-clock support is added to the kernel.
-
-Required properties:
-
-- compatible: "ti,c64x+pll"
- May also have SoC-specific value to support SoC-specific initialization
- in the driver. One of:
- "ti,c6455-pll"

-Device State Configuration Registers
-------------------------------------
-
-TI C6X SoCs contain a region of miscellaneous registers which provide various
-function for SoC control or status. Details vary considerably among from SoC
-to SoC with no two being alike.
-
-In general, the Device State Configuration Registers (DSCR) will provide one or
-more configuration registers often protected by a lock register where one or
-more key values must be written to a lock register in order to unlock the
-configuration register for writes. These configuration register may be used to
-enable (and disable in some cases) SoC pin drivers, select peripheral clock
-sources (internal or pin), etc. In some cases, a configuration register is
-write once or the individual bits are write once. In addition to device config,
-the DSCR block may provide registers which are used to reset peripherals,
-provide device ID information, provide ethernet MAC addresses, as well as other
-miscellaneous functions.
-
-For device state control (enable/disable), each device control is assigned an
-id which is used by individual device drivers to control the state as needed.
-
-Required properties:
-
-- compatible: must be "ti,c64x+dscr"
-- reg: register area base and size
-
-Optional properties:
-
- NOTE: These are optional in that not all SoCs will have all properties. For
- SoCs which do support a given property, leaving the property out of the
- device tree will result in reduced functionality or possibly driver
- failure.
-
-- ti,dscr-devstat
- offset of the devstat register
-
-- ti,dscr-silicon-rev
- offset, start bit, and bitsize of silicon revision field
-
-- ti,dscr-rmii-resets
- offset and bitmask of RMII reset field. May have multiple tuples if more
- than one ethernet port is available.
-
-- ti,dscr-locked-regs
- possibly multiple tuples describing registers which are write protected by
- a lock register. Each tuple consists of the register offset, lock register
- offsset, and the key value used to unlock the register.
-
-- ti,dscr-kick-regs
- offset and key values of two "kick" registers used to write protect other
- registers in DSCR. On SoCs using kick registers, the first key must be
- written to the first kick register and the second key must be written to
- the second register before other registers in the area are write-enabled.
-
-- ti,dscr-mac-fuse-regs
- MAC addresses are contained in two registers. Each element of a MAC address
- is contained in a single byte. This property has two tuples. Each tuple has
- a register offset and four cells representing bytes in the register from
- most significant to least. The value of these four cells is the MAC byte
- index (1-6) of the byte within the register. A value of 0 means the byte
- is unused in the MAC address.
-
-- ti,dscr-devstate-ctl-regs
- This property describes the bitfields used to control the state of devices.
- Each tuple describes a range of identical bitfields used to control one or
- more devices (one bitfield per device). The layout of each tuple is:
-
- start_id num_ids reg enable disable start_bit nbits
-
- Where:
- start_id is device id for the first device control in the range
- num_ids is the number of device controls in the range
- reg is the offset of the register holding the control bits
- enable is the value to enable a device
- disable is the value to disable a device (0xffffffff if cannot disable)
- start_bit is the bit number of the first bit in the range
- nbits is the number of bits per device control
-
-- ti,dscr-devstate-stat-regs
- This property describes the bitfields used to provide device state status
- for device states controlled by the DSCR. Each tuple describes a range of
- identical bitfields used to provide status for one or more devices (one
- bitfield per device). The layout of each tuple is:
-
- start_id num_ids reg enable disable start_bit nbits
-
- Where:
- start_id is device id for the first device status in the range
- num_ids is the number of devices covered by the range
- reg is the offset of the register holding the status bits
- enable is the value indicating device is enabled
- disable is the value indicating device is disabled
- start_bit is the bit number of the first bit in the range
- nbits is the number of bits per device status
-
-- ti,dscr-privperm
- Offset and default value for register used to set access privilege for
- some SoC devices.
-
-
-Example:
-
- device-state-config-regs@2a80000 {
- compatible = "ti,c64x+dscr";
- reg = <0x02a80000 0x41000>;

