From mboxrd@z Thu Jan 1 00:00:00 1970 From: daniel.lezcano@linaro.org (Daniel Lezcano) Date: Thu, 27 Jun 2013 17:30:53 +0200 Subject: [RFC PATCH] ARM: ux500: cpuidle: use of_compatible instead of cpu_id Message-ID: <1372347053-27739-1-git-send-email-daniel.lezcano@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Remove the dependency on the id.h header by replacing the cpu_is_ functions by of_machine_is_compatible. In order to have cpuidle working on these SoC, the device tree must be enabled.
