Add support for configuring the SysTick clock source via devicetree
using a new `clock-source` property. This allows selecting between
the external reference clock (0) and the processor clock (1).
Previously, the driver always set the CLKSOURCE bit, forcing the use
of the processor clock. This change introduces a helper function
`systick_ctrl_clksource_flag_from_dt()` that reads the devicetree
property and returns the appropriate CTRL register flag.
The CTRL register is now programmed deterministically using direct
assignment instead of `|=` to ensure the CLKSOURCE bit is properly
cleared when switching to external clock, preventing potential
interrupt storms when CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC reflects
the external clock rate.
If the property is absent, the driver defaults to legacy behavior
(processor clock).

The LCD_CAM peripheral is a parallel I/O controller integrated in the ESP32
series. It consists of an LCD output module and a DVP camera input module.
The camera side is already supported in Zephyr as a video driver.
This commit adds support for the LCD module by implementing it as a
MIPI-DBI backend. The LCD_CAM supports multiple output formats, and the
initial implementation provides I8080 mode.

Move the shared pinctrl and clock initialization for the LCD_CAM peripheral

GPIO hardware in Microchip MEC parts is the same except for the MUX
field (number of alternate functions). We modify the old XEC PINCTRL
driver to work on all MEC parts and also be independent of HAL and
CMSIS register structures. During development we found a DT issue
with DT_ENUM_IDX_OR always inserting the default value. Worked around
by converting slew rate and drive strength to YAML integer type and
created defines for the values in the dt-bindings header.

Allow alarm_cfg->ticks to be 0 for immediate callback execution.
When ticks equals 0, set the interrupt pending instead of returning
-EINVAL, causing the ISR to fire immediately.
Implementation:
- Add irq_set_pending()/irq_is_pending() helpers for NVIC and GIC
- Store IRQ number in device config for pending operations
- Refactor timer state handling to eliminate duplication
- Update get_pending_int() to check both HW flags and NVIC/GIC state
This supports idle timer use cases where sleep duration may be zero
and eliminates the need for special-case handling in application code.

Add device tree property to configure LPTMR free-running mode instead
of hardcoding it to disabled.
The freerunning property controls counter reset behavior:
- If false (default): Counter resets after compare match
- If true: Counter resets only on overflow, continues after compare
This allows per-instance configuration of the LPTMR timer mode based
on application requirements without code changes.

Implement eeprom_target_program() using eeprom_target_write_data() and

The current functions to access the EEPROM data are not ideal, E.G.:
- eeprom_target_program() is hard coded to write to the beginning of the
EEPROM data
- eeprom_target_read() reads a single byte, so large overhead to read all
data
So as an alternative, add an interface similar to what is provided by
zephyr/drivers/eeprom.h, E.G. functions taking an offset and and length.
Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
For some use cases it can be interesting to know when the eeprom has been
written to by the I2C host (E.G. once a stop has been received after a
write transaction), so add a "changed" callback.
Multiple EEPROM instances are supported, so pass the device and user data
as arguments to the callback.

When transceive is called on a chip without CONFIG_SPI_STM32_INTERRUPT,

will free memory and disable the peripheral. However, when triggering

are cleared and we leak application memory.
