Most Exynos SoCs share the common architecture +for buses. Generally, each bus of Exynos SoC includes a source clock +and a power line, which are able to change the clock frequency +of the bus in runtime. To monitor the usage of each bus in runtime, +the driver uses the PPMU (Platform Performance Monitoring Unit), which +is able to measure the current load of sub-blocks. + +The Exynos SoC includes the various sub-blocks which have the each AXI bus. +The each AXI bus has the owned source clock but, has not the only owned +power line. The power line might be shared among one more sub-blocks. +So, we can divide into two type of device as the role of each sub-block. +There are two type of bus devices as following: +- parent bus device +- passive bus device + +Basically, parent and passive bus device share the same power line. +The parent bus device can only change the voltage of shared power line +and the rest bus devices (passive bus device) depend on the decision of +the parent bus device. If there are three blocks which share the VDD_xxx +power line, Only one block should be parent device and then the rest blocks +should depend on the parent device as passive device. + + VDD_xxx |--- A block (parent) + |--- B block (passive) + |--- C block (passive) + +There are a little different composition among Exynos SoC because each Exynos +SoC has different sub-blocks. Therefore, such difference should be specified +in devicetree file instead of each device driver. In result, this driver +is able to support the bus frequency for all Exynos SoCs. + +Required properties for all bus devices: +- compatible: Should be "samsung,exynos-bus". +- clock-names : the name of clock used by the bus, "bus". +- clocks : phandles for clock specified in "clock-names" property. +- operating-points-v2: the OPP table including frequency/voltage information + to support DVFS (Dynamic Voltage/Frequency Scaling) feature. + +Required properties only for parent bus device: +- vdd-supply: the regulator to provide the buses with the voltage. +- devfreq-events: the devfreq-event device to monitor the current utilization + of buses. + +Required properties only for passive bus device: +- devfreq: the parent bus device. + +Optional properties only for parent bus device: +- exynos,saturation-ratio: the percentage value which is used to calibrate + the performance count against total cycle count. +- exynos,voltage-tolerance: the percentage value for bus voltage tolerance + which is used to calculate the max voltage. + +Detailed correlation between sub-blocks and power line according to Exynos SoC: +- In case of Exynos3250, there are two power line as following: + VDD_MIF |--- DMC + + VDD_INT |--- LEFTBUS (parent device) + |--- PERIL + |--- MFC + |--- G3D + |--- RIGHTBUS + |--- PERIR + |--- FSYS + |--- LCD0 + |--- PERIR + |--- ISP + |--- CAM + +- In case of Exynos4210, there is one power line as following: + VDD_INT |--- DMC (parent device) + |--- LEFTBUS + |--- PERIL + |--- MFC(L) + |--- G3D + |--- TV + |--- LCD0 + |--- RIGHTBUS + |--- PERIR + |--- MFC(R) + |--- CAM + |--- FSYS + |--- GPS + |--- LCD0 + |--- LCD1 + +- In case of Exynos4x12, there are two power line as following: + VDD_MIF |--- DMC + + VDD_INT |--- LEFTBUS (parent device) + |--- PERIL + |--- MFC(L) + |--- G3D + |--- TV + |--- IMAGE + |--- RIGHTBUS + |--- PERIR + |--- MFC(R) + |--- CAM + |--- FSYS + |--- GPS + |--- LCD0 + |--- ISP + +- In case of Exynos5422, there are two power line as following: + VDD_MIF |--- DREX 0 (parent device, DRAM EXpress controller) + |--- DREX 1 + + VDD_INT |--- NoC_Core (parent device) + |--- G2D + |--- G3D + |--- DISP1 + |--- NoC_WCORE + |--- GSCL + |--- MSCL + |--- ISP + |--- MFC + |--- GEN + |--- PERIS + |--- PERIC + |--- FSYS + |--- FSYS2 + +Example1: + Show the AXI buses of Exynos3250 SoC.

