+
+=====================================================================
+Overview
+
+DESCRIPTION
+
+SEC 4 h/w can process requests from 2 types of sources.
+1. DPAA Queue Interface (HW interface between Queue Manager & SEC 4).
+2. Job Rings (HW interface between cores & SEC 4 registers).
+
+High Speed Data Path Configuration:
+
+HW interface between QM & SEC 4 and also BM & SEC 4, on DPAA-enabled parts
+such as the P4080. The number of simultaneous dequeues the QI can make is
+equal to the number of Descriptor Controller (DECO) engines in a particular
+SEC version. E.g., the SEC 4.0 in the P4080 has 5 DECOs and can thus
+dequeue from 5 subportals simultaneously.
+
+Job Ring Data Path Configuration:
+
+Each JR is located on a separate 4k page, they may (or may not) be made visible
+in the memory partition devoted to a particular core. The P4080 has 4 JRs, so
+up to 4 JRs can be configured; and all 4 JRs process requests in parallel.
+
+=====================================================================
+SEC 4 Node

+Description
+
+ Node defines the base address of the SEC 4 block.
+ This block specifies the address range of all global
+ configuration registers for the SEC 4 block. It
+ also receives interrupts from the Run Time Integrity Check
+ (RTIC) function within the SEC 4 block.

+
+fsl,flexcan-v1.0 nodes
+-----------------------
+In addition to the required compatible-, reg- and interrupt-properties, you can
+also specify which clock source shall be used for the controller.
+
+CPI Clock- Can Protocol Interface Clock
+ This CLK_SRC bit of CTRL(control register) selects the clock source to
+ the CAN Protocol Interface(CPI) to be either the peripheral clock
+ (driven by the PLL) or the crystal oscillator clock. The selected clock
+ is the one fed to the prescaler to generate the Serial Clock (Sclock).
+ The PRESDIV field of CTRL(control register) controls a prescaler that
+ generates the Serial Clock (Sclock), whose period defines the
+ time quantum used to compose the CAN waveform.
+
+Can Engine Clock Source
+ There are two sources for CAN clock
+ - Platform Clock It represents the bus clock
+ - Oscillator Clock
+
+ Peripheral Clock (PLL)
+ --------------
+ |
+ --------- -------------
+ | |CPI Clock | Prescaler | Sclock
+ | |---------------->| (1.. 256) |------------>
+ --------- -------------
+ | |
+ -------------- ---------------------CLK_SRC
+ Oscillator Clock
+
+- fsl,flexcan-clock-source : CAN Engine Clock Source.This property selects
+ the peripheral clock. PLL clock is fed to the
+ prescaler to generate the Serial Clock (Sclock).
+ Valid values are "oscillator" and "platform"
+ "oscillator": CAN engine clock source is oscillator clock.
+ "platform" The CAN engine clock source is the bus clock
+ (platform clock).
+
+- fsl,flexcan-clock-divider : for the reference and system clock, an additional
+ clock divider can be specified.
+- clock-frequency: frequency required to calculate the bitrate for FlexCAN.
+
+Note:
+ - v1.0 of flexcan-v1.0 represent the IP block version for P1010 SOC.
+ - P1010 does not have oscillator as the Clock Source.So the default
+ Clock Source is platform clock.
+Examples:
+
+ can0@1c000 {
+ compatible = "fsl,flexcan-v1.0";
+ reg = <0x1c000 0x1000>;

+
+General Properties:
+
+ - compatible Should be "fsl,etsec-ptp"
+ - reg Offset and length of the register set for the device
+ - interrupts There should be at least two interrupts. Some devices
+ have as many as four PTP related interrupts.
+
+Clock Properties:
+
+ - fsl,tclk-period Timer reference clock period in nanoseconds.
+ - fsl,tmr-prsc Prescaler, divides the output clock.
+ - fsl,tmr-add Frequency compensation value.
+ - fsl,tmr-fiper1 Fixed interval period pulse generator.
+ - fsl,tmr-fiper2 Fixed interval period pulse generator.
+ - fsl,max-adj Maximum frequency adjustment in parts per billion.
+
+ These properties set the operational parameters for the PTP
+ clock. You must choose these carefully for the clock to work right.
+ Here is how to figure good values:
+
+ TimerOsc = system clock MHz
+ tclk_period = desired clock period nanoseconds
+ NominalFreq = 1000 / tclk_period MHz
+ FreqDivRatio = TimerOsc / NominalFreq (must be greater that 1.0)
+ tmr_add = ceil(2^32 / FreqDivRatio)
+ OutputClock = NominalFreq / tmr_prsc MHz
+ PulseWidth = 1 / OutputClock microseconds
+ FiperFreq1 = desired frequency in Hz
+ FiperDiv1 = 1000000 * OutputClock / FiperFreq1
+ tmr_fiper1 = tmr_prsc * tclk_period * FiperDiv1 - tclk_period
+ max_adj = 1000000000 * (FreqDivRatio - 1.0) - 1
+
+ The calculation for tmr_fiper2 is the same as for tmr_fiper1. The
+ driver expects that tmr_fiper1 will be correctly set to produce a 1
+ Pulse Per Second (PPS) signal, since this will be offered to the PPS
+ subsystem to synchronize the Linux clock.
+
+Example:
+
+ ptp_clock@24E00 {
+ compatible = "fsl,etsec-ptp";
+ reg = <0x24E00 0xB0>;
+ interrupts = <12 0x8 13 0x8>;

+ fsl,tmr-add = <0x999999A4>;
+ fsl,tmr-fiper1 = <0x3B9AC9F6>;
+ fsl,tmr-fiper2 = <0x00018696>;
+ fsl,max-adj = <659999998>;

+Required properties:
+- compatible: "fsl,mpic-global-timer"
+
+- reg : Contains two regions. The first is the main timer register bank
+ (GTCCRxx, GTBCRxx, GTVPRxx, GTDRxx). The second is the timer control
+ register (TCRx) for the group.
+
+- fsl,available-ranges: use <start count> style section to define which
+ timer interrupts can be used. This property is optional; without this,
+ all timers within the group can be used.
+
+- interrupts: one interrupt per timer in the group, in order, starting
+ with timer zero. If timer-available-ranges is present, only the
+ interrupts that correspond to available timers shall be present.

+---------------------------
+
+ There is one single entry point to the kernel, at the start
+ of the kernel image. That entry point supports two calling
+ conventions. A summary of the interface is described here. A full
+ description of the boot requirements is documented in
+ Documentation/arm/Booting
+
+ a) ATAGS interface. Minimal information is passed from firmware
+ to the kernel with a tagged list of predefined parameters.
+
+ r0 : 0
+
+ r1 : Machine type number
+
+ r2 : Physical address of tagged list in system RAM
+
+ b) Entry with a flattened device-tree block. Firmware loads the
+ physical address of the flattened device tree block (dtb) into r2,
+ r1 is not used, but it is considered good practise to use a valid
+ machine number as described in Documentation/arm/Booting.
+
+ r0 : 0
+
+ r1 : Valid machine type number. When using a device tree,
+ a single machine type number will often be assigned to
+ represent a class or family of SoCs.
+
+ r2 : physical pointer to the device-tree block
+ (defined in chapter II) in RAM. Device tree can be located
+ anywhere in system RAM, but it should be aligned on a 64 bit
+ boundary.
+
+ The kernel will differentiate between ATAGS and device tree booting by
+ reading the memory pointed to by r2 and looking for either the flattened
+ device tree block magic value (0xd00dfeed) or the ATAG_CORE value at
+ offset 0x4 from r2 (0x54410001).
