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.

The values chosen for the names are alphabetically -sorted within a particular controller.

Thus, the -number of interrupt signals generated by a controller varies as a rough function -of the number of ports it implements.

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 hardware + 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. This binding currently defines no configuration mechanism for + this. By default, drivers should use register + GPIO_${port}_INTERRUPT_STATUS_G1_0.
