Subject[PATCH 4.14 054/178] rtc: pcf8563: fix output clock rate
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Philipp Zabel <p.zabel@pengutronix.de>


[ Upstream commit a3350f9c57ffad569c40f7320b89da1f3061c5bb ]

The pcf8563_clkout_recalc_rate function erroneously ignores the
frequency index read from the CLKO register and always returns
32768 Hz.
