如果使用外部功放，一般需要用GPIO/GPO控制；如果只是使用内部功放，则不需控制，因为内部音频功放由ABB控制。

键盘背光控制，一般有三种硬件方案：使用GPIO/GPO控制外置ldo、基带PWL1控制和PMIC提供的KEYPAD Light接口。
使用GPIO/GPO控制ldo只能起开关作用，不能调节亮度等级，配置方式如下： .type = PMD_LEVEL_TYPE_LDO
.ldo= { .pin = { .gpoId = HAL_GPO_3}}, 使用基带上的PWL1接口时，如下配置： .type =PMD_LEVEL_TYPE_PWL1
.ldo = { .pin = { .gpoId = HAL_GPO_6}}，或任意其它值。 使用 PWL1可以调节亮度等级，分7个等级，255为最亮
.lightLevelToPwm1 = { 0, 0, 0, 0, 0, 224, 224, 224}, 使用PMIC提供的KEYPAD Light接口LED_KP，如下配置：
.type = PMD_LEVEL_TYPE_OPAL, \\ .ldo = { .opal = PMD_LDO_NONE},
LED_KP的亮度等级由.lightLevelToPwm0来控制，最大为0xFF。 .lightLevelToPwm0 = { 0, 32, 32, 32, 32, 32, 32, 32},
{ /* PMD_LEVEL_LCD : (main) LCD Back Light level*/ \\
.type = PMD_LEVEL_TYPE_BACKLIGHT, \\ .ldo = { .opal = PMD_LDO_NONE}, \\ .powerOnState = 0, \\ }, \\
LCD 背光设置和键盘背光设置相似，背光等级由.lightLevelToRda1203控制，最大0x8f88。 lightLevelToRda1203 ={ 0x8088, 0x8188, 0x8488, 0x8888, 0x8c88, 0x8d88, 0x8e88, 0x8f88} { /* PMD_LEVEL_SUB_LCD : Sub LCD Back Light level */ \\
.type = PMD_LEVEL_TYPE_NONE, \\ .ldo = { .opal = PMD_LDO_NONE}, \\ .powerOnState = 0, \\ }, \\
{ /* PMD_LEVEL_LED0 : LED0 Light level */ \\
.type = PMD_LEVEL_TYPE_NONE, \\ .ldo = { .opal = PMD_LDO_NONE}, \\ .powerOnState = 0, \\ }, \\ { /* PMD_LEVEL_LED1 : LED1 Light level */ \\
.type = PMD_LEVEL_TYPE_NONE, \\ .ldo = { .opal = PMD_LDO_NONE}, \\ .powerOnState = 0, \\ }, \\ { /* PMD_LEVEL_LED2 : LED2 Light level */ \\
.type = PMD_LEVEL_TYPE_NONE, \\ .ldo = { .opal = PMD_LDO_NONE}, \\ .powerOnState = 0, \\ }, \\ { /* PMD_LEVEL_LED3 : LED3 Light level */ \\ .type = PMD_LEVEL_TYPE_LDO, \\ .ldo = { .pin = {.gpioId = HAL_GPO_4}}, \\ .powerOnState = 0, \\ }, \\ LED3被用来作为手电筒的控制。

0x8488, 0x8488, 0x8488, 0x8488}, \\ .lightLevelToPwm0 = { 0, 32, 32, 32, 32, 32, 32, 32}, \\ .lightLevelToPwm1 = { 0, 0, 0, 0, 0, 224, 224, 224}, \\ /* Inside Gallite chip, PMD_LDO_MMC also supplies power to */ \\ /* TCU0-2, so if any of TCU0-2 is used, MMC LDO should be */ \\ /* always on in active mode and cannot be controlled as a */ \\

接设为.ldo = { .opal = PMD_LDO_NONE}, 例如这里.ldoEnableNorma是PMD_LDO_MMC，那么上面的PMD_POWER_SDMMC的.ldo就要设为PMD_LDO_NONE。 .ldoMicIs2_8 = TRUE, \\ .ldoCamIs2_8 = TRUE, \\ .ldoLcdIs2_8 = TRUE, \\ .ldoMMCIs2_8 = TRUE, \\ .ldoIbrIs2_8 = FALSE, \\ .ldoRfIs2_8 = FALSE, \\ 分别是VMIC、VCAM、VLCD、VMMC、VVIB和VRF的电压选择，TRUE为2.8V，FALSE为1.8V。gallite共有11个ldo，其它的有些由硬件配置，有些电压是固定的，所以没有在这里列出。
