[PATCH v5 11/11] arm64: dts: Add PWM and SDHCI DT nodes for Stingray SOC

From: Anup Patel
Date: Fri May 26 2017 - 05:28:02 EST


From: Srinath Mannam <srinath.mannam@xxxxxxxxxxxx>

The Stingray SoC has two instances of SDHCI controller
and one instance of iProc PWM.

Let's enable above mentioned devices in Stingray DT.
