Intel IXP4xx XScale Networking Processors GPIO
This GPIO controller is found in the Intel IXP4xx processors.
It supports 16 GPIO lines.
The interrupt portions of the GPIO controller is hierarchical:
the synchronous edge detector is part of the GPIO block, but the
actual enabling/disabling of the interrupt line is done in the
main IXP4xx interrupt controller which has a 1:1 mapping for
the first 12 GPIO lines to 12 system interrupts.
The remaining 4 GPIO lines can not be used for receiving
interrupts.
The interrupt parent of this GPIO controller must be the
IXP4xx interrupt controller.
Required properties:
- compatible : Should be
"intel,ixp4xx-gpio"
- reg : Should contain registers location and length
- gpio-controller : marks this as a GPIO controller
- #gpio-cells : Should be 2, see gpio/gpio.txt
- interrupt-controller : marks this as an interrupt controller
- #interrupt-cells : a standard two-cell interrupt, see
interrupt-controller/interrupts.txt
Example:
gpio0: gpio@c8004000 {
compatible = "intel,ixp4xx-gpio";
reg = <0xc8004000 0x1000>;

GPIO 14 and 15 can be used as clock outputs rather than GPIO,
and this can be enabled by a special flag.

MediaTek MT6358 Regulator
All voltage regulators provided by the MT6358 PMIC are described as the
subnodes of the MT6358 regulators node. Each regulator is named according
to its regulator type, buck_<name> and ldo_<name>. The definition for each
of these nodes is defined using the standard binding for regulators at
Documentation/devicetree/bindings/regulator/regulator.txt.
The valid names for regulators are::
BUCK:
buck_vdram1, buck_vcore, buck_vpa, buck_vproc11, buck_vproc12, buck_vgpu,
buck_vs2, buck_vmodem, buck_vs1
LDO:
ldo_vdram2, ldo_vsim1, ldo_vibr, ldo_vrf12, ldo_vio18, ldo_vusb, ldo_vcamio,
ldo_vcamd, ldo_vcn18, ldo_vfe28, ldo_vsram_proc11, ldo_vcn28, ldo_vsram_others,
ldo_vsram_gpu, ldo_vxo22, ldo_vefuse, ldo_vaux18, ldo_vmch, ldo_vbif28,
ldo_vsram_proc12, ldo_vcama1, ldo_vemc, ldo_vio28, ldo_va12, ldo_vrf18,
ldo_vcn33, ldo_vcama2, ldo_vmc, ldo_vldo28, ldo_vaud28, ldo_vsim2

ACPI device objects
===================
Generally speaking, there are two categories of devices in a system in which
ACPI is used as an interface between the platform firmware and the OS: Devices
that can be discovered and enumerated natively, through a protocol defined for
the specific bus that they are on (for example, configuration space in PCI),
without the platform firmware assistance, and devices that need to be described
by the platform firmware so that they can be discovered. Still, for any device
known to the platform firmware, regardless of which category it falls into,
there can be a corresponding ACPI device object in the ACPI Namespace in which
case the Linux kernel will create a struct acpi_device object based on it for
that device.
Those struct acpi_device objects are never used for binding drivers to natively
discoverable devices, because they are represented by other types of device
objects (for example, struct pci_dev for PCI devices) that are bound to by
device drivers (the corresponding struct acpi_device object is then used as
an additional source of information on the configuration of the given device).
Moreover, the core ACPI device enumeration code creates struct platform_device
objects for the majority of devices that are discovered and enumerated with the
help of the platform firmware and those platform device objects can be bound to
by platform drivers in direct analogy with the natively enumerable devices
case. Therefore it is logically inconsistent and so generally invalid to bind
drivers to struct acpi_device objects, including drivers for devices that are
discovered with the help of the platform firmware.
Historically, ACPI drivers that bound directly to struct acpi_device objects
were implemented for some devices enumerated with the help of the platform
firmware, but this is not recommended for any new drivers. As explained above,
platform device objects are created for those devices as a rule (with a few
exceptions that are not relevant here) and so platform drivers should be used
for handling them, even though the corresponding ACPI device objects are the
only source of device configuration information in that case.
For every device having a corresponding struct acpi_device object, the pointer
to it is returned by the ACPI_COMPANION() macro, so it is always possible to
get to the device configuration information stored in the ACPI device object
this way. Accordingly, struct acpi_device can be regarded as a part of the
interface between the kernel and the ACPI Namespace, whereas device objects of
other types (for example, struct pci_dev or struct platform_device) are used
for interacting with the rest of the system.