This binding document applies to both controllers. The register +layouts for the controllers share many similarities, but also some significant +differences. Hence, this document describes closely related but different +bindings and compatible values. + +The Tegra186 GPIO controller allows software to set the IO direction of, and +read/write the value of, numerous GPIO signals. Routing of GPIO signals to +package balls is under the control of a separate pin controller HW block. Two +major sets of registers exist: + +a) Security registers, which allow configuration of allowed access to the GPIO +register set. These registers exist in a single contiguous block of physical +address space. The size of this block, and the security features available, +varies between the different GPIO controllers. + +Access to this set of registers is not necessary in all circumstances. Code +that wishes to configure access to the GPIO registers needs access to these +registers to do so. Code which simply wishes to read or write GPIO data does not +need access to these registers. + +b) GPIO registers, which allow manipulation of the GPIO signals. In some GPIO +controllers, these registers are exposed via multiple "physical aliases" in +address space, each of which access the same underlying state. See the hardware +documentation for rationale. Any particular GPIO client is expected to access +just one of these physical aliases. + +Tegra HW documentation describes a unified naming convention for all GPIOs +implemented by the SoC. Each GPIO is assigned to a port, and a port may control +a number of GPIOs. Thus, each GPIO is named according to an alphabetical port +name and an integer GPIO name within the port. For example, GPIO_PA0, GPIO_PN6, +or GPIO_PCC3. + +The number of ports implemented by each GPIO controller varies. The number of +implemented GPIOs within each port varies. GPIO registers within a controller +are grouped and laid out according to the port they affect. + +The mapping from port name to the GPIO controller that implements that port, and +the mapping from port name to register offset within a controller, are both +extremely non-linear. The header file <dt-bindings/gpio/tegra186-gpio.h> +describes the port-level mapping. In that file, the naming convention for ports +matches the HW documentation. The values chosen for the names are alphabetically +sorted within a particular controller. Drivers need to map between the DT GPIO +IDs and HW register offsets using a lookup table. + +Each GPIO controller can generate a number of interrupt signals. Each signal +represents the aggregate status for all GPIOs within a set of ports. Thus, the +number of interrupt signals generated by a controller varies as a rough function +of the number of ports it implements. Note that the HW documentation refers to +both the overall controller HW module and the sets-of-ports as "controllers". + +Each GPIO controller in fact generates multiple interrupts signals for each set +of ports. Each GPIO may be configured to feed into a specific one of the +interrupt signals generated by a set-of-ports. The intent is for each generated +signal to be routed to a different CPU, thus allowing different CPUs to each +handle subsets of the interrupts within a port. The status of each of these +per-port-set signals is reported via a separate register. Thus, a driver needs +to know which status register to observe.

Each such "pad" may control either one or multiple lanes, +and thus contains any logic common to all its lanes.

Other lanes are for various types of low-speed, full-speed +or high-speed USB (such as UTMI, ULPI and HSIC). The XUSB pad controller +contains a software-configurable mux that sits between the I/O controller +ports (e.g. PCIe) and the lanes. + +In addition to per-lane configuration, USB 3.0 ports may require additional +settings on a per-board basis. + +Pads will be represented as children of the top-level XUSB pad controller +device tree node.

This is confusing since +"port" is typically used to denote the physical USB receptacle. The device +tree binding in this document uses the term "port" to refer to the logical +abstraction of the signals that are routed to a USB receptacle (i.e. a PHY +for the USB signal, the VBUS power supply, the USB 2.0 companion port for +USB 3.0 receptacles, ...). + +Required properties: +-------------------- +- compatible: Must be: + - Tegra124: "nvidia,tegra124-xusb-padctl" + - Tegra132: "nvidia,tegra132-xusb-padctl", "nvidia,tegra124-xusb-padctl" + - Tegra210: "nvidia,tegra210-xusb-padctl" +- reg: Physical base address and length of the controller's registers. +- resets: Must contain an entry for each entry in reset-names. +- reset-names: Must include the following entries: + - "padctl" + + +Pad nodes: +========== + +A required child node named "pads" contains a list of subnodes, one for each +of the pads exposed by the XUSB pad controller.
