From: Simon Glass Date: Wed, 8 Jul 2020 03:32:21 +0000 (-0600) Subject: x86: pinctrl: Add multi-ACPI control X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=a9331a3388badf8a4f203d54c238f4e6bc76f247;p=u-boot.git x86: pinctrl: Add multi-ACPI control Add a Kconfig to control whether pinctrl is represented as a single ACPI device or as multiple devices. In the latter case (the default) we should return the pin number relative to the pinctrl device.
