creating a DRM device that DRM Master can open and listen on for
VBlank and Page Flip events.

Qualcomm Technologies, Inc. SDE KMS HYP



Snapdragon Display Engine HYP registers with the Linux DRM/KMS framework to

facilitate DRM driver creation, publishing /dev/dri/card0, and sending

VBlank and Page Flip events to User Space listeners.



Required properties

- compatible: Must be "qcom,sde-kms-hyp"



Optional properties:

- qcom,client-id:	A four character string that is converted to a u32. It's

			understood as a hex value, if compatible (i.e. "7816").

			Otherwise, it is treated as a FourCC sequence code

			(i.e. "LV01").



Example:

	sde_kms_hyp: qcom,sde_kms_hyp@900000 {

		compatible = "qcom,sde-kms-hyp";

		qcom,client-id = "7816";

	};
