msm : ais : diagnostic feature 



provide the functions:
1. record the all camera related clocks' status
2. provide the get clock status interfaces
3. provide the read registers interfaces
4. provide read the regulators' status
5. provide set/get the specified gpio
6. get the ISP buffer states

[Root level node]

==================

Required properties:

- compatible: Must be "qcom,diag-cam".



[Subnode]

==========

Required properties:

- mmagic-supply: should contain mmagic regulator used for mmagic clocks.

- gdscr-supply: should contain gdsr regulator used for cci clocks.

- vfe0-vdd-supply: phandle to vfe0 regulator.

- qcom,cam-vreg-name: name of the voltage regulators required for the device.

- clocks: List of clock handles. The parent clocks of the input clocks to the

        devices in this power domain are set to oscclk before power gating

        and restored back after powering on a domain. This is required for

        all domains which are powered on and off and not required for unused

        domains.

- clock-names: name of the clock used by the driver.

- qcom,clock-rates: clock rate in Hz.

- qcom,clock-control: The valid fields are "NO_SET_RATE", "INIT_RATE" and

  "SET_RATE". "NO_SET_RATE" the corresponding clock is enabled without setting

  the rate assuming some other driver has already set it to appropriate rate.

  "INIT_RATE" clock rate is not queried assuming some other driver has set

  the clock rate and ispif will set the the clock to this rate.

  "SET_RATE" clock is enabled and the rate is set to the value specified

  in the property qcom,clock-rates.
