+Introduction
+============
+
+The MSM ADSPRPC driver implements an IPC (Inter-Processor Communication)
+mechanism that allows for clients to transparently make remote method
+invocations across processor boundaries.
+
+The below diagram depicts invocation of a single method where the client
+and objects reside on different processors. An object could expose
+multiple methods which can be grouped together and referred to as an
+interface.
+
+: ,--------, ,------, ,-----------, ,------, ,--------,
+: | | method | | | | | | method | |
+: | Client |------->| Stub |->| Transport |->| Skel |------->| Object |
+: | | | | | | | | | |
+: `--------` `------` `-----------` `------` `--------`
+
+Client: Linux user mode process that initiates the remote invocation
+Stub: Auto generated code linked in with the user mode process that
+ takes care of marshaling parameters
+Transport: Involved in carrying an invocation from a client to an
+ object. This involves two portions: 1) MSM ADSPRPC Linux
+ kernel driver that receives the remote invocation, queues
+ them up and then waits for the response after signaling the
+ remote side. 2) Service running on the remote side that
+ dequeues the messages from the queue and dispatches them for
+ processing.
+Skel: Auto generated code that takes care of un-marshaling
+ parameters
+Object: Method implementation
+
+Hardware description
+====================
+
+The driver interfaces with the components in the DSP subsystem and does
+not drive or manage any hardware resources.
+
+Software description
+====================
+
+The MSM ADSPRPC driver uses SMD (Shared Memory Driver) to send and
+receive messages with the remote processor. The SMD channel used for
+communication is opened during initialization of the driver and is
+closed when the driver module is unloaded. The driver does not expose
+HLOS memory to the remote processor but rather communication of
+invocation parameters happen over ION allocated buffers.
+
+The driver receives remote call invocations via an ioctl call. When a
+remote call invocation is received, the driver does the following:
+- Retrieves the invocation parameters
+- Copies input buffers in HLOS memory to ION allocated buffers
+- Allocates ION buffers for output buffers in HLOS memory as required
+- Scatter-gathers list of pages for ION allocated input and output
+ buffers
+- Coalesces information about the contiguous page buffers
+- Builds up a message with the received information
+- Sends the message to a remote processor through an SMD channel
+- Waits for a response from the remote processor through the SMD channel
+- Reads the message available from the shared memory SMD channel
+- Copies back from ION buffers to HLOS memory for output buffers
+- Returns the response of the remote invocation
+
+Design
+======
+
+The design goals of this transport mechanism are:
+- Fast and efficient ways to transfer huge buffers across
+ inter-processor boundaries
+- Zero copy of ION allocated buffers passed during invocations
+
+To achieve the zero copy approach of ION allocated user space buffers,
+the driver scatter-gathers the list of pages of the buffers being passed
+in. This information is then sent over to the remote processor for it
+to map into its address space.
+
+The invocation requests sent over the SMD channel carry context
+information as to whom the request is originating from. The responses
+received over the SMD channel have context information in the message
+which is then used to wake the thread waiting for a response.
+
+If the remote processor goes down and gets restarted, the SMD channel
+is re-initialized when the remote processor comes back up. An
+error code would be returned to the client for all invocations that
+happen before the SMD channel could get completely re-initialized.
+
+Power Management
+================
+
+None
+
+SMP/multi-core
+==============
+
+The driver uses semaphores to wake up clients waiting for a remote
+invocation response.
+
+Security
+========
+
+Use of the zero copy approach results in a page-size granularity of
+all buffers being passed to the remote processor. The objects that will
+be manipulating these buffers on the remote processor will be signed
+and trusted entities, thereby alleviating any fear of intentional
+scribbling of these buffers.
+
+Performance
+===========
+
+In order to minimize latencies across remote invocations:
+- messages exchanged between the remote processors are kept short
+- zero copy approach for ION allocated user space buffers
+
+Interface
+=========
+
+The driver exposes a user space interface through /dev/adsprpc-smd and
+the user space clients send commands to the driver by using the
+following ioctl command:
+
+- FASTRPC_IOCTL_INVOKE: Parameters passed in includes the buffers and
+ data related to remote invocation.
+
+ /*
+ * Information about the input/output buffer or an handle to the
+ * object being passed in the remote invocation
+ *
+ * @pv: Pointer to input/output buffer
+ * @len: Length of the input/output buffer
+ * @handle: Handle to the remote object
+ */
+ typedef union {
+ struct remote_buf {
+ void *pv;
+ int len;
+ } buf;
+ unsigned int handle;
+ } remote_arg;
+
+ /*
+ * Invocation parameters passed via ioctl call by the client
+ *
+ * @handle: Handle to the object on which the method is to be
+ * invoked
+ * @sc: Scalars detailing the parameters being passed in
+ * bits 0-3: Number of output handles
+ * bits 4-7: Number of input handles
+ * bits 8-15: Number of output buffers
+ * bits 16-23: Number of input buffers
+ * bits 24-28: Method to be invoked
+ * bits 29-31: Method attributes
+ * @pra: Remote arguments to be passed for method invocation
+ */

+Qualcomm's QPNP PMIC Battery Management System driver
+
+QPNP PMIC BMS provides interface to clients to read properties related
+to the battery. It's main function is to calculate the State of Charge (SOC),
+a 0-100 percentage representing the amount of charge left in the battery.
+
+BMS node
+
+Required properties:
+- compatible : should be "qcom,qpnp-bms" for the BM driver.
+- reg : offset and length of the PMIC BMS register map.
+- interrupts : the interrupt mappings for bms.
+ The format should be
+ <slave-id peripheral-id interrupt-number>.
+- interrupt-names : names for the mapped bms interrupt
+ The following interrupts are required:
+ 0 : vsense_for_r
+ 1 : vsense_avg
+ 2 : sw_cc_thr
+ 3 : ocv_thr
+ 4 : charge_begin
+ 5 : good_ocv
+ 6 : ocv_for_r
+ 7 : cc_thr
+- qcom,bms-r-sense-mohm : sensor resistance in in milli-ohms.
+- qcom,bms-v-cutoff-uv : cutoff voltage where the battery is considered dead in
+ micro-volts.
+- qcom,bms-max-voltage-uv : maximum voltage for the battery in micro-volts.
+- qcom,bms-r-conn-mohm : connector resistance in milli-ohms.
+- qcom,bms-shutdown-soc-valid-limit : If the ocv upon restart is within this
+ distance of the shutdown ocv, the BMS will try to force
+ the new SoC to the old one to provide charge continuity.
+ That is to say,
+ if (abs(shutdown-soc - current-soc) < limit)
+ then use old SoC.
+- qcom,bms-adjust-soc-low-threshold : The low threshold for the "flat portion"
+ of the charging curve. The BMS will not adjust SoC
+ based on voltage during this time.
+- qcom,bms-adjust-soc-high-threshold : The high threshold for the "flat
+ portion" of the charging curve. The BMS will not
+ adjust SoC based on voltage during this time.
+- qcom,bms-chg-term-ua : current in micro-amps when charging is considered done.
+ As soon as current passes this point, charging is
+ stopped.
+
+Example:
+ bms@4000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
