[hub75] Update documentation

[stuartparmenter]

Description:

• esp32-trinity was supported originally but missed from docs
• C6 was never properly supported (code is in the library, but it tries to use PSRAM and there is no PSRAM on the C6. The parlio implementation is memory heavy and is maybe not practical to actually support, but tbd).
• Expand bit depth for 0.2.1 update

• [hub75] Bump esp-hub75 version to 0.2.2 esphome#12674

Checklist:

• I am merging into next because this is new documentation that has a matching pull-request in esphome as linked above.
  or

• I am merging into current because this is a fix, change and/or adjustment in the current documentation and is not for a new component or feature.

• Link added in /components/_index.md when creating new documents for new components or cookbook.

New Component Images

If you are adding a new component to ESPHome, you can automatically generate a standardized black and white component name image for the documentation.

To generate a component image:

1. Comment on this pull request with the following command, replacing component_name with your component name in lower_case format with underscores (e.g., bme280, sht3x, dallas_temp):

   @esphomebot generate image component_name
   

2. The ESPHome bot will respond with a downloadable ZIP file containing the SVG image.

3. Extract the SVG file and place it in the /static/images/ folder of this repository.

4. Use the image in your component's index table entry in /components/_index.md.

Example: For a component called "DHT22 Temperature Sensor", use:

@esphomebot generate image dht22

Walkthrough

This PR updates ESPHome documentation across multiple components, standardizing frequency parameter types from int/float to frequency, introducing new platform support (BK72xx in deep_sleep, UART events), adding new configuration options (ESP32 OTA rollback, HUB75 brightness action), and refactoring the sprinkler component to use H-Bridge switch control. It also updates version information and release note generation tooling.

Changes

Cohort / File(s)	Summary
Frequency Type Standardization content/components/at581x.md, content/components/canbus/mcp2515.md, content/components/esp32_camera.md, content/components/i2c.md, content/components/output/esp8266_pwm.md, content/components/output/ledc.md, content/components/output/libretiny_pwm.md, content/components/output/pca9685.md, content/components/sensor/ade7880.md, content/components/sx126x.md, content/components/sx127x.md	Updated parameter type annotations from int/float to frequency enum; preserved valid values and defaults. Includes clock field in MCP2515 and frequency parameter updates across multiple output and sensor components.
Frequency Display Format Updates content/components/libretiny.md, content/components/output/ledc.md, content/components/packet_transport/sx12*.md, content/components/servo.md, content/components/sx12*.md	Converted frequency display format from numeric Hz (e.g., 433920000) or "X Hz" to human-readable units (433.92MHz, 1kHz). Affects example configurations and parameter descriptions.
New Platform Support & Events content/components/_index.md, content/components/deep_sleep.md, content/components/event/uart.md	Added UART event documentation; expanded deep_sleep to support BK72xx with timer/pin wakeup (up to 36 hours), multi-pin wakeup configuration, and platform-specific examples.
HUB75 Display Component content/components/display/hub75.md	Added new hub75.set_brightness action; introduced esp32-trinity board preset and updated Apollo Automation M1 revision labels; expanded bit_depth range from 6–12 to 4–12; added driver compatibility and pin usage notes; removed ESP32-C6 from supported variants.
ESP32 & Platform Configurations content/components/esp32.md, content/components/http_request.md, content/components/mqtt.md, content/components/speaker/resampler.md, content/components/spi.md	Added optional enable_ota_rollback to ESP32 Advanced Configuration; clarified SSL/TLS support is ESP32-specific in HTTP request; updated MQTT TLS documentation from esp-idf to ESP32-wide terminology; removed ESP-IDF conditional from resampler task_stack_in_psram; changed "ESP-IDF limit" to "ESP32 limit" in SPI.
Sensor Component Updates content/components/sensor/bme68x_bsec2.md, content/components/sensor/hm3301.md, content/components/sensor/mmc5603.md, content/components/sensor/pmsx003.md	Added optional id field to bme68x_bsec2; expanded hm3301 Air Quality documentation with AQI/CAQI standards and smoothing filter examples; corrected mmc5603 branding (MMC5693→MMC5603) and added auto_set_reset configuration option; introduced AQI configuration for pmsx003 with calculation types and scales.
Sprinkler Component Refactoring content/components/sprinkler.md	Migrated from individual pump/valve on/off switch pairs to unified H-Bridge switch control; removed pulse_duration options; refactored examples to use pump_switch_id and valve_switch_id with H-Bridge switches; updated board value (featheresp32→esp32dev); revised narrative and cross-references to reflect new architecture.
Update Component & Version Management content/components/update/_index.md, data/version.yaml, script/generate_release_notes.py	Added new update.check Action to trigger update checks without installation; bumped version to 2026.1.0-dev; refactored release notes script to generalize PR collection across multiple release types via new _collect_prs_from_tags() and _get_previous_release_prs() methods to exclude previously-released PRs.

Pre-merge checks and finishing touches

✅ Passed checks (3 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title '[hub75] Update documentation' is specific to the main changes (hub75 component documentation updates) but incompletely describes the changeset, which includes 30+ files with frequency type updates, new UART event component, and version bumps.
Description check	✅ Passed	The PR description clearly explains hub75-specific changes (esp32-trinity support, C6 removal, bit_depth expansion) and is directly related to the changeset, though it does not address all 30+ other files modified.
Docstring Coverage	✅ Passed	Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%.
