Add extra cycle for hotplug work queue to handle the case when a signal is
It adds missed logic for signal acknowledge, by adding an extra run for
received, but no specific signal assertion is detected. Such case
theoretically can happen for example in case several units are removed or
inserted at the same time. In this situation acknowledge for some signal
can be missed at signal top aggreagation status level. The extra run will
allow to handler to acknowledge the missed signal.
The interrupt handling flow performs the next steps:
(1)
Enter mlxreg_hotplug_work_handler due to signal assertion.
Aggregation status register is changed for example from 0xff to 0xfd
(event signal group related to bit 1).
(2)
Mask aggregation interrupts, read aggregation status register and save it
(0xfd) in aggr_cache, then traverse down to handle signal from groups
related to the changed bit.
(3)
Read and mask group related signal.
Acknowledge and unmask group related signal (acknowledge should clear
aggregation status register from 0xfd back to 0xff).
(4)
Re-schedule work queue for the immediate execution.
(5)
Enter mlxreg_hotplug_work_handler due to re-scheduling.
Aggregation status is changed from previous 0xfd to 0xff.
Go over steps (2) - (5) and in case no new signal assertion
is detected - unmask aggregation interrupts.
The possible race could happen in case new signal from the same group is
asserted after step (3) and prior step (5). In such case aggregation
status will change back from 0xff to 0xfd and the value read from the
aggregation status register will be the same as a value saved in
aggr_cache. As a result the handler will not traverse down and signal
will stay unhandled.
Example of faulty flow:
The signal routing flow is as following (f.e. for of FANi removing):
- FAN status and event registers related bit is changed;
-- intermediate aggregation status register is changed;
--- top aggregation status register is changed;
---- interrupt routed to CPU and interrupt handler is invoked.
When interrupt handler is invoked it follows the next simple logic (f.e
FAN3 is removed):
(a1) mask top aggregation interrupt mask register;
(a2) read top aggregation interrupt status register and test to which
underling group belongs a signal (FANs in this case and is changed
from 0xff to 0xfb and 0xfb is saved as a last status value);
(b1) mask FANs interrupt mask register;
(b2) read FANs status register and test which FAN has been changed
FAN3 in this example);
(c1) perform relevant action;
<--------------- (FAN2 is removed at this point)
(b3) clear FANs interrupt event register to acknowledge FAN3 signal;
(b4) unmask FANs interrupt mask register
(a3) unmask top aggregation interrupt mask register;
An interrupt handler is invoked, since FAN2 interrupt is not acknowledge.
It should set top aggregation interrupt status register bit 6 (0xfb).
In step (a2)
(a2) read top aggregation interrupt and comparing it with saved value
does not show change (same 0xfb) and after (a2) execution jumps to
(a3) and signal leaved unhandled
The fix will enforce handler to traverse down in case the signal is
received, but signal assertion is not detected.

Instead, use the status FLAG_* defines for the sparse keymap index.
Rather than check for each known bit, use a bitmask to filter for all

This patch adds generic device information to the DMI table of
the cros_ec_lpc driver, needed for Chromebooks/boxes using a
custom coreboot firmware.
The DMI info would not contain "Google_*" as BIOS version string,
instead the system vendor string would still be "GOOGLE", so this
seems to be a reasonable match for every Chromebook/box running
a custom firmware.

Chrome platform installed a Chrome EC notify handler which prevents
default EC GPE handler getting called. Add pm_system_wakeup to the
Chrome EC notify handler so wake up from s2idle can happen.

Mark board data as __intconst/__initdata and make a copy of appropriate
entry once we identified the board we are running on. The rest of the data
will be discarded once the kernel finished booting (or module finished
loading).

Instead of passing interrupt flags via platform data to drivers, or
hoping that drivers will do the right thing and set it up the way we
need, let's set up IRQ resource and attach it to the I2C board info, and
let I2C core set it up for us.

Instead of using platform device and deferrals to handle the case when i2C
adapters appear late in the game, and not handling device unbinding all
that well, let's switch to using I2C bus notifier to get told when a new
I2C adapter appears in the system, and attempt to add appropriate devices
at that time.
In case when we have 2 Designware adapters in the system (Acer C720),
instead of counting and hoping they get enumerate din the right order,
let's switch to using their PCI devids (slot/function) that should be
stable.

Instead of trying to parse DMI IRQ data every time we try to instantiate a
device, let's do it once, when we identify the device we are working with.
This allows us to mark chromeos_laptop_get_irq_from_dmi() as __init and
discard it once module is initialized.

Here is the big set of USB and PHY driver patches for 4.17-rc1.
Lots of USB typeC work happened this round, with code moving from the
staging directory into the "real" part of the kernel, as well as new
infrastructure being added to be able to handle the different types of
"roles" that typeC requires.
There is also the normal huge set of USB gadget controller and driver
updates, along with XHCI changes, and a raft of other tiny fixes all
over the USB tree. And the PHY driver updates are merged in here as
well as they interacted with the USB drivers in some places.
All of these have been in linux-next for a while with no reported
issues.

The Thinkpad P50 has 2 fans. Add the 2FAN quirk so the tpacpi driver
properly reports both fan speeds.
Because the P50 doesn't report the version of its EC controller,
we need to identify it by BIOS version (N1).

We're freeing "value_name" which is NULL, so that's a no-op, but we
intended to free "location_name" instead. And then we don't free the
names in token_location_attrs[0] and token_value_attrs[0].
