If we are going to complain about coding style... this should really be split, one change per patch. > > @@ -161,18 +167,18 @@ struct lm3532_data { > > }; > > > > static const struct reg_default lm3532_reg_defs[] = { > > - {LM3532_REG_OUTPUT_CFG, 0xe4}, > > + {LM3532_REG_OUTPUT_CFG, 0x24}, > > {LM3532_REG_STARTSHUT_RAMP, 0xc0}, > > {LM3532_REG_RT_RAMP, 0xc0}, > > {LM3532_REG_PWM_A_CFG, 0x82}, > > {LM3532_REG_PWM_B_CFG, 0x82}, > > {LM3532_REG_PWM_C_CFG, 0x82}, > > {LM3532_REG_ZONE_CFG_A, 0xf1}, > > - {LM3532_REG_CTRL_A_BRT, 0xf3}, > > + {LM3532_REG_CTRL_A_FS_CURR, 0x13}, > > {LM3532_REG_ZONE_CFG_B, 0xf1}, > > - {LM3532_REG_CTRL_B_BRT, 0xf3}, > > + {LM3532_REG_CTRL_B_FS_CURR, 0x13}, > > {LM3532_REG_ZONE_CFG_C, 0xf1}, > > - {LM3532_REG_CTRL_C_BRT, 0xf3}, > > + {LM3532_REG_CTRL_C_FS_CURR, 0x13}, > > {LM3532_REG_ENABLE, 0xf8}, > > {LM3532_ALS_CONFIG, 0x44}, > > {LM3532_REG_ZN_0_HI, 0x35}, Default register values; are they related to the rest? > > @@ -302,7 +308,7 @@ static int lm3532_led_disable(struct lm3532_led *led_data) > > int ret; > > > > ret = regmap_update_bits(led_data->priv->regmap, LM3532_REG_ENABLE, > > - ctrl_en_val, ~ctrl_en_val); > > + ctrl_en_val, 0); > > if (ret) { > > dev_err(led_data->priv->dev, "Failed to set ctrl:%d\n", ret); > > return ret; This should have no functional impact, its just a clenaup, probably should go separately. > > @@ -339,11 +345,9 @@ static int lm3532_brightness_set(struct led_classdev *led_cdev, > > if (ret) > > goto unlock; > > > > - brightness_reg = LM3532_REG_CTRL_A_BRT + led->control_bank * 2; > > - brt_val = brt_val / LM3532_BRT_VAL_ADJUST; > > - > > + brightness_reg = LM3532_REG_ZONE_TRGT_A + led->control_bank * 5 + > > + (led->ctrl_brt_pointer >> 2); > > ret = regmap_write(led->priv->regmap, brightness_reg, brt_val); > > - > > unlock: > > mutex_unlock(&led->priv->lock); > > return ret; This is the core change, AFAICT. > > @@ -356,8 +360,29 @@ static int lm3532_init_registers(struct lm3532_led *led) > > unsigned int output_cfg_val = 0; > > unsigned int output_cfg_shift = 0; > > unsigned int output_cfg_mask = 0; > > + int brightness_config_reg; > > + int brightness_config_val; > > int ret, i; > > > > + if (drvdata->enable_gpio) > > + gpiod_direction_output(drvdata->enable_gpio, 1); > > + > > + brightness_config_reg = LM3532_REG_ZONE_CFG_A + led->control_bank * 2; > > + /* This could be hard coded to the default value but the control > Code is moved, probably should go in separately.
