Qualcomm Technologies, Inc Shared Memory Packet Driver (smdpkt)

[Root level node]

Required properties:

-compatible : should be "qcom,smdpkt"

[Second level nodes]

qcom,smdpkt-port-names

Required properties:

-qcom,smdpkt-remote : the remote subsystem name

-qcom,smdpkt-port-name : the smd channel name

-qcom,smdpkt-dev-name : the smdpkt device name

Example:

	qcom,smdpkt {

		compatible = "qcom,smdpkt";

		qcom,smdpkt-data5-cntl {

			qcom,smdpkt-remote = "modem";

			qcom,smdpkt-port-name = "DATA5_CNTL";

			qcom,smdpkt-dev-name = "smdcntl0";

		};

		qcom,smdpkt-data6-cntl {

			qcom,smdpkt-remote = "modem";

			qcom,smdpkt-port-name = "DATA6_CNTL";

			qcom,smdpkt-dev-name = "smdcntl1";

		};

Qualcomm Technologies, Inc Shared Memory TTY Driver (smdtty)

[Root level node]

Required properties:

-compatible : should be "qcom,smdtty"

[Second level nodes]

qcom,smdtty-port-names

Required properties:

-qcom,smdtty-remote: the remote subsystem name

-qcom,smdtty-port-name : the smd channel name

Optional properties:

-qcom,smdtty-dev-name : the smdtty device name

Required alias:

- The index into TTY subsystem is specified via an alias with the following format

         'smd{n}' where n is the tty device index.

Example:

	aliases {

		smd1 = &smdtty_apps_fm;

		smd36 = &smdtty_loopback;

	};

	qcom,smdtty {

		compatible = "qcom,smdtty";

		smdtty_apps_fm: qcom,smdtty-apps-fm {

			qcom,smdtty-remote = "wcnss";

			qcom,smdtty-port-name = "APPS_FM";

		};

		smdtty_loopback: smdtty-loopback {

			qcom,smdtty-remote = "modem";

			qcom,smdtty-port-name = "LOOPBACK";

			qcom,smdtty-dev-name = "LOOPBACK_TTY";

		};

	};

			This should be in decidegree and if not specified

			default select value is 10 DeciDegC.

			<RISE_HYS_DECIDEG_C, FALL_HYS_DECIDEG_C>

- qcom,jeita-fcc-scaling: A bool property to indicate if temperature based

			jeita fcc scaling is enabled. If defined, enables

			scaling of FCC based on battery-temperature. Scales

			the FCC depending upon the granularity of increase in

			battery temperature.

- qcom,jeita-fcc-scaling-temp-threshold: A tuple entry to allow configuring the

			min and max battery temperature threshold (in DeciDegC)

			for jeita fcc scaling algorithm to kick in.

			<MIN_BATT_TEMP_DECIDEG_C, MAX_BATT_TEMP_DECIDEG_C>

- qcom,jeita-scaling-min-fcc-ua : This value corresponds to the minimum FCC (in uA) of

			the battery to be applied when battery temperature hits the max

			temperature indicated it "qcom,jeita-fcc-scaling-temp-threshold".

			This value is selected based on profiling after making sure that

			the battery-temperature does not rise at this FCC.

Profile data node required subnodes:

- qcom,fcc-temp-lut : An 1-dimensional lookup table node that encodes

			temperature to fcc lookup. The units for this lookup

Qti radio iris device

-FM RX playback with no RDS

   FM samples is filtered by external RF chips at baseband, then send to Riva-FM core through serial link.

   FM signal is demodulated then audio L/R samples are stored inside memory.

   FM Rx received samples data is connected to external audio codec.

-Audio playback to FM TX

  Used to play audio source  to FM TX.

  FM TX module will read the audio samples from memory then modulated samples will be send through serial interface to external RF chip.

-RX playback with RDS

  FM Rx receive audio data along with RDS.

-FM TX with RDS

  Used to send RDS messages to external FM receiver.

Required Properties:

- compatible: "qcom,iris_fm"

Example:

        qcom,iris-fm {

                compatible = "qcom,iris_fm";

        };
