## Summary
<!-- This field should contain a summary of the changes. It will be
pre-filled with the commit's message and descriptions. Adjust it accordingly -->
* arch/risc-v/espressif: Fix CMake build issues for new peripheral support
Fix CMake build issues
## Impact
<!-- Please fill the following sections with YES/NO and provide a brief
explanation -->
Impact on user: Yes, analog comparator support added
<!-- Does it impact user's applications? How? -->
Impact on build: No
<!-- Does it impact on building NuttX? How? (please describe the required
changes on the build system) -->
Impact on hardware: Yes, analog comparator support added
<!-- Does it impact a specific hardware supported by NuttX? -->
Impact on documentation: Yes, related docs added
<!-- Does it impact the existing documentation? Please provide additional
documentation to reflect that -->
Impact on security: No
<!-- Does it impact NuttX's security? -->
Impact on compatibility: No
<!-- Does it impact compatibility between previous and current versions? Is
this a breaking change? -->
## Testing
<!-- Please provide all the testing procedure. Consider that upstream
reviewers should be able to reproduce the same testing performed internally -->
- Analog Comparator
Config used:
```
esp32p4-function-ev-board:analog_cmpr
esp32h2-devkit:analog_cmpr
```
With these options added into defconfig:
```
CONFIG_DEBUG_ANALOG
CONFIG_DEBUG_ANALOG_ERROR
CONFIG_DEBUG_ANALOG_INFO
CONFIG_DEBUG_ANALOG_WARN
CONFIG_DEBUG_FEATURES
```
- Touch Sensor
`esp32p4-function-ev-board:buttons` config used with these options (added
into defconfig)
```
CONFIG_ESPRESSIF_TOUCH=y
CONFIG_ESP_TOUCH_CHANNEL1=y
CONFIG_ESP_TOUCH_IRQ=y
```
### Building
<!-- Provide how to build the test for each SoC being tested -->
Command to build:
- Analog Comparator
```
ntxbuild start esp32p4-function-ev-board analog_cmpr --use-cmake && ntxbuild
build && ESPTOOL_PORT=/dev/ttyUSB0 cmake --build build -t flash
```
- Touch Sensor
```
ntxbuild start esp32p4-function-ev-board buttons --use-cmake && ntxbuild
build && ESPTOOL_PORT=/dev/ttyUSB0 cmake --build build -t flash
```
### Running
<!-- Provide how to run the test for each SoC being tested -->
- Analog Comparator
SRC pin of comparator (GPIO52->P4 GPIO11->H2) connected to GND at first,
after that pin connected to 3v3
Snippet used to test is looking like this:
```
#include <nuttx/config.h>
#include <nuttx/analog/comp.h>
#include <inttypes.h>
#include <stdio.h>
#include <fcntl.h>
#include <unistd.h>
#include <syslog.h>
#include <sys/types.h>
#include <sys/ioctl.h>
#include <stdlib.h>
#include <string.h>
#include <errno.h>
#include <debug.h>
#include <driver/gpio.h>
int main(int argc, FAR char *argv[])
{
int fd;
int ret;
int res;
fd = open("/dev/anacmpr0", O_RDONLY);
while(1)
{
ret = read(fd, &res, sizeof(res));
if (ret != 0)
{
printf("Result: %ld\n", res);
}
}
ret = read(fd, &res, sizeof(res));
return OK;
}
```
- Touch Sensor
`buttons` example run and then touched to the GPIO2 pin
### Results
<!-- Provide tests' results and runtime logs -->
Output:
- Analog Comparator
```
nsh> ls /dev
/dev:
anacmpr0
...
nsh> custom_app
Result: 0
esp_ana_cmpr_callback: Comparator unit0: Positive cross event triggered
Result: 1
esp_ana_cmpr_callback: Comparator unit0: Negative cross event triggered
Result: 0
```
- Touch Sensor
Output should look like this:
```
nsh> buttons

board_buttons: Reading button 0
board_buttons: b=0 n=0
board_buttons: Reading button 1
