Commit0ed266d7ae("clk: ti: omap3: cleanup unnecessary clock aliases") removed old omap3 clock framework aliases but caused omap3-rom-rng to stop working with clock not found error. Based on discussions on the mailing list it was requested by Tero Kristo that it would be best to fix this issue by probing omap3-rom-rng using device tree to provide a proper clk property. The other option would be to add back the missing clock alias, but that does not help moving things forward with removing old legacy platform_data. Let's also add a proper device tree binding and keep it together with the fix.

OMAP ROM RNG driver binding
|
|
|
|
Secure SoCs may provide RNG via secure ROM calls like Nokia N900 does. The
|
|
implementation can depend on the SoC secure ROM used.
|
|
|
|
- compatible:
|
|
Usage: required
|
|
Value type: <string>
|
|
Definition: must be "nokia,n900-rom-rng"
|
|
|
|
- clocks:
|
|
Usage: required
|
|
Value type: <prop-encoded-array>
|
|
Definition: reference to the the RNG interface clock
|
|
|
|
- clock-names:
|
|
Usage: required
|
|
Value type: <stringlist>
|
|
Definition: must be "ick"
|
|
|
|
Example:
|
|
|
|
rom_rng: rng {
|
|
compatible = "nokia,n900-rom-rng";
|
|
clocks = <&rng_ick>;
|
|
clock-names = "ick";
|
|
};
