DPAA2 consists of sophisticated mechanisms for ++processing Ethernet packets, queue management, buffer management, ++autonomous L2 switching, virtual Ethernet bridging, and accelerator ++(e.g. crypto) sharing. ++ ++A DPAA2 hardware component called the Management Complex (or MC) manages the ++DPAA2 hardware resources. The MC provides an object-based abstraction for ++software drivers to use the DPAA2 hardware. ++The MC uses DPAA2 hardware resources such as queues, buffer pools, and ++network ports to create functional objects/devices such as network ++interfaces, an L2 switch, or accelerator instances. ++The MC provides memory-mapped I/O command interfaces (MC portals) ++which DPAA2 software drivers use to operate on DPAA2 objects. ++ ++The diagram below shows an overview of the DPAA2 resource management ++architecture:: ++ ++ +--------------------------------------+ ++ | OS | ++ | DPAA2 drivers | ++ | | | ++ +-----------------------------|--------+ ++ | ++ | (create,discover,connect ++ | config,use,destroy) ++ | ++ DPAA2 | ++ +------------------------| mc portal |-+ ++ | | | ++ | +- - - - - - - - - - - - -V- - -+ | ++ | | | | ++ | | Management Complex (MC) | | ++ | | | | ++ | +- - - - - - - - - - - - - - - -+ | ++ | | ++ | Hardware Hardware | ++ | Resources Objects | ++ | --------- ------- | ++ | -queues -DPRC | ++ | -buffer pools -DPMCP | ++ | -Eth MACs/ports -DPIO | ++ | -network interface -DPNI | ++ | profiles -DPMAC | ++ | -queue portals -DPBP | ++ | -MC portals ... | ++ | ... | ++ | | ++ +--------------------------------------+ ++ ++ ++The MC mediates operations such as create, discover, ++connect, configuration, and destroy.

In the example diagram below there ++are 8 objects of 5 types (DPMCP, DPIO, DPBP, DPNI, and DPMAC) ++in the container. ++ ++:: ++ ++ +---------------------------------------------------------+ ++ | DPRC | ++ | | ++ | +-------+ +-------+ +-------+ +-------+ +-------+ | ++ | | DPMCP | | DPIO | | DPBP | | DPNI | | DPMAC | | ++ | +-------+ +-------+ +-------+ +---+---+ +---+---+ | ++ | | DPMCP | | DPIO | | ++ | +-------+ +-------+ | ++ | | DPMCP | | ++ | +-------+ | ++ | | ++ +---------------------------------------------------------+ ++ ++From the point of view of an OS, a DPRC behaves similar to a plug and ++play bus, like PCI. DPRC commands can be used to enumerate the contents ++of the DPRC, discover the hardware objects present (including mappable ++regions and interrupts). ++ ++:: ++ ++ DPRC.1 (bus) ++ | ++ +--+--------+-------+-------+-------+ ++ | | | | | ++ DPMCP.1 DPIO.1 DPBP.1 DPNI.1 DPMAC.1 ++ DPMCP.2 DPIO.2 ++ DPMCP.3 ++ ++Hardware objects can be created and destroyed dynamically, providing ++the ability to hot plug/unplug objects in and out of the DPRC. ++ ++A DPRC has a mappable MMIO region (an MC portal) that can be used ++to send MC commands. It has an interrupt for status events (like ++hotplug). ++All objects in a container share the same hardware "isolation context". ++This means that with respect to an IOMMU the isolation granularity ++is at the DPRC (container) level, not at the individual object ++level. ++ ++DPRCs can be defined statically and populated with objects ++via a config file passed to the MC when firmware starts it. ++There is also a Linux user space tool called "restool" that can be ++used to create/destroy containers and objects dynamically. The latest ++version of restool can be found at: ++ https://github.com/qoriq-open-source/restool ++ ++DPAA2 Objects for an Ethernet Network Interface ++----------------------------------------------- ++ ++A typical Ethernet NIC is monolithic-- the NIC device contains TX/RX ++queuing mechanisms, configuration mechanisms, buffer management, ++physical ports, and interrupts. DPAA2 uses a more granular approach ++utilizing multiple hardware objects. Each object provides specialized ++functions. Groups of these objects are used by software to provide ++Ethernet network interface functionality. This approach provides ++efficient use of finite hardware resources, flexibility, and ++performance advantages. ++ ++The diagram below shows the objects needed for a simple ++network interface configuration on a system with 2 CPUs. ++ ++:: ++ ++ +---+---+ +---+---+ ++ CPU0 CPU1 ++ +---+---+ +---+---+ ++ | | ++ +---+---+ +---+---+ ++ DPIO DPIO ++ +---+---+ +---+---+ ++ \ / ++ \ / ++ \ / ++ +---+---+ ++ DPNI --- DPBP,DPMCP ++ +---+---+ ++ | ++ | ++ +---+---+ ++ DPMAC ++ +---+---+ ++ | ++ port/PHY ++ ++Below the objects are described.

