| * struct pm8xxx_mpp_config_data - structure to specify mpp configuration values |
| * @type: MPP type which determines the overall MPP function (i.e. digital |
| * in/out/bi, analog in/out, current sink, or test). It should be |
| * set to the value of one of PM8XXX_MPP_TYPE_D_*. |
| * @level: meaning depends upon MPP type specified |
| * @control: meaning depends upon MPP type specified |
| * |
| * Usage of level argument: |
| * 1. type = PM8XXX_MPP_TYPE_D_INPUT, PM8XXX_MPP_TYPE_D_OUTPUT, |
| * PM8XXX_MPP_TYPE_D_BI_DIR, or PM8XXX_MPP_TYPE_DTEST_OUTPUT - |
| * |
| * level specifies that digital logic level to use for the MPP. It should |
| * be set to the value of one of PM8XXX_MPP_DIG_LEVEL_*. Actual regulator |
| * connections for these level choices are PMIC chip specific. |
| * |
| * 2. type = PM8XXX_MPP_TYPE_A_INPUT - |
| * |
| * level specifies where in the PMIC chip the analog input value should |
| * be routed to. It should be set to the value of one of |
| * PM8XXX_MPP_AIN_AMUX_*. |
| * |
| * 3. type = PM8XXX_MPP_TYPE_A_OUTPUT - |
| * |
| * level specifies the output analog voltage reference level. It should |
| * be set to the value of one of PM8XXX_MPP_AOUT_LVL_*. |
| * |
| * 4. type = PM8XXX_MPP_TYPE_SINK or PM8XXX_MPP_TYPE_DTEST_SINK - |
| * |
| * level specifies the output current level. It should be set to the value |
| * of one of PM8XXX_MPP_CS_OUT_*. |
| * |
| * Usage of control argument: |
| * 1. type = PM8XXX_MPP_TYPE_D_INPUT - |
| * |
| * control specifies how the digital input should be routed in the chip. |
| * It should be set to the value of one of PM8XXX_MPP_DIN_TO_*. |
| * |
| * 2. type = PM8XXX_MPP_TYPE_D_OUTPUT - |
| * |
| * control specifies the digital output value. It should be set to the |
| * value of one of PM8XXX_MPP_DOUT_CTRL_*. |
| * |
| * 3. type = PM8XXX_MPP_TYPE_D_BI_DIR - |
| * |
| * control specifies the pullup resistor value. It should be set to the |
| * value of one of PM8XXX_MPP_BI_PULLUP_*. |
| * |
| * 4. type = PM8XXX_MPP_TYPE_A_INPUT - |
| * |
| * control is unused; a value of 0 is sufficient. |
| * |
| * 5. type = PM8XXX_MPP_TYPE_A_OUTPUT - |
| * |
| * control specifies if analog output is enabled. It should be set to the |
| * value of one of PM8XXX_MPP_AOUT_CTRL_*. |
| * |
| * 6. type = PM8XXX_MPP_TYPE_SINK - |
| * |
| * control specifies if current sinking is enabled. It should be set to |
| * the value of one of PM8XXX_MPP_CS_CTRL_*. |
| * |
| * 7. type = PM8XXX_MPP_TYPE_DTEST_SINK - |
| * |
| * control specifies if current sinking is enabled. It should be set to |
| * the value of one of PM8XXX_MPP_DTEST_CS_CTRL_*. |
| * |
| * 8. type = PM8XXX_MPP_TYPE_DTEST_OUTPUT - |
| * |
| * control specifies which DTEST bus value to output. It should be set to |
| * the value of one of PM8XXX_MPP_DTEST_*. |
