SX9324 driver is updated per Linux's documentation found at
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/iio/proximity/semtech,sx9324.yaml
Supporting logic for the deprecated SX932x driver is hence guarded by
DRIVERS_I2C_SX9324_SUPPORT_LEGACY_LINUX_DRIVER
This patch by itself does not introduce functional changes to any board.
The legacy SX932x Linux driver never reached upstream Linux and is only
available in ChromeOS kernel fork of 4.4 and 5.4. Linux later accepted
a different implementation named SX9324 and has been available since
5.4. Ideally all variants should adopt the new driver; however, during
the transition phase, coreboot must support both drivers. It is better
to have a single firmware build that can work with both Linux kernel
drivers by specifying both sets of properties. Legacy driver support
should be deleted once all variants finish migration.
BUG=b:242662878
TEST=Dump ACPI SSDT then verify _DSD entries related to the legacy
SX932x driver are identical w/ and w/o this patch

using ti50 (such as corsola). Therefore, introduce a new Kconfig option
'GOOGLE_TPM_IRQ_TIMEOUT_MS'.
For platforms using cr50, we need to support legacy pre-ready-IRQ cr50
factory images during the initial boot, so the timeout remains 100ms for
I2C TPM and 10ms for SPI TPM. For all the other platforms using ti50,
the default timeout is increased to 750ms, as suggested by the ti50 team

This is useful for boards which may utilize touchpads/touchscreens from
multiple vendors, so that only the device(s) present are added to the
SSDT. This relieves the burden from the OS to detect/probe if a device
is actually present and allows the OS to trust the ACPI _STA value.

This patch introduces CONFIG_I2C_TRANSFER_TIMEOUT_US,
which controls how long to wait for an I2C devices to
produce/accept all the data bytes in a single transfer.
(The device can delay transfer by stretching the clock of
the ack bit.)
The default value of this new setting is 500ms. Existing
code had timeouts anywhere from tens of milliseconds to a
full second beween various drivers. Drivers can still have
their own shorter timeouts for setup/communication with the
I2C host controller (as opposed to transactions with I2C
devices on the bus.)
In general, the timeout is not meant to be reached except in
situations where there is already serious problem with the
boot, and serves to make sure that some useful diagnostic
output is produced on the console.

Introduce firmware-power-managed DSD ACPI property for TPM devices.
This property can be checked by the kernel TPM driver to override how
the TPM power states are managed. This is a tri-state flag, true,
false, or unset. So an enum used to keep the flag is unset by default.
When firmware-power-managed is true, the kernel driver will not send a
shutdown during s2idle/s0i3 suspend.

Move bcd2bin() / bin2bcd() functions to commonlib/bsd/include/
Also, the license is changed from GPL to BSD.
This is because it is needed from "utils" (see CL in the chain).
For reference bin2bcd() & bcd2bin() are very simple functions.
There are already BSD implementations, like these ones (just to
name a few):

Since the OS provides its own driver for the I2C controller it can
choose to use a bus speed other than the one used at coreboot runtime.
In this case it would be good to provide a way how the needed bus
timings are communicated to the OS, since these are very board-specific
and there is no way that the OS can know them other than read the
appropriate ACPI reported timings.
This patch adds some code to report additional bus speed timings if
there are some defined in the devicetree.

In commit b64db833d6 a basic ACPI support was added to the driver.
With this support an SSDT-entry is created for this RTC and it is now
visible to the OS via ACPI. In Linux the PNP-devices, which are
reported over ACPI, are scanned rather early and if the entry is found,
the device is claimed even if there is no driver available yet.
In this case, when the native RTC-driver without ACPI-support is loaded
and tries to register this device, the RTC is already blocked by the
PNP-drivers and cannot be used anymore. This leads to a non-usable RTC
on kernels where the needed ACPI-extension is not yet merged into the
RTC driver.
This patch provides a way to disable the ACPI-support for the RTC if
needed.

HSBIAS_SENSE_EN configures HSBIAS output current sense through
the external 2.21-k resistor. HSBIAS_SENSE is hardware feature to reduce
the potential pop noise during the headset plug out slowly. But on some
platforms ESD voltage will affect it causing test to fail, especially
with CTIA headset type. For different hardware setups, a designer might
want to tweak default behavior.
