From 32abb4788d3fff69fa242c7850e39ec1418df4f4 Mon Sep 17 00:00:00 2001 From: "G.Shark Jeong" Date: Fri, 22 Jun 2012 08:12:06 +0800 Subject: leds: Add LED driver for lm3556 chip LM3556 : The LM3556 is a 4 MHz fixed-frequency synchronous boost converter plus 1.5A constant current driver for a high-current white LED. Datasheet: www.national.com/ds/LM/LM3556.pdf Tested on OMAP4430 (bryan.wu@canonical.com: use module_i2c_driver() rather than lm3556_init/lm3556_exit for code simplicity; fixed some typo pointed out by Rob Landley) Signed-off-by: G.Shark Jeong Reviewed-by: Axel Lin Reviewed-by: Kim, Milo Acked-by: Rob Landley Signed-off-by: Bryan Wu --- include/linux/platform_data/leds-lm3556.h | 50 +++++++++++++++++++++++++++++++ 1 file changed, 50 insertions(+) create mode 100644 include/linux/platform_data/leds-lm3556.h (limited to 'include/linux') diff --git a/include/linux/platform_data/leds-lm3556.h b/include/linux/platform_data/leds-lm3556.h new file mode 100644 index 0000000..4b4e7d6 --- /dev/null +++ b/include/linux/platform_data/leds-lm3556.h @@ -0,0 +1,50 @@ +/* + * Simple driver for Texas Instruments LM3556 LED Flash driver chip (Rev0x03) + * Copyright (C) 2012 Texas Instruments + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + * + */ + +#ifndef __LINUX_LM3556_H +#define __LINUX_LM3556_H + +#define LM3556_NAME "leds-lm3556" + +enum lm3556_pin_polarity { + PIN_LOW_ACTIVE = 0, + PIN_HIGH_ACTIVE, +}; + +enum lm3556_pin_enable { + PIN_DISABLED = 0, + PIN_ENABLED, +}; + +enum lm3556_strobe_usuage { + STROBE_EDGE_DETECT = 0, + STROBE_LEVEL_DETECT, +}; + +enum lm3556_indic_mode { + INDIC_MODE_INTERNAL = 0, + INDIC_MODE_EXTERNAL, +}; + +struct lm3556_platform_data { + enum lm3556_pin_enable torch_pin_en; + enum lm3556_pin_polarity torch_pin_polarity; + + enum lm3556_strobe_usuage strobe_usuage; + enum lm3556_pin_enable strobe_pin_en; + enum lm3556_pin_polarity strobe_pin_polarity; + + enum lm3556_pin_enable tx_pin_en; + enum lm3556_pin_polarity tx_pin_polarity; + + enum lm3556_indic_mode indicator_mode; +}; + +#endif /* __LINUX_LM3556_H */ -- cgit v1.1
