* hwmon: (oxp-sensors) Move tt_toggle attribute to dev_groupsJoaquín Ignacio Aramendía2023-07-181-14/+24
| | | | | | | | | | | | | | A driver should not be manually adding groups in its probe function (it will race with userspace), so replace the call to devm_device_add_groups() to use the platform dev_groups callback instead. This will allow for removal of the devm_device_add_groups() function.

* hwmon: (oxp-sensors) Add tt_toggle attribute on supported boardsJoaquín Ignacio Aramendía2023-06-171-1/+133
| | | | | | | | | | | | | | | | | | | | | | | | OneXPlayer boards from the last generation (both for OneXPlayer and AOK ZOE brands) have a toggle in the EC to switch the "Turbo/Silent" button into a different keyboard event. Add a means to use that "Turbo button takeover" function and expose it to userspace in a custom sysfs `tt_toggle` attribute. It can be read to take the current state. Write 1|0 to activate the function. The specific keycode is dependent on the board but can be checked by running `evtest` utility. Newer BIOS on the OneXPlayer added this function aside from string changes. Add a board enum to differentiate it from the old OneXplayer Mini AMD BIOS. Currently known supported boards: - AOK ZOE A1 - OneXPlayer Mini AMD (only newer BIOS version supported) - OneXPlayer Mini Pro Signed-off-by: Joaquín Ignacio Aramendía <samsagax@gmail.com> Link: https://lore.kernel.org/r/20230611143332.40590-2-samsagax@gmail.com Signed-off-by: Guenter Roeck <linux@roeck-us.net>
* hwmon: (oxp-sensors) Stop passing device structureJoaquín Ignacio Aramendía2023-06-081-8/+8
| | | | | | | | | | | We don't need to pass device structure to write_to_ec() so we remove that from the function declaration. The same is valid for pwm_enable() and pwm_disable() as we were passing the pointer to hand it off to write_to_ec().

* hwmon: (oxp-sensors) Add AYANEO AIR and AIR ProDerek J. Clark2023-02-031-9/+43
| | | | | | | | | | | | | | | | | | | | | | Add support for the AYANEO AIR and AYANEO AIR Pro models of handheld devices. These devices use the same EC registers and logic as the One X Player mini AMD. Previous AYANEO models are not supported as they use a different EC and do not have the necessary fan speed write enable and setting registers. The driver is tested on AYANEO AIR while AIR Pro model EC functionality and DMI data were verified using command line tools by another user. Add: - AYANEO AIR (AMD 5560U) - AYANEO AIR Pro (AMD 5560U) - AYANEO AIR Pro (AMD 5825U) While at it, fix spelling error (appart -> apart).

* hwmon: add OneXPlayer mini AMD sensors driverJoaquín Ignacio Aramendía2022-12-041-0/+256
Sensors driver for OXP Handhelds from One-Netbook that expose fan reading and control via hwmon sysfs. As far as I could gather all OXP boards have the same DMI strings and they can be told appart only by the boot cpu vendor (Intel/AMD). Currently only AMD boards are supported since Intel have different EC registers and values to read/write. Fan control is provided via pwm interface in the range [0-255]. AMD boards have [0-100] as range in the EC, the written value is scaled to accommodate for that.