The DPAA2 ++architecture separates the mechanism to access queues (the DPIO object) ++from the queues themselves. The DPIO provides an MMIO interface to ++enqueue/dequeue packets. To enqueue something a descriptor is written ++to the DPIO MMIO region, which includes the target queue number. ++There will typically be one DPIO assigned to each CPU. This allows all ++CPUs to simultaneously perform enqueue/dequeued operations. DPIOs are ++expected to be shared by different DPAA2 drivers. ++ ++- MMIO regions: queue operations, buffer management ++- IRQs: data availability, congestion notification, buffer ++ pool depletion ++- commands: IRQ config, enable, reset ++ ++DPBP (Datapath Buffer Pool) ++~~~~~~~~~~~~~~~~~~~~~~~~~~~ ++Represents a hardware buffer pool. ++ ++- MMIO regions: none ++- IRQs: none ++- commands: enable, reset ++ ++DPMCP (Datapath MC Portal) ++~~~~~~~~~~~~~~~~~~~~~~~~~~ ++Provides an MC command portal. ++Used by drivers to send commands to the MC to manage ++objects. ++ ++- MMIO regions: MC command portal ++- IRQs: command completion ++- commands: IRQ config, enable, reset ++ ++Object Connections ++================== ++Some objects have explicit relationships that must ++be configured: ++ ++- DPNI <--> DPMAC ++- DPNI <--> DPNI ++- DPNI <--> L2-switch-port ++ ++ A DPNI must be connected to something such as a DPMAC, ++ another DPNI, or L2 switch port. The DPNI connection ++ is made via a DPRC command. ++ ++:: ++ ++ +-------+ +-------+ ++ | DPNI | | DPMAC | ++ +---+---+ +---+---+ ++ | | ++ +==========+ ++ ++- DPNI <--> DPBP ++ ++ A network interface requires a 'buffer pool' (DPBP ++ object) which provides a list of pointers to memory ++ where received Ethernet data is to be copied. The ++ Ethernet driver configures the DPBPs associated with ++ the network interface. ++ ++Interrupts ++========== ++All interrupts generated by DPAA2 objects are message ++interrupts. At the hardware level message interrupts ++generated by devices will normally have 3 components-- ++1) a non-spoofable 'device-id' expressed on the hardware ++bus, 2) an address, 3) a data value. ++ ++In the case of DPAA2 devices/objects, all objects in the ++same container/DPRC share the same 'device-id'. ++For ARM-based SoC this is the same as the stream ID. ++ ++ ++DPAA2 Linux Drivers Overview ++============================ ++ ++This section provides an overview of the Linux kernel drivers for ++DPAA2-- 1) the bus driver and associated "DPAA2 infrastructure" ++drivers and 2) functional object drivers (such as Ethernet). ++ ++As described previously, a DPRC is a container that holds the other ++types of DPAA2 objects. It is functionally similar to a plug-and-play ++bus controller. ++Each object in the DPRC is a Linux "device" and is bound to a driver. ++The diagram below shows the Linux drivers involved in a networking ++scenario and the objects bound to each driver. A brief description ++of each driver follows. ++ ++:: ++ ++ +------------+ ++ | OS Network | ++ | Stack | ++ +------------+ +------------+ ++ | Allocator |. . . . . . . | Ethernet | ++ |(DPMCP,DPBP)| | (DPNI) | ++ +-.----------+ +---+---+----+ ++ . . ^ | ++ . . | | dequeue> ++ +-------------+ . | | ++ | DPRC driver | . +---+---V----+ +---------+ ++ | (DPRC) | . . . . . .