From 62d5247d239d4b48762192a251c647d7c997616a Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 25 Feb 2021 18:33:18 +0200 Subject: gpiolib: acpi: Add ACPI_GPIO_QUIRK_ABSOLUTE_NUMBER quirk On some systems the ACPI tables has wrong pin number and instead of having a relative one it provides an absolute one in the global GPIO number space. Add ACPI_GPIO_QUIRK_ABSOLUTE_NUMBER quirk to cope with such cases.
