| * AB8500 Multi-Functional Device (MFD) | ||
|
|
||
| Required parent device properties: | ||
| - compatible : contains "stericsson,ab8500"; | ||
| - interrupts : contains the IRQ line for the AB8500 | ||
| - interrupt-controller : describes the AB8500 as an Interrupt Controller (has its own domain) | ||
| - #interrupt-cells : should be 2, for 2-cell format | ||
| - The first cell is the AB8500 local IRQ number | ||
| - The second cell is used to specify optional parameters | ||
| - bits[3:0] trigger type and level flags: | ||
| 1 = low-to-high edge triggered | ||
| 2 = high-to-low edge triggered | ||
| 4 = active high level-sensitive | ||
| 8 = active low level-sensitive | ||
|
|
||
| Optional parent device properties: | ||
| - reg : contains the PRCMU mailbox address for the AB8500 i2c port | ||
|
|
||
| The AB8500 consists of a large and varied group of sub-devices: | ||
|
|
||
| Device IRQ Names Supply Names Description | ||
| ------ --------- ------------ ----------- | ||
| ab8500-bm : : : Battery Manager | ||
| ab8500-btemp : : : Battery Temperature | ||

| SW_CONV_END : : | ||
| ab8500-gpio : : : GPIO Controller | ||
| ab8500-ponkey : ONKEY_DBF : : Power-on Key | ||
| ONKEY_DBR : : | ||
| ab8500-pwm : : : Pulse Width Modulator | ||
| ab8500-regulator : : : Regulators | ||
| ab8500-rtc : 60S : : Real Time Clock | ||
| : ALARM : : | ||
| ab8500-sysctrl : : : System Control | ||
| ab8500-usb : ID_WAKEUP_R : vddulpivio18 : Universal Serial Bus | ||
| : ID_WAKEUP_F : v-ape : | ||

| Required child device properties: | ||
| - compatible : "stericsson,ab8500-[bm|btemp|charger|fg|gpadc|gpio|ponkey| | ||
| pwm|regulator|rtc|sysctrl|usb]"; | ||
|
|
||
| Optional child device properties: | ||
| - interrupts : contains the device IRQ(s) using the 2-cell format (see above) | ||
| - interrupt-names : contains names of IRQ resource in the order in which they were | ||
| supplied in the interrupts property | ||
| - <supply_name>-supply : contains a phandle to the regulator supply node in Device Tree | ||