| DPIO driver| | MAC | ++ +----------+--+ | (DPIO) | | (DPMAC) | ++ | +------+-----+ +-----+---+ ++ | | | ++ | | | ++ +--------+----------+ | +--+---+ ++ | MC-bus driver | | | PHY | ++ | | | |driver| ++ | /bus/fsl-mc | | +--+---+ ++ +-------------------+ | | ++ | | ++ ========================= HARDWARE =========|=================|====== ++ DPIO | ++ | | ++ DPNI---DPBP | ++ | | ++ DPMAC | ++ | | ++ PHY ---------------+ ++ ============================================|======================== ++ ++A brief description of each driver is provided below. ++ ++MC-bus driver ++------------- ++The MC-bus driver is a platform driver and is probed from a ++node in the device tree (compatible "fsl,qoriq-mc") passed in by boot ++firmware. It is responsible for bootstrapping the DPAA2 kernel ++infrastructure. ++Key functions include: ++ ++- registering a new bus type named "fsl-mc" with the kernel, ++ and implementing bus call-backs (e.g. match/uevent/dev_groups) ++- implementing APIs for DPAA2 driver registration and for device ++ add/remove ++- creates an MSI IRQ domain ++- doing a 'device add' to expose the 'root' DPRC, in turn triggering ++ a bind of the root DPRC to the DPRC driver ++ ++The binding for the MC-bus device-tree node can be consulted at ++*Documentation/devicetree/bindings/misc/fsl,qoriq-mc.txt*. ++The sysfs bind/unbind interfaces for the MC-bus can be consulted at ++*Documentation/ABI/testing/sysfs-bus-fsl-mc*. ++ ++DPRC driver ++----------- ++The DPRC driver is bound to DPRC objects and does runtime management ++of a bus instance. It performs the initial bus scan of the DPRC ++and handles interrupts for container events such as hot plug by ++re-scanning the DPRC. ++ ++Allocator ++--------- ++Certain objects such as DPMCP and DPBP are generic and fungible, ++and are intended to be used by other drivers. For example, ++the DPAA2 Ethernet driver needs: ++ ++- DPMCPs to send MC commands, to configure network interfaces ++- DPBPs for network buffer pools ++ ++The allocator driver registers for these allocatable object types ++and those objects are bound to the allocator when the bus is probed. ++The allocator maintains a pool of objects that are available for ++allocation by other DPAA2 drivers. ++ ++DPIO driver ++----------- ++The DPIO driver is bound to DPIO objects and provides services that allow ++other drivers such as the Ethernet driver to enqueue and dequeue data for ++their respective objects. ++Key services include: ++ ++- data availability notifications ++- hardware queuing operations (enqueue and dequeue of data) ++- hardware buffer pool management ++ ++To transmit a packet the Ethernet driver puts data on a queue and ++invokes a DPIO API. For receive, the Ethernet driver registers ++a data availability notification callback. To dequeue a packet ++a DPIO API is used. ++There is typically one DPIO object per physical CPU for optimum ++performance, allowing different CPUs to simultaneously enqueue ++and dequeue data. ++ ++The DPIO driver operates on behalf of all DPAA2 drivers ++active in the kernel-- Ethernet, crypto, compression, ++etc. ++ ++Ethernet driver ++--------------- ++The Ethernet driver is bound to a DPNI and