2024-08-27power: supply: max77693: Expose input current limit and CC current propertiesArtur Weber1-0/+52

2024-08-27power: supply: max17042_battery: Fix SOC threshold calc w/ no current senseArtur Weber1-1/+4
Commit 223a3b82834f ("power: supply: max17042_battery: use VFSOC for capacity when no rsns") made it so that capacity on systems without current sensing would be read from VFSOC instead of RepSOC. However, the SOC threshold calculation still read RepSOC to get the SOC regardless of the current sensing option state. Fix this by applying the same conditional to determine which register should be read. This also seems to be the intended behavior as per the datasheet - SOC alert config value in MiscCFG on setups without current sensing is set to a value of 0b11, indicating SOC alerts being generated based on VFSOC, instead of 0b00 which indicates SOC alerts being generated based on RepSOC. This fixes an issue on the Galaxy S3/Midas boards, where the alert interrupt would be constantly retriggered, causing high CPU usage on idle (around ~12%-15%).

The pwm1_enable attribute of the pwmfan driver influences the mode of operation, especially in case of a requested pwm1 duty cycle of zero. Especially setting pwm1_enable to two, should keep the pwm controller enabled even if the duty cycle is set to zero [1].

Add support for the OrangePi NEO-01. It uses different registers for PWM manual mode, set PWM, and read fan speed than previous devices. Valid PWM input and duty cycle is 1-244, we scale this from 1-255 to maintain compatibility with the existing interface. Add OneXPlayer 2 series, OneXFly, and X1 series models. The 2/X1 series use new registers for turbo button takeover and read fan speed. X1 has an Intel variant so change the CPU detection at init to only check for the affected devices. While at it, adjust formatting of some constants and reorder all cases alphabetically for consistency. Rename OXP_OLD constants to OXP_MINI for disambiguation. Update code comments for clarity.
