* Backlight control has some unfortunate properties:
* - many machines won't give us brightness change notifications
* o brightness hotkeys
* o events like AC plug/unplug (can be controlled via _DOS setting)
* o ambient light sensor triggered changes
* - some machines use the so-called "legacy" backlight interface
* o resulting brightness is a combo of LBB and PWM values
* o LBB sits in config space
* - some machines have ACPI methods for changing brightness
* o one of the few ways the X server and firmware can stay in sync
* - new machines have the IGD OpRegion interface available
* o a reliable way of keeping the firmware and X in sync
*
* So the real problem is on machines where ACPI or OpRegion methods aren't
* available. In that case, problems can occur:
* 1) the BIOS and X will have different ideas of what the brightness is,
* leading to unexpected results when the brightness is increased or
* decreased via hotkey or X protocol
* 2) unless X takes the legacy register into account, machines using it
* may prevent X from raising the brightness above 0 if the firmware
* set LBB to 0
* Given these problems, we provide the user with a selection of methods,
* so they can choose an ideal one for their platform (assuming our quirk
* code picks the wrong one).
*
* Four different backlight control methods are available:
* BCM_NATIVE: only ever touch the native backlight control registers
* This method may be susceptible to problem (2) above if the firmware
* modifies the legacy registers.
* BCM_LEGACY: only ever touch the legacy backlight control registers
* This method may be susceptible to problem (1) above if the firmware
* also modifies the legacy registers.
* BCM_COMBO: try to use both sets
* In this case, the driver will try to modify both sets of registers
* if needed. To avoid problem (2) above it may set the LBB register
* to a non-zero value if the brightness is to be increased. It's still
* susceptible to problem (1), but to a lesser extent than the LEGACY only
* method.
* BCM_KERNEL: use kernel methods for controlling the backlight
* This is only available on some platforms, but where present this can
* provide the best user experience.
