Add the full name of the devicetree node to the adapter name.
Without this change, all adapters have the same name making it difficult
to distinguish between multiple instances.
The most obvious way to see this is to use the utility i2c_detect.
e.g. "i2c-detect -l"
Before
i2c-1 i2c Broadcom iProc I2C adapter I2C adapter
i2c-0 i2c Broadcom iProc I2C adapter I2C adapter
After
i2c-1 i2c Broadcom iProc (i2c@e0000) I2C adapter
i2c-0 i2c Broadcom iProc (i2c@b0000) I2C adapter
Now it is easy to figure out which adapter maps to a which DT node.

Enable the i2c-piix4 SMBus controller driver to enumerate I2C slave
devices using ACPI. It builds on the related I2C mux device work
in commit 8eb5c87a92 ("i2c: add ACPI support for I2C mux ports")
In the i2c-piix4 driver the adapters are enumerated as:
Main SMBus adapter Port 0, Port 2, ..., aux port (i.e., ASF adapter)
However, in the AMD BKDG documentation[1], the implied order of ports is:
Main SMBus adapter Port 0, ASF adapter, Port 2, Port 3, ...
This ordering difference is unfortunate. We assume that ACPI
developers will use the AMD documentation ordering, so we have to
pass an extra parameter to piix4_add_adapter().

The i2c-ocores device is an HDL component that get instantiated in FPGA.
The software stack used to drive an FPGA can be very different, and the
i2c-ocore ip-core must work in different context. With respect to this
patch the IRQ controller behind this device, and its driver, can have
different implementations (nested threads). For this reason, it is safer
to use `request_any_context_irq()` to avoid errors at probe time.

i2c_new_device() (where the corresponding parameter is declared as

This device contains both master and slave controllers which can be
enabled simultaneously. Both controllers share the same SDA/SCL lines
and interrupt source but has separate control and status registers.
Controllers also works in loopback mode - slave device can communicate
with its own master controller internally. The controller can handle up
to two addresses, both of which may be 10 bit. Most of the logic
(sending (N)ACK, handling repeated start or switching between
write/read) is handled automatically which makes working with this
controller quite easy.
For simplicity, this patch adds basic support, limiting to only one
slave address. Support for the 2nd device may be added in the future.
Note that synchronize_irq() is used to ensure any running slave interrupt
is finished to make sure slave i2c_client structure can be safely used
by i2c_slave_event.

*** DEADLOCK ***
The problem is that the CHT Whiskey Cove PMIC's builtin i2c-adapter is
itself a part of an i2c-client (the PMIC). This means that transfers done
through it take adapter->bus_lock twice, once for the parent i2c-adapter
and once for its own bus_lock. Lockdep does not like this nested locking.
To make lockdep happy in the case of busses with muxes, the i2c-core's
i2c_adapter_lock_bus function calls:
rt_mutex_lock_nested(&adapter->bus_lock, i2c_adapter_depth(adapter));
But i2c_adapter_depth only works when the direct parent of the adapter is
another adapter, as it is only meant for muxes. In this case there is an
i2c-client and MFD instantiated platform_device in the parent->child chain
between the 2 devices.
This commit overrides the default i2c_lock_operations, passing a hardcoded
depth of 1 to rt_mutex_lock_nested, making lockdep happy.
Note that if there were to be a mux attached to the i2c-wc-cht adapter,
this would break things again since the i2c-mux code expects the
root-adapter to have a locking depth of 0. But the i2c-wc-cht adapter
always has only 1 client directly attached in the form of the charger IC
paired with the CHT Whiskey Cove PMIC.

Here's the first batch of fixes for this release cycle.
Main diffstat here is the re-deletion of netx. I messed up and most
likely didn't remove the files from the index when I test-merged this
and saw conflicts, and from there on out 'git rerere' remembered the
mistake and I missed checking it. Here it's done again as expected.
Besides that:

- i.MX fixlets for i2c/SAI/pinmux
- sleep.S build fix for Davinci
- Broadcom devicetree build/warning fix

Hi Linus,
Please, pull the following patches that mark switch cases where we are
expecting to fall through. These patches are part of the ongoing efforts
to enable -Wimplicit-fallthrough. Most of them have been baking in linux-next
for a whole development cycle.
Also, pull the Makefile patch that globally enables the
-Wimplicit-fallthrough option.
Finally, some missing-break fixes that have been tagged for -stable:
- drm/amdkfd: Fix missing break in switch statement
- drm/amdgpu/gfx10: Fix missing break in switch statement
Notice that with these changes, we completely get rid of all the
fall-through warnings in the kernel.
Thanks
