Top Control and Status Register(TCSR) for HGSL



TCSR hardware contains compute signal sub-block, which allows drivers in hypervisor

Linux to communicate with GPU hardware directly. This HGSL TCSR driver is to enable

the TCSR compute signal hardware. There are multiple instances of compute signal.

Each instance is either a signal sender or signal receiver.



The HGSL TCSR driver is built on top of generic TCSR driver, refer to

Documentation/devicetree/bindings/mfd/qcom,tcsr.txt for the generic TCSR driver.



Required properties:

- compatible : Must be "qcom,hgsl-tcsr-sender" or "qcom,hgsl-tcsr-receiver"

- syscon     : Point to the generic TCSR compute signal node

- syscon-glb : Point to the generice TCSR node for compute signal global control.

	       This is only needed by signal sender.

- interrupts : Specify IRQ information used by the compute signal.

	       This is only needed by signal receiver.



Examples:

	hgsl_tcsr_sender0: hgsl_tcsr_sender0 {

		compatible = "qcom,hgsl-tcsr-sender";

		syscon = <&tcsr_compute_signal_sender0>;

		syscon-glb = <&tcsr_compute_signal_glb>;

	};



	hgsl_tcsr_receiver0: hgsl_tcsr_receiver0 {

		compatible = "qcom,hgsl-tcsr-receiver";

		syscon = <&tcsr_compute_signal_receiver0>;

		interrupts = <0 238 0>;

	};

* HGSL



HGSL(Hypervisor Graphics system layer) is graphics driver under the hypervisor system.



Required properties:

- compatible : Must be "qcom,hgsl"



- reg : physical base address and length of the register set(s).



- reg-names : names corresponding to each reg property value.

	      reg_hwver: HW version registers

	      reg_doorbell_idx: address of GMUAO_DOORBELL_IDX



Optional properties:

- qcom,glb-db-senders : Point to possible nodes of HGSL TCSR sender. The user will select

		        which sender to use. The driver will use TCSR compute signal to

		        send signal to GPU.

- qcom,glb-db-receivers : Point to possible nodes of HGSL TCSR receiver. The user will

			  select which receiver to use. The driver will use TCSR compute

			  signal to receive signal from GPU.



Example:

	msm_gpu_hyp {

		compatible = "qcom,hgsl";

		reg = <0x2c00000 0x8>, <0x2c8f000 0x4>;

		reg-names = "hgsl_reg_hwinf", "hgsl_reg_gmucx";



		qcom,glb-db-senders = <&hgsl_tcsr_sender0 &hgsl_tcsr_sender1>;

		qcom,glb-db-receivers = <&hgsl_tcsr_receiver0 &hgsl_tcsr_receiver1>;

	};
