Message-Id: <1296141777-6016-1-git-send-email-ygeorgie@gmail.com> Date: Thu, 27 Jan 2011 16:22:57 +0100 From: ygeorgie <ygeorgie@...il.com> To: linux-kernel@...r.kernel.org, Richard Purdie <rpurdie@...ux.intel.com> Cc: Yury Georgievskiy <ygeorgie@...il.com> Subject: [PATCH RFC] leds: Allow heartbeat trigger to use user-defined brightness. From: Yury Georgievskiy <ygeorgie@...il.com> Led brightness for PWM leds can be dynamically adjusted. GPIO leds are not affected as only on/off states are possible. Checked with PWM leds. Writing new value in /sys/class/leds/led-pwm::/brightness alter PWM led brightness as expected.
