2016-08-24drm/gma500: remove unnecessary config_enabled() guardMasahiro Yamada1-4/+1
Commit d112a8163f83 ("gma500/cdv: Add eDP support") replaced the code inside this if-conditional with gma_backlight_set(), which becomes a nop stub if CONFIG_BACKLIGHT_CLASS_DEVICE is disabled. So, there is no need to guard the caller with config_enabled(). Note: This is one of remaining TODOs to deprecate config_enabled() macro. Refer to commit 97f2645f358b ("tree-wide: replace config_enabled() with IS_ENABLED()").

2014-03-17drm/gma500: Move asle interrupt work into a work taskPatrik Jakobsson1-4/+21
Previously the backlight code was called from IRQ context which isn't allowed. This patch moves all the asle work into a work task which takes care of the locking bug reported by users.

2013-12-07ACPI / i915: Fix incorrect <acpi/acpi.h> inclusions via <linux/acpi_io.h>Lv Zheng1-1/+0
To avoid build problems and breaking dependencies between ACPI header files, <acpi/acpi.h> should not be included directly by code outside of the ACPI core subsystem. However, that is possible if <linux/acpi_io.h> is included, because that file contains a direct inclusion of <acpi/acpi.h>. For this reason, remove the direct <acpi/acpi.h> inclusion from <linux/acpi_io.h>, move that file from include/linux/ to include/acpi/ and make <linux/acpi.h> include it for CONFIG_ACPI set along with the other ACPI header files. Accordingly, Remove the inclusions of <linux/acpi_io.h> from everywhere. Of course, that causes the contents of the new <acpi/acpi_io.h> file to be available for CONFIG_ACPI set only, so intel_opregion.o that depends on it should also depend on CONFIG_ACPI (and it really should not be compiled for CONFIG_ACPI unset anyway).

2012-08-24gma500/cdv: Add eDP supportZhao Yakui1-2/+1
Introduce the eDP support into the driver. This has been reworked a bit because kernel driver proper uses encoder/connectors while the legacy Intel driver uses the old output stuff. It also diverges on the backlight handling. The legacy Intel driver adds a panel abstraction based upon the i915 one. It's only really used for backlight bits and we have a perfectly good backlight abstraction which can extend instead.

2012-07-16gma500: move the ASLE enableAlan Cox1-5/+3
Otherwise we end up getting the masks wrong, can get events before we are doing power control and other ungood things. Again this is a regression fix where the ordering of handling was disturbed by other work, and the user experience on some boxes is a blank screen.

2012-05-07gma500: opregion and ACPIAlan Cox1-0/+350
Add the opregion support and bring us in line with the opregion functionality in the reference driver code. We can't share this with i915 currently because there are hardcoded assumptions about dev_priv etc in both versions.
