Subject: ARM: dts: alt: Enable SCIF_CLK frequency and pins
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8a758a9493d8cac4afde82918590a11bbb24c85c;p=linux-beck.git

ARM: dts: alt: Enable SCIF_CLK frequency and pins

Add and enable the external crystal for the SCIF_CLK and its pinctrl, to
be used by the Baud Rate Generator for External Clock (BRG) on (H)SCIF.

This increases the range and accuracy of supported baud rates.
