-bindings, consisting only of a compatible field, an address and
-possibly an interrupt line.
-
-If a device needs more specific bindings, such as properties to

-* ARM architected timer
-
-ARM cores may have a per-core architected timer, which provides per-cpu timers,
-or a memory mapped architected timer, which provides up to 8 frames with a
-physical and optional virtual timer per frame.
-
-The per-core architected timer is attached to a GIC to deliver its
-per-processor interrupts via PPIs. The memory mapped timer is attached to a GIC
-to deliver its interrupts via SPIs.
-
-** CP15 Timer node properties:
-
-- compatible : Should at least contain one of
-	"arm,armv7-timer"
-	"arm,armv8-timer"
-
-- interrupts : Interrupt list for secure, non-secure, virtual and
-  hypervisor timers, in that order.
-
-- clock-frequency : The frequency of the main counter, in Hz. Should be present
-  only where necessary to work around broken firmware which does not configure
-  CNTFRQ on all CPUs to a uniform correct value. Use of this property is
-  strongly discouraged; fix your firmware unless absolutely impossible.
-
-- always-on : a boolean property. If present, the timer is powered through an
-  always-on power domain, therefore it never loses context.
-
-- fsl,erratum-a008585 : A boolean property. Indicates the presence of
-  QorIQ erratum A-008585, which says that reading the counter is
-  unreliable unless the same value is returned by back-to-back reads.
-  This also affects writes to the tval register, due to the implicit
-  counter read.
-
-- hisilicon,erratum-161010101 : A boolean property. Indicates the
-  presence of Hisilicon erratum 161010101, which says that reading the
-  counters is unreliable in some cases, and reads may return a value 32
-  beyond the correct value. This also affects writes to the tval
-  registers, due to the implicit counter read.
-
-** Optional properties:
-
-- arm,cpu-registers-not-fw-configured : Firmware does not initialize
-  any of the generic timer CPU registers, which contain their
-  architecturally-defined reset values. Only supported for 32-bit
-  systems which follow the ARMv7 architected reset values.
-
-- arm,no-tick-in-suspend : The main counter does not tick when the system is in
-  low-power system suspend on some SoCs. This behavior does not match the
-  Architecture Reference Manual's specification that the system counter "must
-  be implemented in an always-on power domain."
-
-
-Example:
-
-	timer {
-		compatible = "arm,cortex-a15-timer",
-			     "arm,armv7-timer";
-		interrupts = <1 13 0xf08>,
-			     <1 14 0xf08>,
-			     <1 11 0xf08>,
-			     <1 10 0xf08>;
-		clock-frequency = <100000000>;
-	};
-
-** Memory mapped timer node properties:
-
-- compatible : Should at least contain "arm,armv7-timer-mem".
-
-- clock-frequency : The frequency of the main counter, in Hz. Should be present
-  only when firmware has not configured the MMIO CNTFRQ registers.
-
-- reg : The control frame base address.
-
-Note that #address-cells, #size-cells, and ranges shall be present to ensure
-the CPU can address a frame's registers.
-
-A timer node has up to 8 frame sub-nodes, each with the following properties:
-
-- frame-number: 0 to 7.
-
-- interrupts : Interrupt list for physical and virtual timers in that order.
-  The virtual timer interrupt is optional.
-
-- reg : The first and second view base addresses in that order. The second view
-  base address is optional.
-
-- status : "disabled" indicates the frame is not available for use. Optional.
-
-Example:
-
-	timer at f0000000 {
-		compatible = "arm,armv7-timer-mem";
-		#address-cells = <1>;
-		#size-cells = <1>;
-		ranges;
-		reg = <0xf0000000 0x1000>;
-		clock-frequency = <50000000>;
-
-		frame at f0001000 {
-			frame-number = <0>
-			interrupts = <0 13 0x8>,
-				     <0 14 0x8>;
-			reg = <0xf0001000 0x1000>,
-			      <0xf0002000 0x1000>;
-		};
-
-		frame at f0003000 {
-			frame-number = <1>
-			interrupts = <0 15 0x8>;
-			reg = <0xf0003000 0x1000>;

