The only open question is on how to handle the incompatibility with the Framework-specific commands. But the currently implemented solution is the most safe one; so in my opinion this series could be applied as is and then we can always relax that restriction later. --- Add a power supply driver that supports charge thresholds and behaviour configuration. This is a complete rework of "platform/chrome: cros_ec_framework_laptop: new driver" [1], which used Framework specific EC commands. The driver propsed in this series only uses upstream CrOS EC functionality. Tested on a Framework 13 AMD, Firmware 3.05. This driver should go through the chrome-platform tree. Otherwise "platform/chrome: cros_ec_proto: Introduce cros_ec_cmd_versions()" will conflict with commit a14a569a9918 ("platform/chrome: cros_ec_proto: Introduce cros_ec_cmd_readmem()") from chrome-platform/for-next. The patch "platform/chrome: cros_ec_proto: Introduce cros_ec_cmd_versions()" is also part of my series "hwmon: (cros_ec): fan target, fan pwm control and temperature thresholds"[2]. To be useful, this series depends on commit 08dbad2c7c32 ("mfd: cros_ec: Register charge control subdevice") from the MFD tree [0]. Based on chrome-platform/for-next.
