2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2015-10-22gma ACPI: Make brightness levels a per board settingNico Huber
Those are actually board specific. Keep the old value as defaults, though. The defaults are included by all affected boards.

2015-10-12gma ACPI: Do not overwrite backlight configurationNico Huber
Changes to CR1 and CR2 were effectively overwriting the backlight configuration from the devicetree with static values. Instead read the maximum brightness value from BCLM (backlight modulation frequency) and calculate the target level (Arg0 is the target level as percentage). Turned out that _BQC has to return a value from the list returned by _BCL. So XBQC got a little heavier to search for the correct value.

2015-10-12gma ACPI: Consolidate non-PCH and PCH brightness levelsNico Huber
The two cases only differ in the register locations. As the values in BRIG were all the same, consolidate them. They also got normalized to percentages as the ACPI spec wants that (0x61 was 100% before).

2015-10-12gma: Consolidate Intel IGD ACPI code some moreNico Huber
Consolidate some common (and mostly broken) code. Will try to fix things in separate commits. Maybe, igd.asl taken from gm45 (the non-PCH case) could also be used for i945 and sch. But this needs further investigation.
