In esp32p4, the MCPWM has a new feature, mainly ETM-oriented.
Each operator has two event comparators, can generate an event
when the count value of the timer that operator connects is equal
to the value of event comparator.
MCPWM group clock pre scale was originally fixed to 2, which is
inconvenient. Set group clock prescale dynamically. Now the maximum
resolution of the MCPWM timer is up to 160MHz(when the prescale set
to 1). And add a resulotion config for MCPWM capture.
The default zero input gpio num is 0. Users need to set it additionally
when not use zero input signal. It may become a breaking change.
Add an enable flag to avoid it.
The MCPWM carrier is part of the operator and can work independently
without the MCPWM timer being enabled. This commit add the MCPWM
carrier clk source.
Each MCPWM operator has two Trigger (named T0 and T1), and they can be
routed to GPIO fault signal or timer sync event.Generator can be set up
to perform different action on Trigger event.
This commit add a trigger driver and a test for the driver.
Now the soc interrupts definitions are scattered around in the esp-idf
which are out of sync. Put interrupts definitions in soc/periph_defs.h
(!ESP32) or soc/soc.h(ESP32) together in soc/interrupts.h.
There are some register description errors in parts of rom/gpio.h
This commit update the incorrect comments in rom/gpio.h And now
esp_rom_gpio.h is recommend instead of rom/gpio.h. So this commit adds
macro SIG_GPIO_OUT_IDX in esp_rom_gpio_connect_out_signal
function and removes the reference to gpio.h in some source files.

since the linker placement of the hal functions are controlled by the Kconfig in the driver component,
we should create the linker.lf in the driver component, not in the hal component.
with esp_rom_delay_us in test_apps
This commit replaces vTaskDelay with esp_rom_delay_us in the gptimer
driver. The former function can introduce millisecond jitter due to
OS task switching, while the latter has less jitter because of the
polling delay. Therefore this commit reduces the delta values for
various timer tests.
Changes made in this commit include:
- Replacing vTaskDelay with esp_rom_delay_us
- Adjusting delta values for various timer tests
The caches are disabled when reading/writing/erasing flash.
All CPUs should always execute code and access data from internal RAM.
Add an IRAM option to enhance the performance of LEDC.
