Hi Marek,

I'm the committer of "ilitek_ts_i2c.c" driver.
The so-called "Lego" series was listed below, as listed in ilitek_ts_i2c.yaml
It's the newer series with different protocol and control flow to ILITEK IC FW.

- ilitek,ili2130
- ilitek,ili2131
- ilitek,ili2132
- ilitek,ili2316
- ilitek,ili2322
- ilitek,ili2323
- ilitek,ili2326
- ilitek,ili2520
- ilitek,ili2521

> The older driver also supports 251x . What exactly is "Lego" series ?
More specifically, Lego series support "252x", not "2510".
The older driver support 210x and 251x, which has older protocol.

> In fact, is there documentation for the different ILI2xxx touchscreen controllers ? So far, all the information I had was pulled from the various forks of downstream example code.
If it need for a doc. to distinguish it, I am glad to support/arrange, and where should I put those description to ?
