Subject: [PATCH v5 3/3] x86/platform/intel-mid: Add special handling of ACPI HW reduced platforms
Date: Tue, 20 Feb 2018 20:05:06 +0200 [thread overview]
Message-ID: <20180220180506.65523-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20180220180506.65523-1-andriy.shevchenko@linux.intel.com>
When switching to ACPI HW reduced platforms we still want to initialize timers.
Override x86_init.acpi.reduced_hw_init to achieve that.
