Someone must have read the device tree specification incorrectly,
because we were putting timebase-frequency in the wrong place. This
corrects the issue, moving it from

to

There is only one clocksource in RISC-V. The boot cpu initializes
that clocksource. No need to keep a percpu data structure.

Hi,
This is to report what I think is a problem in the pinctrl-icelake
driver. It seems that when trying to control GPIO pins GPP_A* and
GPIO_B*, the driver ends up writing to incorrect PADCFG registers.
I've reached this conclusion by putting debug prints in the driver,
although this can be seen
The remoteproc core performs automatic boot and shutdown of a remote
processor during rproc_add() and rproc_del() for remote processors
supporting 'auto-boot'. The remoteproc devices not using 'auto-boot'
require either a remoteproc client driver or a userspace client to
use the sysfs 'state' varia
The Wakeup M3 remote processor is controlled by the wkup_m3_ipc
client driver, so set the newly introduced 'deny_sysfs_ops' flag
to not allow any overriding of the remoteproc firmware or state

The following series includes couple of fixes and improvements
