Message-Id: <1395081521-16568-1-git-send-email-alexandre.belloni@free-electrons.com> Date: Mon, 17 Mar 2014 19:38:41 +0100 From: Alexandre Belloni <alexandre.belloni@...e-electrons.com> To: Bryan Wu <cooloney@...il.com> Cc: Richard Purdie <rpurdie@...ys.net>, linux-leds@...r.kernel.org, linux-kernel@...r.kernel.org, Alexandre Belloni <alexandre.belloni@...e-electrons.com> Subject: [PATCH] leds: pwm: set polarity on non DT platforms Set inversed polarity when .active_low is set in the platform_data. With device tree, this is taken care of by of_pwm_xlate_with_flags(), called from of_pwm_get().
