From a39a6405d5f949bc651694028a55d74c514ef1f9 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Fri, 16 Oct 2015 13:31:29 +0200 Subject: rtc: pcf8563: add CLKOUT to common clock framework Add the clkout output clk to the common clock framework. Disable the CLKOUT of the RTC after power-up. After power-up/reset of the RTC, CLKOUT is enabled by default, with CLKOUT enabled the RTC chip has 2-3 times higher power consumption.
