Add compatible for ti,am654-timer to support the timers. For example, am654
has four timers in the MCU domain and 12 timers in the MAIN domain.

Let's make timer-ti-dm selectable for ARCH_K3, and add a separate option
for OMAP_DM_SYSTIMER as there should be no need for it on ARCH_K3.
For older TI SoCs, we are already selecting OMAP_DM_TIMER in
arch/arm/mach-omap*/Kconfig. For mach-omap2, we need to now also select
OMAP_DM_SYSTIMER.

The __omap_dm_timer_* inline functions in the header are no longer needed
outside the driver, and the header ifdefs prevent the driver working for
ARCH_K3.
Let's move the inline functions to the driver and drop the ifdefs and
drop the unused functions __omap_dm_timer_override_errata() and
__omap_dm_timer_load_start().

Extend aquacomputer_d5next driver to expose hardware temperature sensors
and fans of the Aquacomputer Quadro fan controller, which communicates
through a proprietary USB HID protocol. Implemented by Jack Doan [1].
Four temperature sensors and PWM controllable fans are available. The
liquid flow sensor is also exposed, implemented by Leonard Anderweit [2].
Additionally, serial number, firmware version and power-on count are
exposed through debugfs.
This driver has been tested on x86_64.

Drivers tend to want to define the names of their regulators somewhere
in their source file as "static const". This means, inevitable, that
every driver out there open codes something like this:
static const char * const supply_names[] = {
"vcc", "vccl",
};
static int get_regulators(struct my_data *data)
{
int i;
data->supplies = devm_kzalloc(...)
if (!data->supplies)
return -ENOMEM;
for (i = 0; i < ARRAY_SIZE(supply_names); i++)
data->supplies[i].supply = supply_names[i];
return devm_regulator_bulk_get(data->dev,
ARRAY_SIZE(supply_names),
data->supplies);
}
Let's make this more convenient by doing providing a helper that does
the copy.
I have chosen to have the "const" input structure here be the exact
same structure as the normal one passed to
devm_regulator_bulk_get(). This is slightly inefficent since the input
data can't possibly have anything useful for "ret" or consumer and
thus we waste 8 bytes per structure. This seems an OK tradeoff for not
introducing an extra structure.

There are a number of drivers that follow a pattern that looks like
this:
1. Use the regulator bulk API to get a bunch of regulators.
2. Set the load on each of the regulators to use whenever the
regulators are enabled.
Let's make this easier by just allowing the drivers to pass the load
in.
As part of this change we need to move the error printing in
regulator_bulk_get() around; let's switch to the new dev_err_probe()
to simplify it.

STM32G0 comes with STM32 bootloader in its system memory. Add support
for some I2C bootloader commands as described in application notes
AN2606 and AN4221, to enable STM32G0 UCSI firmware update.
Upon probing, the driver needs to know the STM32G0 state:
- In bootloader mode, STM32 G0 answers at i2c addr 0x51.
- In running mode, STM32 G0 firmware may answer at two address.
- The main address specified in DT is used for UCSI.
- 0x51 addr can be re-used for FW controls like getting software version
or jump to booloader request.
So probe using the main firmware i2c address first, before attempting
bootloader address (e.g. check for blank, erased or previously aborted
firmware update).

STM32G0 provides an integrated USB Type-C and power delivery interface.
It can be programmed with a firmware to handle UCSI protocol over I2C
interface. A GPIO is used as an interrupt line.
Type-C connector can be used as a wakeup source (typically to detect
changes on the port, like attach or detach). PM suspend / resume routines
are used to enable wake irqs, and signal a wakeup event in case the IRQ
has fired while in suspend. The i2c core is doing the necessary
initialization when the "wakeup-source" flag is provided.
Note: the interrupt handler shouldn't be called before the i2c bus resumes.
So, the interrupts are disabled during suspend period, and re-enabled
upon resume, to avoid i2c transfer while suspended, from the irq handler.

The fwnode_connection_find_match() function handles two cases: named
references and graph endpoints. In the second case, the match function
passed in is called with the id to check for the match. However, the
match function for the recently added type-c retimer class assumes the
connection has already been matched (which is only true for the first
case).
The result is that with that change, all type-c nodes with graph
endpoints defer probe indefinitely, independently of having a retimer
connection or not.
Add the missing check, like is done by the type-c mux and usb role
switch code, to fix the issue.

does so without acquiring the udc_lock mutex, which protects this

uevent processing, the driver structure may be accessed after it has
been deallocated.
To prevent the race, we make sure that the routine holds the mutex
around the racing accesses.

Usb core introduce the mechanism of giveback of URB in tasklet context to
reduce hardware interrupt handling time. On some test situation(such as
FIO with 4KB block size), when tasklet callback function called to
giveback URB, interrupt handler add URB node to the bh->head list also.
If check bh->head list again after finish all URB giveback of local_list,
then it may introduce a "dynamic balance" between giveback URB and add URB
to bh->head list. This tasklet callback function may not exit for a long
time, which will cause other tasklet function calls to be delayed. Some
real-time applications(such as KB and Mouse) will see noticeable lag.
In order to prevent the tasklet function from occupying the cpu for a long
time at a time, new URBS will not be added to the local_list even though
the bh->head list is not empty. But also need to ensure the left URB
giveback to be processed in time, so add a member high_prio for structure
giveback_urb_bh to prioritize tasklet and schelule this tasklet again if
bh->head list is not empty.
At the same time, we are able to prioritize tasklet through structure
member high_prio. So, replace the local high_prio_bh variable with this
structure member in usb_hcd_giveback_urb.

Since commit 4736ebd7fcaff1eb8481c140ba494962847d6e0a ("usb: host:

This is a minor bug which means that certain error messages are not
printed.
The devm_gpiod_get_optional() function can return either error pointers
or NULL. It returns error pointers if there is an allocation failure,
or a similar issue. It returns NULL if no GPIO was assigned to the
requested function. Print an error in either case.
The gpiod_to_irq() function never returns zero. It either returns
a positive IRQ number or a negative error code.

There is no need to store the result of the & operation back to the
variable var. The store is redundant, replace &= with just &.
