The device has 2 modes. The first one is an emulation of a touchscreen
by sending left and right button, and the second mode is the one used in
dual-touch (sending trackingID, touch and else).

In case of a suspend/resume, the device switch back to the first mode
described above (with left and right buttons).
This adds a hook in .reset_resume for the device to be switched to
the correct mode (I just copied the code in mosart_probe).

This commit allows the device to be recognized as a touchscreen, and not a
touchpad by xf86-input-evdev.

The device has 2 modes. The first one is an emulation of a touchscreen by
sending left and right button, and the second mode is the one used in
dual-touch (sending trackingID, touch and else).

That's why there is a hid report containing left and right buttons
(9000001 and 9000002). The point is that xorg relies on these fields to
determine if it's a touchpad or a touchscreen.
Clearing the report (return -1) makes xorg detecting it out of the box
as a quite pleasant (dual)touchscreen.

With the recent switch to having the hid layer handle standard axis
initialization, the Magic Trackpad now reports relative axes. This would
be fine in the normal mode, but the driver puts the device in multitouch
mode where no relative events are generated. Also, userspace software
depends on accurate axis information for device type detection. Thus,
ignoring the relative axes from the Magic Trackpad is best.

* 'fixes/2637-rc5/s3c24xx' of git://git.fluff.org/bjdooks/linux:
  ARM: S3C24XX: Fix mess with gpio {set,get}_pull callbacks
  ARM: mini2440: Fix Kconfig to allow kernel to build
  ARM: S3C2412: Fix typo in CONFIG_CPU_S3C2412_ONLY definition
  ARM: S3C2443: Select properly ARM core type
  ARM: SMDK2416: Select MACH_SMDK, S3C_DEV_NAND, S3C_DEV_USB_HOST

Currently the {set,get}_pull callbacks of the s3c24xx_gpiocfg_default structure
are initalized via s3c_gpio_{get,set}pull_1up. This results in a linker
error when only CONFIG_CPU_S3C2442 is selected:

arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f4): undefined reference to
`s3c_gpio_getpull_1up'
arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f8): undefined reference to
`s3c_gpio_setpull_1up'

The s3c2442 has pulldowns instead of pullups compared to the s3c2440.
The method of controlling them is the same though.
So this patch modifies the existing s3c_gpio_{get,set}pull_1up helper functions
to take an additional parameter deciding whether the pin has a pullup or pulldown.
The s3c_gpio_{get,set}pull_1{down,up} functions then wrap that functions passing
either S3C_GPIO_PULL_UP or S3C_GPIO_PULL_DOWN.

Furthermore this patch sets up the s3c24xx_gpiocfg_default.{get,set}_pull fields
in the s3c244{0,2}_map_io function to the new pulldown helper functions.
