Date: Mon, 11 May 2009 22:57:03 +0000 From: Arnd Bergmann <arnd@...db.de> To: linux-kernel@...r.kernel.org, Ralf Baechle <ralf@...ux-mips.org> Subject: [PATCH] mips: use PIT_TICK_RATE in i8253 Using PIT_TICK_RATE instead of CLOCK_TICK_RATE allows us to later change CLOCK_TICK_RATE to a more sensible time base value for platforms that do not base their system timer off an i8253.