-=================
-ARM CPUs bindings
-=================
-
-The device tree allows to describe the layout of CPUs in a system through
-the "cpus" node, which in turn contains a number of subnodes (ie "cpu")
-defining properties for every cpu.
-
-Bindings for CPU nodes follow the Devicetree Specification, available from:
-
-https://www.devicetree.org/specifications/
-
-with updates for 32-bit and 64-bit ARM systems provided in this document.
-
-================================
-Convention used in this document
-================================
-
-This document follows the conventions described in the Devicetree
-Specification, with the addition:
-
-- square brackets define bitfields, eg reg[7:0] value of the bitfield in
-  the reg property contained in bits 7 down to 0
-
-=====================================
-cpus and cpu node bindings definition
-=====================================
-
-The ARM architecture, in accordance with the Devicetree Specification,
-requires the cpus and cpu nodes to be present and contain the properties
-described below.
-
-- cpus node
-
-	Description: Container of cpu nodes
-
-	The node name must be "cpus".
-
-	A cpus node must define the following properties:
-
-	- #address-cells
-		Usage: required
-		Value type: <u32>
-
-		Definition depends on ARM architecture version and
-		configuration:
-
-			# On uniprocessor ARM architectures previous to v7
-			  value must be 1, to enable a simple enumeration
-			  scheme for processors that do not have a HW CPU
-			  identification register.
-			# On 32-bit ARM 11 MPcore, ARM v7 or later systems
-			  value must be 1, that corresponds to CPUID/MPIDR
-			  registers sizes.
-			# On ARM v8 64-bit systems value should be set to 2,
-			  that corresponds to the MPIDR_EL1 register size.
-			  If MPIDR_EL1[63:32] value is equal to 0 on all CPUs
-			  in the system, #address-cells can be set to 1, since
-			  MPIDR_EL1[63:32] bits are not used for CPUs
-			  identification.

-			  this property is required and must be set to 0.
-
-			# On ARM 11 MPcore based systems this property is
-			  required and matches the CPUID[11:0] register bits.
-
-			  Bits [11:0] in the reg cell must be set to
-			  bits [11:0] in CPU ID register.
-
-			  All other bits in the reg cell must be set to 0.
-
-			# On 32-bit ARM v7 or later systems this property is
-			  required and matches the CPU MPIDR[23:0] register
-			  bits.
-
-			  Bits [23:0] in the reg cell must be set to
-			  bits [23:0] in MPIDR.
-
-			  All other bits in the reg cell must be set to 0.
-
-			# On ARM v8 64-bit systems this property is required
-			  and matches the MPIDR_EL1 register affinity bits.
-
-			  * If cpus node's #address-cells property is set to 2
-
-			    The first reg cell bits [7:0] must be set to
-			    bits [39:32] of MPIDR_EL1.
-
-			    The second reg cell bits [23:0] must be set to

-* ARM Performance Monitor Units
-
-ARM cores often have a PMU for counting cpu and cache events like cache misses
-and hits. The interface to the PMU is part of the ARM ARM. The ARM PMU
-representation in the device tree should be done as under:-
-
-Required properties:
-
-- compatible : should be one of
-	"apm,potenza-pmu"
-	"arm,armv8-pmuv3"
-	"arm,cortex-a73-pmu"

