If all three channels are disabled via in[123]_enable ABI,
the driver could suspend the chip for power saving purpose.
So this patch adds the PM runtime support in order to gain
more power control than system suspend and resume use case.
For PM runtime, there are a few related changes happening:
1) Added a new pm_dev device pointer for all the PM runtime
callbacks. This is because hwmon core registers a child
device for each hwmon driver and passes it back to each
driver. So there might be a mismatch between two device
pointers in the driver if mixing using them.
2) Added a check in ina3221_is_enabled() to make sure that
the chip is resumed.
3) Bypassed the unchanged status in ina3221_write_enable()
in order to keep the PM runtime refcount being matched.
4) Removed the reset routine in the probe() by calling the
resume() via pm_runtime_get_sync() instead, as they're
similar. It's also necessary to do so to match initial
PM refcount with the number of enabled channels.

The data might need some time to get ready after channel enabling,
although the data register is always readable. The CVRF bit is to
indicate that data conversion is finished, so polling the CVRF bit
before data reading could ensure the result being valid.
An alternative way could be to wait for expected time between the
channel enabling and the data reading. And this could avoid extra
I2C communications. However, INA3221 seemly takes longer time than
what's stated in the datasheet. Test results show that sometimes
it couldn't finish data conversion in time.
So this patch plays safe by adding a CVRF polling to make sure the
data register is updated with the new data.

This change adds a mutex to serialize accesses of sysfs attributes.
This is required when polling CVRF bit of the MASK/ENABLE register
because this bit is cleared on a read of this MASK/ENABLE register
or a write to CONFIG register, which means that this bit might be
accidentally cleared by reading other fields like alert flags.
So this patch adds a mutex lock to protect the write() and read()
callbacks. The read_string() callback won't need the lock since it
just returns the label without touching any hardware register.

There is nothing critically wrong to read these two attributes
without having a is_enabled() check at this point. But reading
the MASK_ENABLE register would clear the CVRF bit according to
the datasheet. So it'd be safer to fence for disabled channels
in order to add pm runtime feature.

The OCC provides a variety of additional information about the state of
the host processor, such as throttling, error conditions, and the number
of OCCs detected in the system. This information is essential to service
processor applications such as fan control and host management.
Therefore, export this data in the form of sysfs attributes attached to
the platform device (to which the hwmon device is also attached).

Add method to parse the response from the OCC poll command. This only
needs to be done during probe(), since the OCC shouldn't change the
number or format of sensors while it's running. The parsed response

number and version of sensors, which we need to instantiate hwmon
attributes.

The OCC is a device embedded on a POWER processor that collects and
aggregates sensor data from the processor and system. The OCC can
provide the raw sensor data as well as perform thermal and power
management on the system.
This driver provides a hwmon interface to the OCC from a service
processor (e.g. a BMC). The driver supports both POWER8 and POWER9 OCCs.
Communications with the POWER8 OCC are established over standard I2C
bus. The driver communicates with the POWER9 OCC through the FSI-based
OCC driver, which handles the lower-level communication details.
This patch lays out the structure of the OCC hwmon driver. There are two
platform drivers, one each for P8 and P9 OCCs. These are probed through
the I2C tree and the FSI-based OCC driver, respectively. The patch also
defines the first common structures and methods between the two OCC
versions.

Recent changes in the mvneta driver reworked allocation
and handling of the ingress buffers to use entire pages.
Apart from that in SW BM scenario the HW must be informed
via PRXDQS about the biggest possible incoming buffer
that can be propagated by RX descriptors.
The BufferSize field was filled according to the MTU-dependent
pkt_size value. Later change to PAGE_SIZE broke RX operation
when usin 64K pages, as the field is simply too small.
This patch conditionally limits the value passed to the BufferSize
of the PRXDQS register, depending on the PAGE_SIZE used.
On the occasion remove now unused frag_size field of the mvneta_port
structure.

Create a net bridge, add eth and vnet to the bridge. The vnet is used
by a virtual machine. When ping the virtual machine from the outside
host and the virtual machine send multicast at the same time, the ping
package will lost.
The multicast package send to the eth, eth will send it to the bridge too,
and the bridge learn the mac of eth. When outside host ping the virtual
mechine, it will match the promisc entry of the eth which is not expected,
and the bridge send it to eth not to vnet, cause ping lost.
So this patch change promisc tcam entry position to the END of 512 tcam
entries, which indicate lower priority. And separate one promisc entry to
two: mc & uc, to avoid package match the wrong tcam entry.
