The Nova Lake platform enhances THC with half divider capability for
clock division, allowing more granular frequency control for the THC

Supported frequencies include 50MHz (125MHz/2.5), 35MHz (125MHz/3.5),
and 10MHz (125MHz/8/1.5).

HID: Intel-thc-hid: Intel-quicki2c: Add output report support
Add support for HID output reports in the intel-quicki2c driver by
implementing the output_report callback in the HID low-level driver
interface.
This enables proper communication with HID devices that require
output report functionality, such as setting device configuration or
updating device firmware.

HID: Intel-thc-hid: Intel-quicki2c: Support writing output report format
There are two output formats requested in the HID-over-I2C specification:
- Command format (set feature/set report): encoded command written to
command register, followed by data written to data register
- Output report format: all data written directly to output register
Current quicki2c_init_write_buf() implementation only supports the
command format.
Extend quicki2c_init_write_buf() to automatically detect the output
format based on the presence of command parameters and prepare the
appropriate output buffer accordingly.

HID: intel-thc-hid: Intel-quickspi: switch first interrupt from level to edge detection
The original implementation used level detection for the first interrupt
after device reset to avoid potential interrupt line noise and missed
interrupts during the initialization phase. However, this approach
introduced unintended side effects when tested with certain touch panels,
including:
- Delayed hardware interrupt response
- Multiple spurious interrupt triggers
Switching back to edge detection for the first interrupt resolves these
issues while maintaining reliable interrupt handling.
Extensive testing across multiple platforms with touch panels from
various vendors confirms this change introduces no regressions.

HID: intel-thc-hid: intel-quicki2c: support ACPI config for advanced features
There is a new BIOS enhancement that adds the capability to configure the
following two features of I2C subsystem introduced in commit 1ed0b48
("Intel-thc: Introduce max input size control") and commit 3f2a921
("Intel-thc: Introduce interrupt delay control"):
- Max input size control
- Interrupt delay control
As BIOS is used for the configuration of these two features, change driver
data usage to indicate hardware capability, and add corresponding ACPI
configuration support in QuickI2C driver.
