Thermal core could not read the temperature after registering the
thermal sensor with thermal_zone_of_sensor_register() because the driver
was not yet initialized.
The call trace looked like:

During probe if the regulator could not be enabled, the error exit path
would still disable it. This could lead to unbalanced counter of
regulator enable/disable.
The patch moves code for getting and enabling the regulator from

The NULL check in probe's error path is not needed because in that time

On some host-only DWC2 ports (like the one in rk3288) when we set
GUSBCFG_FORCEHOSTMODE in GUSBCFG and then read back, we don't see the
bit set. Presumably that's because the port is always forced to HOST
mode so there's no reason to implement these status bits.
Since we know dwc2_core_reset()
From: Yunzhi Li
I found that the probe function of dwc2 driver takes much time
when kernel boot up. There are many long delays in the probe
function these take almost 1 second.
This patch trying to reduce unnecessary delay time.
In dwc2_core_reset() I see it use two at least 20ms delays to
Previously dwc2_get_hwparams() was changing GUSBCFG and not putting it
back the way it was (specifically it set and cleared FORCEHOSTMODE).
Since we want to move dwc2_core_reset() _before_ dwc2_get_hwparams() we
should make sure dwc2_get_hwparams() isn't messing with things in a
permanent way.
In (usb: dwc2: reset dwc2 core before dwc2_get_hwparams()) we added an
extra reset to the probe path for the dwc2 USB controllers. This
allowed proper detection of parameters even if the firmware had already
used the USB part.
Unfortunately, this extra reset is quite slow and is affecting boot
This is a collection of patches, some by Yunzhi Li at Rockchip and some
by me, that fix dwc2_get_hwparams() on some boards (depending on how the
bootloader left things) and then attempt to optimize DWC2's probe
time (since fixing dwc2_get_hwparams() made probe even slower than it
was). Note that

All channel interrupts are bound to specific VCPUs in the guest
at the point channel is created. While currently, we invoke the
polling function on the correct CPU (the CPU to which the channel
is bound to) in some cases we may run the polling function in
a non-interrupt
Util services such as KVP and FCOPY need assistance from daemon's running
in user space. Increase the timeout so we don't prematurely terminate
the transaction in the kernel.

This patch exposes the mapping between Linux CPU number and Hyper-V virtual
processor number. This is necessary because the hypervisor needs to know which
virtual processors to target when making a mapping in the Interrupt Redirection
Table in the I/O MMU.

Before vmbus_connect() synic is setup per vcpu - this means
hypervisor receives writes at synic msr's and probably allocate
hypervisor resources per synic setup.
If vmbus_connect() failed for some reason it's neccessary to cleanup
synic setup by call hv_synic_cleanup() at

This patch exposes the function that hv_vmbus.ko uses to make hypercalls. This
is necessary for retargeting an interrupt when it is given a new affinity.
Since we are exporting this API, rename the API as it will be visible outside
the hv.c file.

When parsing /proc/xxx/maps, the sscanf in perf_event__synthesize_mmap_events
truncate the map name at the space in "/anon_hugepage (deleted)".
is_anon_memory then only receive the string "/anon_hugepage" and do not detect
it.
We change is_anon_memory to only compare the first part of the string

The event log generated by OpenFirmware in PowerPC is 4-byte aligned.
This patch reformats the log to be byte-aligned for the Linux client.

Replace all occurrences of '/ibm,vtpm' with '/vdevice/vtpm',
as only the latter is ganranteed to be available for the client OS.
The '/ibm,vtpm' node should only be used by Open Firmware, which

The OS should ask Power Firmware (PFW) for the size of the buffer
allocated for the event log, instead of the size of the actual
event log. It then passes the buffer adddress and size to PFW in
the handover process, into which PFW copies the log.
