From ebeec0af5b29635b847f5a7a17de1900193d0257 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 18 Jul 2013 00:54:23 +0200 Subject: pwm: Update DT bindings to reference pwm.txt for cells documentation The PWM client cells format is documented in the generic pwm.txt documentation and duplicated in all PWM driver bindings. Remove duplicate information and reference pwm.txt instead.