implements the kernel ++interfaces needed to connect the DPAA2 network interface to ++the network stack. ++Each DPNI corresponds to a Linux network interface. ++ ++MAC driver ++---------- ++An Ethernet PHY is an off-chip, board specific component and is managed ++by the appropriate PHY driver via an mdio bus. The MAC driver ++plays a role of being a proxy between the PHY driver and the ++MC. It does this proxy via the MC commands to a DPMAC object. ++If the PHY driver signals a link change, the MAC driver notifies ++the MC via a DPMAC command. If a network interface is brought ++up or down, the MC notifies the DPMAC driver via an interrupt and ++the driver can take appropriate action. +--- a/MAINTAINERS ++++ b/MAINTAINERS +@@ -3980,6 +3980,12 @@ S: Maintained + F: drivers/char/dtlk.c + F: include/linux/dtlk.h + ++DPAA2 DATAPATH I/O (DPIO) DRIVER ++M: Roy Pledge ++L: linux-kernel@vger.kernel.org ++S: Maintained ++F: drivers/staging/fsl-mc/bus/dpio ++ + DPT_I2O SCSI RAID DRIVER + M: Adaptec OEM Raid Solutions + L: linux-scsi@vger.kernel.org +@@ -5110,7 +5116,10 @@ M: "J.

For compatible devices, the mask will be ORed into DEVDISR ++ or DEVDISR2 when the clock should be permenently disabled. + + Example: + +- power@b00 { +- compatible = "fsl,mpc8313-pmc", "fsl,mpc8349-pmc"; +- reg = <0xb00 0x100 0xa00 0x100>; +- interrupts = <80 8>; ++ power@e0070 { ++ compatible = "fsl,mpc8536-pmc", "fsl,mpc8548-pmc"; ++ reg = <0xe0070 0x20>; ++ ++ etsec1_clk: soc-clk@24 { ++ fsl,pmcdr-mask = <0x00000080>; ++ }; ++ etsec2_clk: soc-clk@25 { ++ fsl,pmcdr-mask = <0x00000040>; ++ }; ++ etsec3_clk: soc-clk@26 { ++ fsl,pmcdr-mask = <0x00000020>; ++ }; + }; --- a/drivers/cpufreq/Kconfig +++ b/drivers/cpufreq/Kconfig @@ -334,7 +334,7 @@ endif @@ -522,3 +613,418 @@ Signed-off-by: Yangbo Lu +} + +subsys_initcall(layerscape_rcpm_init); +--- /dev/null ++++ b/drivers/soc/fsl/sleep_fsm.c +@@ -0,0 +1,279 @@ ++/* ++ * deep sleep FSM (finite-state machine) configuration ++ * ++ * Copyright 2018 NXP ++ * ++ * Author: Hongbo Zhang ++ * Chenhui Zhao ++ * ++ * Redistribution and use in source and binary forms, with or without ++ * modification, are permitted provided that the following conditions are met: ++ * * Redistributions of source code must retain the above copyright ++ * notice, this list of conditions and the following disclaimer. ++ * * Redistributions in binary form must reproduce the above copyright ++ * notice, this list of conditions and the following disclaimer in the ++ * documentation and/or other materials provided with the distribution. ++ * * Neither the name of the above-listed copyright holders nor the ++ * names of any contributors may be used to endorse or promote products ++ * derived from this software without specific prior written permission. ++ * ++ * ALTERNATIVELY, this software may be distributed under the terms of the ++ * GNU General Public License ("GPL") as published by the Free Software ++ * Foundation, either version 2 of that License or (at your option) any ++ * later version. ++ * ++ * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" ++ * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE ++ * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ++ * ARE DISCLAIMED.
