command which results into a crash on sc7180.

echo 18200000.rsc > /sys/bus/platform/drivers/rpmh/unbind

Lets prevent unbind at runtime by setting suppress_bind_attrs flag.

[ Upstream commit 72fe996f9643043c8f84e32c0610975b01aa555b ]

The Protection Domains (PD) have a mechanism to keep its resources
enabled until the PD down indication is acked. Reorder the PD state
indication ack so that clients get to release the relevant resources
before the PD goes down.

soc: qcom: rpmh-rsc: Don't use ktime for timeout in write_tcs_reg_sync()

2020-08-19T06:26:06+00:00

[ Upstream commit be24c6a71ecfbd9436ea1f496eb518a53e06368c ]

The write_tcs_reg_sync() may be called after timekeeping is suspended
so it's not OK to use ktime.  The readl_poll_timeout_atomic() macro
implicitly uses ktime.  This was causing a warning at suspend time.

Change to just loop 1000000 times with a delay of 1 us between loops.
This may give a timeout of more than 1 second but never less and is
safe even if timekeeping is suspended.

NOTE: I don't have any actual evidence that we need to loop here.
It's possibly that all we really need to do is just read the value
back to ensure that the pipes are cleaned and the looping/comparing is
totally not needed.  I never saw the loop being needed in my tests.
However, the loop shouldn't hurt.
