Element type Element Works? Notes
Chipset Exynos 4412 Y
Graphics Mali-400MP4 Y
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.
