From: balbi@ti.com (Felipe Balbi) To: linux-arm-kernel@lists.infradead.org Subject: [PATCH] arm: dts: dra7: arch timer sits in always-on power domain Date: Mon, 13 Jul 2015 15:41:41 -0500 [thread overview] Message-ID: <1436820101-2172-1-git-send-email-balbi@ti.com> (raw) According to DRA7x TRM section 4.3.5 Realtime Counter (Master Counter), the realtime counter sits in the Wakeup Always-On Power domain. Furthermore, the counter will automatically switch the 32K clock source when MPU goes into standby and automatically switch back to SYS_CLK or ABE_LP when MPU goes out of standby.
