Static structure tsl2550_info, of type i2c_board_info, is referenced
only twice: the first time in arguments to dev_info() (which does not
modify it) and the second time as the last argument to function
i2c_new_device() (where the corresponding parameter is declared as
const). As tsl2550_info is therefore never modified, make it const to
protect it from unintended modifications.
Issue found with Coccinelle.

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.

Since the 2019 a1k.org community re-print of these PCBs sports an
LTC2990 hwmon chip as an example use case, let this driver autoprobe
for that as well. If it is present, modprobing ltc2990 is sufficient.
The property_entry enables the three additional inputs available on
this particular board:
in1 will be the voltage of the 5V rail, divided by 2.
in2 will be the voltage of the 12V rail, divided by 4.
temp3 will be measured using a PCB loop next the chip.

It connects a PCF8584 I2C controller to the Zorro bus, providing I2C

*** 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.

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.

- 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

Merge tag 'libnvdimm-fixes-5.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm fixes from Dan Williams:
"A collection of locking and async operations fixes for v5.3-rc2. These
had been soaking in a branch targeting the merge window, but missed
due to a regression hunt. This fixed up version has otherwise been in
-next this past week with no reported issues.
In order to gain confidence in the locking changes the pull also
includes a debug / instrumentation patch to enable lockdep coverage
for libnvdimm subsystem operations that depend on the device_lock for
exclusion. As mentioned in the changelog it is a hack, but it works
and documents the locking expectations of the sub-system in a way that
others can use lockdep to verify. The driver core touches got an ack
from Greg.
Summary:
- Fix duplicate device_unregister() calls (multiple threads competing
to do unregister work when scheduling device removal from a sysfs
attribute of the self-same device).
- Fix badblocks registration order bug. Ensure region badblocks are
initialized in advance of namespace registration.
- Fix a deadlock between the bus lock and probe operations.
- Export device-core infrastructure to coordinate async operations
via the device ->dead state.
- Add device-core infrastructure to validate device_lock() usage with
lockdep"