-C6X Interrupt Chips
--------------------
-
-* C64X+ Core Interrupt Controller
-
- The core interrupt controller provides 16 prioritized interrupts to the
- C64X+ core. Priority 0 and 1 are used for reset and NMI respectively.
- Priority 2 and 3 are reserved. Priority 4-15 are used for interrupt
- sources coming from outside the core.
-
- Required properties:
- --------------------
- - compatible: Should be "ti,c64x+core-pic";
- - #interrupt-cells: <1>
-
- Interrupt Specifier Definition
- ------------------------------
- Single cell specifying the core interrupt priority level (4-15) where
- 4 is highest priority and 15 is lowest priority.
-
- Example
- -------
- core_pic: interrupt-controller@0 {
- interrupt-controller;
- #interrupt-cells = <1>;
- compatible = "ti,c64x+core-pic";
- };
-
-
-
-* C64x+ Megamodule Interrupt Controller
-
- The megamodule PIC consists of four interrupt mupliplexers each of which
- combine up to 32 interrupt inputs into a single interrupt output which
- may be cascaded into the core interrupt controller. The megamodule PIC
- has a total of 12 outputs cascading into the core interrupt controller.
- One for each core interrupt priority level. In addition to the combined
- interrupt sources, individual megamodule interrupts may be cascaded to
- the core interrupt controller. When an individual interrupt is cascaded,
- it is no longer handled through a megamodule interrupt combiner and is
- considered to have the core interrupt controller as the parent.
-
- Required properties:
- --------------------
- - compatible: "ti,c64x+megamod-pic"
- - interrupt-controller
- - #interrupt-cells: <1>
- - reg: base address and size of register area
- - interrupts: This should have four cells; one for each interrupt combiner.
- The cells contain the core priority interrupt to which the
- corresponding combiner output is wired.
-
- Optional properties:
- --------------------
- - ti,c64x+megamod-pic-mux: Array of 12 cells correspnding to the 12 core
- priority interrupts. The first cell corresponds to
- core priority 4 and the last cell corresponds to
- core priority 15. The value of each cell is the
- megamodule interrupt source which is MUXed to
- the core interrupt corresponding to the cell
- position. Allowed values are 4 - 127. Mapping for
- interrupts 0 - 3 (combined interrupt sources) are
- ignored.
-
- Interrupt Specifier Definition
- ------------------------------
- Single cell specifying the megamodule interrupt source (4-127). Note that
- interrupts mapped directly to the core with "ti,c64x+megamod-pic-mux" will
- use the core interrupt controller as their parent and the specifier will
- be the core priority level, not the megamodule interrupt number.
-
- Examples
- --------
- megamod_pic: interrupt-controller@1800000 {
- compatible = "ti,c64x+megamod-pic";
- interrupt-controller;
- #interrupt-cells = <1>;
- reg = <0x1800000 0x1000>;
- interrupt-parent = <&core_pic>;
- interrupts = < 12 13 14 15 >;
- };
-
- This is a minimal example where all individual interrupts go through a
- combiner. Combiner-0 is mapped to core interrupt 12, combiner-1 is mapped
- to interrupt 13, etc.
-
-
- megamod_pic: interrupt-controller@1800000 {
- compatible = "ti,c64x+megamod-pic";
- interrupt-controller;
- #interrupt-cells = <1>;
- reg = <0x1800000 0x1000>;
- interrupt-parent = <&core_pic>;
- interrupts = < 12 13 14 15 >;
- ti,c64x+megamod-pic-mux = < 0 0 0 0
- 32 0 0 0
- 0 0 0 0 >;
- };
-
- This the same as the first example except that megamodule interrupt 32 is
- mapped directly to core priority interrupt 8. The node using this interrupt
- must set the core controller as its interrupt parent and use 8 in the
- interrupt specifier value.

- * The Device State Control Registers (DSCR) provide SoC level control over
- * a number of peripherals. Details vary considerably among the various SoC
- * parts. In general, the DSCR block will provide one or more configuration
- * registers often protected by a lock register. One or more key values must
- * be written to a lock register in order to unlock the configuration register.
- * The configuration register may be used to enable (and disable in some
- * cases) SoC pin drivers, peripheral clock sources (internal or pin), etc.
- * In some cases, a configuration register is write once or the individual
- * bits are write once. That is, you may be able to enable a device, but
- * will not be able to disable it.
- *
- * In addition to device configuration, the DSCR block may provide registers
- * which are used to reset SoC peripherals, provide device ID information,
- * provide MAC addresses, and other miscellaneous functions.
