Microchip PIC32 Clock Controller Binding
----------------------------------------
Microchip clock controller is consists of few oscillators, PLL, multiplexer
and few divider modules.
This binding uses common clock bindings.
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
Required properties:
- compatible: shall be "microchip,pic32mzda-clk".
- reg: shall contain base address and length of clock registers.
- #clock-cells: shall be 1.
Optional properties:
- microchip,pic32mzda-sosc: shall be added only if platform has
secondary oscillator connected.
Example:
rootclk: clock-controller@1f801200 {
compatible = "microchip,pic32mzda-clk";
reg = <0x1f801200 0x200>;
#clock-cells = <1>;
/* optional */
microchip,pic32mzda-sosc;
};
The clock consumer shall specify the desired clock-output of the clock
controller (as defined in [2]) by specifying output-id in its "clock"
phandle cell.
[2] include/dt-bindings/clock/microchip,pic32-clock.h
For example for UART2:
uart2: serial@2 {
compatible = "microchip,pic32mzda-uart";
reg = <>;
interrupts = <>;
clocks = <&rootclk PB2CLK>;
};

Broadcom BCM6345-style Level 1 interrupt controller
This block is a first level interrupt controller that is typically connected
directly to one of the HW INT lines on each CPU.
Key elements of the hardware design include:
- 32, 64 or 128 incoming level IRQ lines
- Most onchip peripherals are wired directly to an L1 input
- A separate instance of the register set for each CPU, allowing individual
peripheral IRQs to be routed to any CPU
- Contains one or more enable/status word pairs per CPU
- No atomic set/clear operations
- No polarity/level/edge settings
- No FIFO or priority encoder logic; software is expected to read all
2-4 status words to determine which IRQs are pending
Required properties:
- compatible: should be "brcm,bcm<soc>-l1-intc", "brcm,bcm6345-l1-intc"
- reg: specifies the base physical address and size of the registers;
the number of supported IRQs is inferred from the size argument
- interrupt-controller: identifies the node as an interrupt controller
- #interrupt-cells: specifies the number of cells needed to encode an interrupt
source, should be 1.
- interrupt-parent: specifies the phandle to the parent interrupt controller(s)
this one is cascaded from
- interrupts: specifies the interrupt line(s) in the interrupt-parent controller
node; valid values depend on the type of parent interrupt controller
If multiple reg ranges and interrupt-parent entries are present on an SMP
system, the driver will allow IRQ SMP affinity to be set up through the
/proc/irq/ interface. In the simplest possible configuration, only one
reg range and one interrupt-parent is needed.
The driver operates in native CPU endian by default, there is no support for
specifying an alternative endianness.
Example:
periph_intc: interrupt-controller@10000000 {
compatible = "brcm,bcm63168-l1-intc", "brcm,bcm6345-l1-intc";
reg = <0x10000020 0x20>,
<0x10000040 0x20>;
interrupt-controller;
#interrupt-cells = <1>;
interrupt-parent = <&cpu_intc>;
interrupts = <2>, <3>;
};

hex "Relocation table size"
depends on RELOCATABLE
range 0x0 0x01000000
default "0x00100000"
---help---
A table of relocation data will be appended to the kernel binary
and parsed at boot to fix up the relocated kernel.
This option allows the amount of space reserved for the table to be
adjusted, although the default of 1Mb should be ok in most cases.
The build will fail and a valid size suggested if this is too small.
If unsure, leave at the default value.
config RANDOMIZE_BASE
bool "Randomize the address of the kernel image"
depends on RELOCATABLE
---help---
Randomizes the physical and virtual address at which the
kernel image is loaded, as a security feature that
deters exploit attempts relying on knowledge of the location
of kernel internals.
Entropy is generated using any coprocessor 0 registers available.
The kernel will be offset by up to RANDOMIZE_BASE_MAX_OFFSET.
If unsure, say N.
config RANDOMIZE_BASE_MAX_OFFSET
hex "Maximum kASLR offset" if EXPERT
depends on RANDOMIZE_BASE
range 0x0 0x40000000 if EVA || 64BIT
range 0x0 0x08000000
default "0x01000000"
---help---
When kASLR is active, this provides the maximum offset that will
be applied to the kernel image. It should be set according to the
amount of physical RAM available in the target system minus
PHYSICAL_START and must be a power of 2.
This is limited by the size of KSEG0, 256Mb on 32-bit or 1Gb with
EVA or 64-bit. The default is 16Mb.
