[Patch v4 4/6] ARM: OMAP2+: DRA7: Add hwmod entries for PWMSS

From: Franklin S Cooper Jr <hidden>
Date: 2016-03-07 20:41:08
Also in: linux-devicetree, linux-omap, linux-pwm, lkml
Subsystem: arm port, omap hwmod data, omap2+ support, the rest · Maintainers: Russell King, Paul Walmsley, Aaro Koskinen, Andreas Kemnade, Kevin Hilman, Roger Quadros, Tony Lindgren, Linus Torvalds

From: Vignesh R <vigneshr@ti.com>

Add hwmod entries for the PWMSS on DRA7.

Set l4_root_clk_div as the main_clk of PWMSS. It is fixed-factored clock
equal to L4PER2_L3_GICLK/2(l3_iclk_div/2).
