backlight: gpio_backlight: Delete pdata inversion

2017-08-07T16:11:28+00:00

The option to invert the output of the GPIO (active low) is not used by the only platform still using platform data to set up a GPIO backlight (one SH board). Delete the option as we do not expect to expand the use of board files for this driver, and GPIO descriptors intrinsically keep track of any signal inversion.

treewide: Consolidate Apple DMI checks

2017-08-03T21:26:22+00:00

We're about to amend ACPI bus scan with DMI checks whether we're running on a Mac to support Apple device properties in AML. The DMI checks are performed for every single device, adding overhead for everything x86 that isn't Apple, which is the majority. Rafael and Andy therefore request to perform the DMI match only once and cache the result. Outside of ACPI various other Apple DMI checks exist and it seems reasonable to use the cached value there as well. Rafael, Andy and Darren suggest performing the DMI check in arch code and making it available with a header in include/linux/platform_data/x86/. To this end, add early_platform_quirks() to arch/x86/kernel/quirks.c to perform the DMI check and invoke it from setup_arch(). Switch over all existing Apple DMI checks, thereby fixing two deficiencies: * They are now #defined to false on non-x86 arches and can thus be optimized away if they're located in cross-arch code. * Some of them only match "Apple Inc." but not "Apple Computer, Inc.", which is used by BIOSes released between January 2006 (when the first x86 Macs started shipping) and January 2007 (when the company name changed upon introduction of the iPhone).