-- interrupts : 1 combined interrupt or 1 per core. If the interrupt is a per-cpu
-               interrupt (PPI) then 1 interrupt should be specified.
-
-Optional properties:
-
-- interrupt-affinity : When using SPIs, specifies a list of phandles to CPU
-                       nodes corresponding directly to the affinity of
-		       the SPIs listed in the interrupts property.
-
-                       When using a PPI, specifies a list of phandles to CPU
-		       nodes corresponding to the set of CPUs which have
-		       a PMU of this type signalling the PPI listed in the
-		       interrupts property, unless this is already specified
-		       by the PPI interrupt specifier itself (in which case
-		       the interrupt-affinity property shouldn't be present).
-
-                       This property should be present when there is more than
-		       a single SPI.
-
-
-- qcom,no-pc-write : Indicates that this PMU doesn't support the 0xc and 0xd
-                     events.
-
-- secure-reg-access : Indicates that the ARMv7 Secure Debug Enable Register
-		      (SDER) is accessible. This will cause the driver to do
-		      any setup required that is only possible in ARMv7 secure
-		      state. If not present the ARMv7 SDER will not be touched,
-		      which means the PMU may fail to operate unless external
-		      code (bootloader or security monitor) has performed the
-		      appropriate initialisation. Note that this property is
-		      not valid for non-ARMv7 CPUs or ARMv7 CPUs booting Linux
-		      in Non-secure state.
-
-Example:
-
-pmu {
-        compatible = "arm,cortex-a9-pmu";
-        interrupts = <100 101>;
-};

-* ARM Primecell Peripherals
-
-ARM, Ltd. Primecell peripherals have a standard id register that can be used to
-identify the peripheral type, vendor, and revision. This value can be used for
-driver matching.
-
-Required properties:
-
-- compatible : should be a specific name for the peripheral and
-               "arm,primecell".  The specific name will match the ARM
-               engineering name for the logic block in the form: "arm,pl???"
-
-Optional properties:
-
-- arm,primecell-periphid : Value to override the h/w value with
-- clocks : From common clock binding. First clock is phandle to clock for apb
-	pclk. Additional clocks are optional and specific to those peripherals.
-- clock-names : From common clock binding. Shall be "apb_pclk" for first clock.
-- dmas : From common DMA binding. If present, refers to one or more dma channels.
-- dma-names : From common DMA binding, needs to match the 'dmas' property.
-              Devices with exactly one receive and transmit channel shall name
-              these "rx" and "tx", respectively.
-- pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt
-- pinctrl-names : Names corresponding to the numbered pinctrl states
-- interrupts : one or more interrupt specifiers
-- interrupt-names : names corresponding to the interrupts properties
-
-Example:
-

-QCOM device tree bindings
--------------------------
-
-Some qcom based bootloaders identify the dtb blob based on a set of
-device properties like SoC and platform and revisions of those components.
-To support this scheme, we encode this information into the board compatible
-string.
-
-Each board must specify a top-level board compatible string with the following
-format:
-
-	compatible = "qcom,<SoC>[-<soc_version>][-<foundry_id>]-<board>[/<subtype>][-<board_version>]"
-
-The 'SoC' and 'board' elements are required. All other elements are optional.
-
-The 'SoC' element must be one of the following strings:
-
-	apq8016
-	apq8074
-	apq8084
-	apq8096
-	msm8916
-	msm8974
-	msm8992
-	msm8994
-	msm8996
-	mdm9615
-	ipq8074
-	sdm845
-
-The 'board' element must be one of the following strings:
-
-	cdp
-	liquid
-	dragonboard
-	mtp
-	sbc
-	hk01
-
-The 'soc_version' and 'board_version' elements take the form of v<Major>.<Minor>
-where the minor number may be omitted when it's zero, i.e.  v1.0 is the same
-as v1. If all versions of the 'board_version' elements match, then a
-wildcard '*' should be used, e.g. 'v*'.
-
-The 'foundry_id' and 'subtype' elements are one or more digits from 0 to 9.
-
-Examples:
-
-	"qcom,msm8916-v1-cdp-pm8916-v2.1"
-
-A CDP board with an msm8916 SoC, version 1 paired with a pm8916 PMIC of version
-2.1.
-
-	"qcom,apq8074-v2.0-2-dragonboard/1-v0.1"
-
-A dragonboard board v0.1 of subtype 1 with an apq8074 SoC version 2, made in
-foundry 2.
