* avtimer
|
|
|
|
Avtimer provides an interface for clients to enable avtimer block
|
|
on qdsp6. 64 bit AVtimer exposed by qdsp6 is used for audio and video
|
|
stream synchronization during capture and playback usecases.
|
|
|
|
Required properties:
|
|
- reg : physical address and length of avtimer register
|
|
- reg-names : AVtimer register name
|
|
Required register resource entries are:
|
|
"avtimer_lsb_addr" : AVtimer lsb physical address
|
|
"avtimer_msb_addr" : AVtimer msb physical address
|
|
- compatible : Must be "qcom,avtimer"
|
|
|
|
Optional properties:
|
|
- clk-div : The clk is at 27MHz and hence ticks are to be
|
|
divided by 27 to achive the msec value.
|
|
|
|
Example:
|
|
qcom,avtimer@90f7000 {
|
|
compatible = "qcom,avtimer";
|
|
reg = <0x90f700c 0x4>,
|
|
<0x90f7010 0x4>;
|
|
reg-names = "avtimer_lsb_addr", "avtimer_msb_addr";
|
|
qcom,clk-div = <27>;
|
|
};
