From mboxrd@z Thu Jan 1 00:00:00 1970 From: grygorii.strashko@ti.com (Grygorii Strashko) Date: Wed, 18 Nov 2015 16:01:55 +0200 Subject: [4.4-rc][PATCH] ARM: dts: am4372: disable arm twd and global timer's nodes Message-ID: <1447855315-419-1-git-send-email-grygorii.strashko@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Keep ARM TWD and Global timer's nodes disabled by default - if someone would like to use them then those nodes have to be enabled explicitly in board file. The reason for this change is: - ARM TWD is not always-on timer on am437x and it will stop in low CPUIdle states and, therefore, broadcast timer has to configured properly if CPU_IDLE=y. - ARM Global timer is not always-on timer on am437x and it can't be used as clocksource device if CPU_IDLE=y. - ARM Global timer driver doesn't support CPUfreq now.
