- reg : offset and length of the register set for the device.

    for the flash operating in compatible mode.

- gpios : should contain phandle to gpio controller node and array of

    #gpio-cells specifying specific gpio (controller specific)

- qcom,gpio-req-tbl-num : should contain index to gpios specific to this flash

- qcom,gpio-req-tbl-flags : should contain direction of gpios present in

    qcom,gpio-req-tbl-num property (in the same order)

- qcom,gpio-req-tbl-label : should contain name of gpios present in

    qcom,gpio-req-tbl-num property (in the same order)

- qcom,gpio-flash-reset : should contain index to gpio used by flash's "flash reset" pin.

- qcom,gpio-flash-en : should contain index to gpio used by flash's "flash enable" pin.

- qcom,gpio-flash-now : should contain index to gpio used by flash's "flash now" pin.

- label : should contain unique flash name to differentiate from other flash

    - "adp1660"

    - "bd7710"

- qcom,flash-type : Should contain type flash device

    - 1 for LED flash

    - 2 for strobe flash

      This is a low cost led used for camera flash, the led is driven by

      system power, and use a transistor controlled by external pin to

      gate its on/off state.

- qcom,cci-master : should contain i2c master id to be used for this flash.

    - 0 -> MASTER 0

    - 1 -> MASTER 1

- qcom,flash-source : Should contain array of phandles to flash source nodes.

    - pm8941_flash0 pm8941_flash1

- qcom,max-duration: Max duration in milliseconds the flash can glow.

-qcom,switch-source : Should contain phandle to switch source node.

      This is used to trigger dual led at same time to avoid sync issues.

- qcom,cci-master : should contain i2c master id to be used for this flash.

    - 0 -> MASTER 0

    - 1 -> MASTER 1

- reg : offset and length of the register set for the device.

    for the flash operating in compatible mode.
