1*4882a593SmuzhiyunNVIDIA Tegra Activity Monitor
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThe activity monitor block collects statistics about the behaviour of other
4*4882a593Smuzhiyuncomponents in the system. This information can be used to derive the rate at
5*4882a593Smuzhiyunwhich the external memory needs to be clocked in order to serve all requests
6*4882a593Smuzhiyunfrom the monitored clients.
7*4882a593Smuzhiyun
8*4882a593SmuzhiyunRequired properties:
9*4882a593Smuzhiyun- compatible: should be "nvidia,tegra<chip>-actmon"
10*4882a593Smuzhiyun- reg: offset and length of the register set for the device
11*4882a593Smuzhiyun- interrupts: standard interrupt property
12*4882a593Smuzhiyun- clocks: Must contain a phandle and clock specifier pair for each entry in
13*4882a593Smuzhiyunclock-names. See ../../clock/clock-bindings.txt for details.
14*4882a593Smuzhiyun- clock-names: Must include the following entries:
15*4882a593Smuzhiyun  - actmon
16*4882a593Smuzhiyun  - emc
17*4882a593Smuzhiyun- resets: Must contain an entry for each entry in reset-names. See
18*4882a593Smuzhiyun../../reset/reset.txt for details.
19*4882a593Smuzhiyun- reset-names: Must include the following entries:
20*4882a593Smuzhiyun  - actmon
21*4882a593Smuzhiyun
22*4882a593SmuzhiyunExample:

25*4882a593Smuzhiyun		reg = <0x0 0x6000c800 0x0 0x400>;
26*4882a593Smuzhiyun		interrupts = <GIC_SPI 45 IRQ_TYPE_LEVEL_HIGH>;
27*4882a593Smuzhiyun		clocks = <&tegra_car TEGRA124_CLK_ACTMON>,
28*4882a593Smuzhiyun			 <&tegra_car TEGRA124_CLK_EMC>;
29*4882a593Smuzhiyun		clock-names = "actmon", "emc";
30*4882a593Smuzhiyun		resets = <&tegra_car 119>;
31*4882a593Smuzhiyun		reset-names = "actmon";
