2020-05-25drivers: Use SPDX identifiersJacob Garber
Convert the remaining files in src/drivers to use SPDX identifiers. int15.h and default_brightness_levels.asl did not have license headers, but they were both copied from other GPL2 files, so they should be under the GPL2 as well. ne2k.c and drm_dp_helper.h are licensed under custom BSD-like licenses that do not have an SPDX equivalent, so they are added as exceptions to the license header lint.

2020-03-31drivers/intel/gma: fold gma.asl into default_brightness_levels.aslMatt DeVillier
Including gma.asl at the platform level (vs the board level) means that even desktop boards need to include the default brightness levels, which makes no sense. To begin to clean this up, include gma.asl in default_brightness_levels.asl (as well as the handful of board-specific brightness files) and remove it from the various platforms. A follow-on commit will remove default_brightness_levels.asl from all boards which lack an internal display.

2020-03-24drivers/intel/gma/acpi: Reduce display switching stubsNico Huber
_DCS, _DGS and _DSS are required by specification. However, we never implemented them properly, and no OS driver com- plained yet. So we stub them out and keep the traditional behavior in case an OS driver checks for their existence. The old implementations also only returned static values as there never was any write to their GNVS variables. The TRAP() that was called in one place is actually implemented by some ThinkPad's SMI handler as docking event. However, as the call precedes these SMI handlers in coreboot history, it's most likely an accident.

2020-03-11drivers/intel/gma/acpi: Prevent DivideByZero errorPatrick Rudolph
In case backlight control isn't enabled BCLM is zero. Return early instead of running into a DivideByZero error. This happens on devices that don't have backlight control, like desktops and servers. The proper fix is to not include those ACPI methods, but that requires a much bigger refactoring.

2018-09-14drivers/intel/gma: Do not rely on CBLV in OpRegion Mailbox3Nico Huber
CBLV is not kept up to date by Linux' i915. We should fix that too, but it will likely take some years until we can always expect it to work. For now read the register values directly. To accomodate that we are not the only one writing those, revise XBQC() to search for the closest value in BRIG (instead of a lower equal one) and round more accurately for better matches.

2018-08-30drivers/intel/gma: store uint8_t brightness values in mailbox3Alexander Couzens
The _BCM function requires a percentage value. While the brightness in mailbox3 requires a value in uint8_t. Meaning 255 = 100%. Previous implementation stored the percentage brightness value resulting in limiting the brightness to ~40% of it's maximum power. Only affects brightness control using mailbox3.

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.
