Support for ESP32-C61

Is your feature request related to a problem?

As announced new SoC by Espressif: https://www.espressif.com/en/news/ESP32-C61_SoC

Describe the solution you'd like

Please add support for the PSRAM in the ESP32-C61 (as of now the only in the C-series with PSRAM)

Describe alternatives you've considered

I have checked existing list of Feature requests and the Contribution Guide

• Chip and modules must be first produced
• Support needs to be added to ESP-IDF
• Arduino needs to start tracking the IDF version that has support

When the above becomes reality, we can add support for it :)

Gimme!

Hmm why can't we do "DDD" (Demand Driven Development), so we implement support for a not even announced chip and Espressif will follow our implementation :)

J/K of course.
I think 2024 will be a busy year for implementing support of all already announced products but with no silicon yet (ESP32-C5 / P4 / C61 / H2
Now with the well structured ESP-IDF 5.x it has become a lot simpler to implement support for a new platform.

Ah is there some test silicon available?

Hello @TD-er,

thanks for opening a ticket, you are fast! :)

We will start first with ESP32-P4, it will be fully supported by ESP-IDF v5.3, which will be released at the middle of this year. We will soon open an issue to track progress on ESP32-P4.

ESP32-C5 & ESP32-C61 will have preview support in ESP-IDF v5.3 and full support in v5.4 so there is still time to start working on it and we do not have HW yet.

I hope it will answer your questions.

I have assigned this task to 3.2.0 milestone.
