Mainline component status
Element type | Element | Works? | Notes |
---|---|---|---|
Chipset | Exynos 4412 | ||
Graphics | Mali-400MP4 | ||
PMIC (Regulators) | max77686 | Supported in mainline | |
Fuel gauge | MAX17040 | Supported by MAX17042 driver | |
Charger | MAX8903 | Supported in mainline (though no other DTSes use it yet...) | |
Touchscreen | Focaltech ft5x0x or Atmel MXT1664S | Atmel supported, Focaltech unclear (need exact model number, but should be supported by edt-ft5x06 driver?) | |
Display | LTL101AL03 | Not in mainline, but should be simple to implement | |
Backlight | PWM backlight | Can use the pwm-backlight driver. | |
Buttons | gpio-keys | Volume up/down and power button. | |
Audio | WM8985 | The codec itself is supported but we might need more to get it to work | |
Camera | ON Semiconductor AS0260 | Not in mainline, | |
GPS | UBLOX G6010 | Not in mainline | |
Accelerometer | Bosch BMA150 | Supported in mainline. Oddly enough, downstream handles it in some Yamaha-related driver (grep for YAS_ACC_DRIVER), drivers/input/misc/yas_cfg.h | |
Magnetometer | Alps HSCDTD007/008 | Downstream sources initially led to Yamaha YAS530, grep for YAS_MAG_DRIVER, drivers/input/misc/yas_cfg.h; but dmesg claims HSCDTD007/008. Either way, supported in mainline. | |
Light sensor | ISL29023 | Supported in mainline by ISL29018 driver |
Some parts of this have been verified with a MEHMET_HW_VE1 [0x7] revision tablet.
