This patch the necessary documentation for the 'freq-tbl-khz' property as optional one so that probe doesn't fail in its absence and devfreq_add_device() also gets a chance to set up the freq table for simple-dev. Change-Id: I715a7cc0b2d2b92ede44b1f5a0647f2e62382556

Devfreq simple device
|
|
|
|
devfreq-simple-dev is a device that represents a simple device that cannot do
|
|
any status reporting and uses a clock that can be scaled by one of more
|
|
devfreq governors. It provides a list of usable frequencies for the device
|
|
and some additional optional parameters.
|
|
|
|
Required properties:
|
|
- compatible: Must be "devfreq-simple-dev"
|
|
- clock-names: Must be "devfreq_clk"
|
|
- clocks: Must refer to the clock that's fed to the device.
|
|
Optional properties:
|
|
- polling-ms: Polling interval for the device in milliseconds. Default: 50
|
|
- governor: Initial governor to user for the device. Default: "performance"
|
|
- qcom,prepare-clk: Prepare the device clock during initialization.
|
|
- freq-tbl-khz: A list of usable frequencies (in kHz) for the device
|
|
clock.
|
|
|
|
Example:
|
|
|
|
qcom,cache {
|
|
compatible = "devfreq-simple-dev";
|
|
clock-names = "devfreq_clk";
|
|
clocks = <&clock_krait clk_l2_clk>;
|
|
polling-ms = 50;
|
|
governor = "cpufreq";
|
|
freq-tbl-khz =
