When phy exists, we use the value of phydev.autoneg to represent the
auto-negotiation state of hardware. Otherwise, we use the value of
mac.autoneg to represent it.

Regualtor suspend/resume functions should only be called by PM suspend
core via registering dev_pm_ops, and regulator devices should implement
the callback functions. Thus, any regulator consumer shouldn't call
the regulator suspend/resume functions directly.
In order to avoid compile errors, two

Some systems need to set regulators to specific states when they enter low
power modes, especially around CPUs.
Currently the regulator driver, for suspend and resume features, provides
two functions which are exported for being called directly by any modules
or subsystems when they thought the re
Some regulator consumers would like to make the regulator device

The items "disabled" and "enabled" are a little redundant, since only one
of them would be set to record if the regulator device should keep on
or be switched to off in suspend states.
So in this patch, the "disabled" was removed, only leave the "enabled":

When an i_op->getattr() call is made on an NFS file
(typically from a 'stat' family system call), NFS
will first flush any dirty data to the server.
This ensures that the mtime reported is correct and stable,
but has a performance penalty. 'stat' is normally thought
to be a quick operation, and

This patch adds support to find next 1 or 0 bit in a xbmitmap range and
clear a range of bits.
More possible optimizations to add in the future:
1) xb_set_bit_range: set a range of bits.
2) when searching a bit, if the bit is not found in the slot, move on to
the next slot directly.
3) add tags to

Two fixups for mediatek's host bridge:
The first patch fixup the IRQ handle routine to avoid IRQ reentry which
may exist for both MT2712 and MT7622.
The second patch fixup class type for MT7622.
Change Since v1:
- Add the second patch.
- Make the first patch's commit messag
From: Honghui Zhang
There maybe a same IRQ reentry scenario after IRQ received in current
IRQ handle flow:
EP device PCIe host driverEP driver
1. issue an IRQ
2. received IRQ
3. clear IRQ status
From: Honghui Zhang
The host bridge of MT7622 has hardware code the class code to an
arbitrary, meaningless value, fix that.
