From 586b1beb9c11165265310883bfca209a0356c0ab Mon Sep 17 00:00:00 2001 From: Michael Niewöhner Date: Mon, 27 Sep 2021 23:08:59 +0200 Subject: soc/intel: drop Kconfig `PM_ACPI_TIMER_OPTIONAL` MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Technically, it's not depending on the hardware but on the software (OS/payload), if the PM Timer is optional. OSes with ACPI >= 5.0A support disabling of the PM Timer, when the respective FADT flag is unset. Thus, drop this guard. For platforms without hardware PM Timer (Apollo Lake, Gemini Lake) the Kconfig `USE_PM_ACPI_TIMER` depends on `!NO_PM_ACPI_TIMER`. As of this change, new platforms must either implement code for disabling the hardware PM timer or select `NO_PM_ACPI_TIMER` if no such is present.
