2022-07-16ec/system76/ec: Provide charging thresholds by defaultTim Crawford
Battery charging thresholds are a firmware implementation and not dependent on any hardware. It is expected that all boards using System76 EC firmware will select this option, so enable it by default. Leave it disabled on clevo/cml-u, which didn't have it selected.

2021-11-23ec/system76/ec: acpi: Add dGPU thermal reportingJeremy Soller
Add a new config for boards with dGPUs to enable reporting fan duty and temperature. The dGPU is not yet enabled on any boards, so it always reports the temp as 0. However, the EC firmware does use the dGPU's fan and so reports valid information for fan speed.

2020-09-07ec/system76: Add console supportJeremy Soller
This adds support for line-buffered console output to System76 EC firmware. Once the print command is received, the EC firmware multiplexes the output to any enabled console on the EC. This can be a memory ringbuffer, a parallel port (using the keyboard connector), or i2c (using the battery connector). Once the entire buffer is sent, it sets the command register to 0, indicating completion. For more information, please see: https://github.com/system76/ec/blob/master/doc/debugging.md Tested on system76/lemp9 with CONSOLE_SYSTEM76_EC enabled.
