+* Low Power Management Levels
+
+The application processor in MSM can do a variety of C-States for low power
+management. These C-States are invoked by the CPUIdle framework when the core
+becomes idle. But based on the time available until the next scheduled wakeup,
+the system can do a combination of low power modes of different resources -
+L2, XO, Vdd Dig and Vdd Mem. The combination is captured in the device tree as
+lpm-level. The units for voltage are dependent on the PMIC used on the target
+and are in uV.
+
+The required nodes for lpm-levels are:
+
+- compatible: "qcom,lpm-levels"
+- reg: The numeric level id
+- qcom,mode: The sleep mode of the processor
+- qcom,xo: The state of XO clock.
+- qcom,l2: The state of L2 cache.
+- qcom,vdd-mem-upper-bound: The upper bound value of mem voltage in uV
+- qcom,vdd-mem-lower-bound: The lower bound value of mem voltage in uV
+- qcom,vdd-dig-upper-bound: The upper bound value of dig voltage in uV
+- qcom,vdd-dig-lower-bound: The lower bound value of dig voltage in uV
+- qcom,latency-us: The latency in handling the interrupt if this level was
+	chosen, in uSec
+- qcom,ss-power: The steady state power expelled when the processor is in this
+	level in mWatts
+- qcom,energy-overhead: The energy used up in entering and exiting this level
+	in mWatts.uSec
+- qcom,time-overhead: The time spent in entering and exiting this level in uS
+
+Example:
+
+qcom,lpm-levels {
+	qcom,lpm-level@0 {
+		reg = <0>;
+		qcom,mode = <0>;        /* MSM_PM_SLEEP_MODE_WAIT_FOR_INTERRUPT */

+		qcom,vdd-mem-lower-bound = <1050000>; /* ACTIVE */
+		qcom,vdd-dig-upper-bound = <1150000>; /* MAX */

+* Power Management boot configuration (pm-boot)
+
+Low power management drivers need to specify the warmboot entry path for the
+application processors to resume from sleep/suspend. The boot configuration
+can vary if the core does/does not support a secure boot mode. The secure
+boot configuration boots the core sets up the core sub system registers and
+calls into the kernel entry point. In the absence of a secure boot mode, the
+core when powered on from reset will need to be configured with the warmboot
+entry pointer. The physical and the virtual address for the entry pointer
+need to provided to the driver.

+The device tree parameters for pm-boot are:

+Required parameters:

+/**
+ * DOC: MPQ Stream Buffer
+ *
+ * A stream buffer implmenetation used to transfer data between two units
+ * such as demux and decoders. The implementation relies on dvb_ringbuffer
+ * implementation. Refer to dvb_ringbuffer.h for details.
+ *
+ * The implementation uses two dvb_ringbuffers, one to pass the
+ * raw-data (PES payload for example) and the other to pass
+ * meta-data (information from PES header for example).
+ *
+ * The meta-data uses dvb_ringbuffer packet interface. Each meta-data
+ * packet hold the address and size of raw-data described by the
+ * meta-data packet, in addition to user's own parameters if any required.
+ *
+ * Contrary to dvb_ringbuffer implementation, this API makes sure there's
+ * enough data to read/write when making read/write operations.
+ * Users interested to flush/reset specific buffer, check for bytes
+ * ready or space available for write should use the respective services
+ * in dvb_ringbuffer (dvb_ringbuffer_avail, dvb_ringbuffer_free,
+ * dvb_ringbuffer_reset, dvb_ringbuffer_flush,
+ * dvb_ringbuffer_flush_spinlock_wakeup).
+ *
+ * Concurrency protection is handled in the same manner as in
+ * dvb_ringbuffer implementation.
+ *
+ * Typical call flow from producer:
+ *
+ * - Start writting the raw-data of new packet, the following call is
+ *   repeated until end of data of the specific packet
+ *
+ *     mpq_streambuffer_data_write(...)
+ *
+ * - Now write a new packet describing the new available raw-data
+ *     mpq_streambuffer_pkt_write(...)
+ *
+ * Typical call flow from consumer:
+ *
+ * - Poll for next available packet:
+ *      mpq_streambuffer_pkt_next(&streambuff,-1)
+ *
+ *   In different approach, consumer can wait on event for new data and then
+ *   call mpq_streambuffer_pkt_next, waiting for data can be done as follows:
+ *
+ *      wait_event_interruptible(
+ *			streambuff->packet_data->queue,
+ *			!dvb_ringbuffer_empty(&streambuff->packet_data) ||
+ *			(streambuff->packet_data.error != 0);
+ *
+ * - Get the new packet information:
+ *      mpq_streambuffer_pkt_read(..)
+ *
+ * - Read the raw-data of the new packet. Here you can use two methods:
+ *
+ *   1. Read the data to a user supplied buffer:
+ *         mpq_streambuffer_data_read()
+ *
+ *      In this case memory copy is done, read pointer is updated in the raw
+ *      data buffer, the amount of raw-data is provided part of the
+ *      packet's information. User should then call mpq_streambuffer_pkt_dispose
+ *      with dispose_data set to 0 as the raw-data was already disposed.
+ *
+ *   2. Access the data directly using the raw-data address. The address
+ *      of the raw data is provided part of the packet's information. User
+ *      then should call mpq_streambuffer_pkt_dispose with dispose_data set
+ *      to 1 to dispose the packet along with it's raw-data.
