From 9aeb69447d3839675b2cac51c3e95a4724fd9b0d Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Fri, 5 Oct 2012 21:54:38 +0200 Subject: hpet: common ACPI generation HPET's min ticks (minimum time between events to avoid losing interrupts) is chipset specific, so move it to Kconfig. Via also has a special base address, so move it as well. Apart from these (and the base address was already #defined), the table is very uniform.
