For packets originating from hardware scan, the channel and band is
included in the buffer descriptor (bd->rf_band & bd->rx_ch).
For 2Ghz band the channel value is directly reported in the 4-bit
rx_ch field. For 5Ghz band, the rx_ch field contains a mapping
index (given the 4-bit limitation).
The reserved0 value field is also used to extend 4-bit mapping to
5-bit mapping to support more than 16 5Ghz channels.
This change adds correct reporting of the frequency/band, that is
used in scan mechanism. And is required for 5Ghz hardware scan
support.

With commit db5ad6b7f8 ("nvme-tcp: try to send request in queue_rq
context") r2t and response PDU can get processed while send function
is executing.
Current data digest send code uses req->offset after kernel_sendmsg(),
this creates a race condition where req->offset gets reset before it
is used in send function.
This can happen in two cases -
1. Target sends r2t PDU which resets req->offset.
2. Target send response PDU which completes the req and then req is
used for a new command, nvme_tcp_setup_cmd_pdu() resets req->offset.
Fix this by storing req->offset in a local variable and using
this local variable after kernel_sendmsg().

Since commit ea572f8160 ("PM / devfreq: Change return type of

valid freq_table. The devfreq core unconditionally dereferences
freq_table in the sysfs code and in get_freq_range().
Therefore, we need to ensure that freq_table is both non-null and
non-empty (length is > 0). If either check fails, replace the table
using set_freq_table() or return the error.

When parsing devicetree, the function of_get_devfreq_events(), for each
device child node, iterates over array of possible events "ppmu_events"
till it finds one matching by node name. When match is found the
ppmu_events[i] points to element having both the name of the event and
the counters ID.
Each PPMU device child node might have an "event-name" property with the
name of the event, however due to the design of devfreq it must be the
same as the device node name. If it is not the same, the devfreq client
won't be able to use it via devfreq_event_get_edev_by_phandle().
Since PPMU device child node name must be equal to the "event-name"
property (event-name == ppmu_events[i].name), there is no need to find
the counters ID by the "event-name". Instead use ppmu_events[i].id
which must be equal to it.

use low level P-Unit semaphore lock for axp288 register
accesses directly and for more than one access a time,
to reduce the number of times this semaphore is locked
and released which is an expensive operation.
i2c-bus to the XPower is shared between the kernel and the
SoCs P-Unit. The P-Unit has a semaphore wich the kernel must
lock for axp288 register accesses. When the P-Unit semaphore
is locked CPU and GPU power states cannot change or the system
will freeze.
The P-Unit semaphore lock is already managed inside the regmap
access logic, but for each access the semaphore is locked and
released. So use directly iosf_mbi_(un)block_punit_i2c_access(),
we are safe in doing so because nested calls to the same
semaphore are turned to nops.
