From 28e64a68a2ef1c48f30e8b6803725199929069fc Mon Sep 17 00:00:00 2001 From: Daniel Jeong Date: Tue, 12 Nov 2013 15:08:58 -0800 Subject: backlight: lm3630: apply chip revision The LM3630 chip was revised by TI and chip name was also changed to LM3630A. And register map, default values and initial sequences are changed. The files, lm3630_bl.{c,h} are replaced by lm3630a_bl.{c,h} You can find more information about LM3630A(datasheet, evm etc) at http://www.ti.com/product/lm3630a Signed-off-by: Daniel Jeong Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/linux/platform_data/lm3630_bl.h | 57 ---------------------------- include/linux/platform_data/lm3630a_bl.h | 65 ++++++++++++++++++++++++++++++++ 2 files changed, 65 insertions(+), 57 deletions(-) delete mode 100644 include/linux/platform_data/lm3630_bl.h create mode 100644 include/linux/platform_data/lm3630a_bl.h (limited to 'include') diff --git a/include/linux/platform_data/lm3630_bl.h b/include/linux/platform_data/lm3630_bl.h deleted file mode 100644 index 9176dd3f2d63..000000000000 --- a/include/linux/platform_data/lm3630_bl.h +++ /dev/null @@ -1,57 +0,0 @@ -/* -* Simple driver for Texas Instruments LM3630 LED Flash driver chip -* 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_LM3630_H -#define __LINUX_LM3630_H - -#define LM3630_NAME "lm3630_bl" - -enum lm3630_pwm_ctrl { - PWM_CTRL_DISABLE = 0, - PWM_CTRL_BANK_A, - PWM_CTRL_BANK_B, - PWM_CTRL_BANK_ALL, -}; - -enum lm3630_pwm_active { - PWM_ACTIVE_HIGH = 0, - PWM_ACTIVE_LOW, -}; - -enum lm3630_bank_a_ctrl { - BANK_A_CTRL_DISABLE = 0x0, - BANK_A_CTRL_LED1 = 0x4, - BANK_A_CTRL_LED2 = 0x1, - BANK_A_CTRL_ALL = 0x5, -}; - -enum lm3630_bank_b_ctrl { - BANK_B_CTRL_DISABLE = 0, - BANK_B_CTRL_LED2, -}; - -struct lm3630_platform_data { - - /* maximum brightness */ - int max_brt_led1; - int max_brt_led2; - - /* initial on brightness */ - int init_brt_led1; - int init_brt_led2; - enum lm3630_pwm_ctrl pwm_ctrl; - enum lm3630_pwm_active pwm_active; - enum lm3630_bank_a_ctrl bank_a_ctrl; - enum lm3630_bank_b_ctrl bank_b_ctrl; - unsigned int pwm_period; - void (*pwm_set_intensity) (int brightness, int max_brightness); -}; - -#endif /* __LINUX_LM3630_H */ diff --git a/include/linux/platform_data/lm3630a_bl.h b/include/linux/platform_data/lm3630a_bl.h new file mode 100644 index 000000000000..7538e38e270b --- /dev/null +++ b/include/linux/platform_data/lm3630a_bl.h @@ -0,0 +1,65 @@ +/* +* Simple driver for Texas Instruments LM3630A LED Flash driver chip +* 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_LM3630A_H +#define __LINUX_LM3630A_H + +#define LM3630A_NAME "lm3630a_bl" + +enum lm3630a_pwm_ctrl { + LM3630A_PWM_DISABLE = 0x00, + LM3630A_PWM_BANK_A, + LM3630A_PWM_BANK_B, + LM3630A_PWM_BANK_ALL, + LM3630A_PWM_BANK_A_ACT_LOW = 0x05, + LM3630A_PWM_BANK_B_ACT_LOW, + LM3630A_PWM_BANK_ALL_ACT_LOW, +}; + +enum lm3630a_leda_ctrl { + LM3630A_LEDA_DISABLE = 0x00, + LM3630A_LEDA_ENABLE = 0x04, + LM3630A_LEDA_ENABLE_LINEAR = 0x14, +}; + +enum lm3630a_ledb_ctrl { + LM3630A_LEDB_DISABLE = 0x00, + LM3630A_LEDB_ON_A = 0x01, + LM3630A_LEDB_ENABLE = 0x02, + LM3630A_LEDB_ENABLE_LINEAR = 0x0A, +}; + +#define LM3630A_MAX_BRIGHTNESS 255 +/* + *@leda_init_brt : led a init brightness. 4~255 + *@leda_max_brt : led a max brightness. 4~255 + *@leda_ctrl : led a disable, enable linear, enable exponential + *@ledb_init_brt : led b init brightness. 4~255 + *@ledb_max_brt : led b max brightness. 4~255 + *@ledb_ctrl : led b disable, enable linear, enable exponential + *@pwm_period : pwm period + *@pwm_ctrl : pwm disable, bank a or b, active high or low + */ +struct lm3630a_platform_data { + + /* led a config. */ + int leda_init_brt; + int leda_max_brt; + enum lm3630a_leda_ctrl leda_ctrl; + /* led b config. */ + int ledb_init_brt; + int ledb_max_brt; + enum lm3630a_ledb_ctrl ledb_ctrl; + /* pwm config. */ + unsigned int pwm_period; + enum lm3630a_pwm_ctrl pwm_ctrl; +}; + +#endif /* __LINUX_LM3630A_H */ -- cgit v1.2.3
