+
+DMA_ATTR_ALLOC_SINGLE_PAGES
+---------------------------
+
+This is a hint to the DMA-mapping subsystem that it's probably not worth
+the time to try to allocate memory to in a way that gives better TLB
+efficiency (AKA it's not worth trying to build the mapping out of larger
+pages). You might want to specify this if:
+- You know that the accesses to this memory won't thrash the TLB.
+ You might know that the accesses are likely to be sequential or
+ that they aren't sequential but it's unlikely you'll ping-pong
+ between many addresses that are likely to be in different physical
+ pages.
+- You know that the penalty of TLB misses while accessing the
+ memory will be small enough to be inconsequential. If you are
+ doing a heavy operation like decryption or decompression this
+ might be the case.
+- You know that the DMA mapping is fairly transitory. If you expect
+ the mapping to have a short lifetime then it may be worth it to
+ optimize allocation (avoid coming up with large pages) instead of
+ getting the slight performance win of larger pages.
+Setting this hint doesn't guarantee that you won't get huge pages, but it
+means that we won't try quite as hard to get them.
+
+NOTE: At the moment DMA_ATTR_ALLOC_SINGLE_PAGES is only implemented on ARM,
+though ARM64 patches will likely be posted soon.

The settings and programming routines for internal/external
MDIO are different. Must be included for internal MDIO.

+- For "fsl,fman-mdio" compatible internal mdio bus, the PHY is TBI PHY.
+- For "fsl,fman-memac-mdio" compatible internal mdio bus, the PHY is PCS PHY,
+ PCS PHY addr must be '0'.

+Standard Unit Suffixes for Property names
+
+Properties which have a unit of measure are recommended to have a unit
+suffix appended to the property name. The list below contains the
+recommended suffixes. Other variations exist in bindings, but should not
+be used in new bindings or added here. The inconsistency in the unit
+prefixes is due to selecting the most commonly used variants.
+
+It is also recommended to use the units listed here and not add additional
+unit prefixes.

+* Run Control and Power Management
+-------------------------------------------
+The RCPM performs all device-level tasks associated with device run control
+and power management.
+
+Required properites:
+ - reg : Offset and length of the register set of the RCPM block.
+ - fsl,#rcpm-wakeup-cells : The number of IPPDEXPCR register cells in the
+ fsl,rcpm-wakeup property.
+ - compatible : Must contain a chip-specific RCPM block compatible string
+ and (if applicable) may contain a chassis-version RCPM compatible
+ string. Chip-specific strings are of the form "fsl,<chip>-rcpm",
+ such as:
+ * "fsl,p2041-rcpm"
+ * "fsl,p5020-rcpm"
+ * "fsl,t4240-rcpm"
+
+ Chassis-version strings are of the form "fsl,qoriq-rcpm-<version>",
+ such as:
+ * "fsl,qoriq-rcpm-1.0": for chassis 1.0 rcpm
+ * "fsl,qoriq-rcpm-2.0": for chassis 2.0 rcpm
+ * "fsl,qoriq-rcpm-2.1": for chassis 2.1 rcpm
+
+All references to "1.0" and "2.0" refer to the QorIQ chassis version to
+which the chip complies.
+Chassis Version Example Chips
+--------------- -------------------------------
+1.0 p4080, p5020, p5040, p2041, p3041
+2.0 t4240, b4860, b4420
+2.1 t1040, ls1021
+
+Example:
+The RCPM node for T4240:
+ rcpm: global-utilities@e2000 {
+ compatible = "fsl,t4240-rcpm", "fsl,qoriq-rcpm-2.0";
+ reg = <0xe2000 0x1000>;
+ fsl,#rcpm-wakeup-cells = <2>;
+ };
+
+* Freescale RCPM Wakeup Source Device Tree Bindings
+-------------------------------------------
+Required fsl,rcpm-wakeup property should be added to a device node if the device
+can be used as a wakeup source.
+
+ - fsl,rcpm-wakeup: Consists of a phandle to the rcpm node and the IPPDEXPCR
+ register cells. The number of IPPDEXPCR register cells is defined in
+ "fsl,#rcpm-wakeup-cells" in the rcpm node. The first register cell is
+ the bit mask that should be set in IPPDEXPCR0, and the second register
+ cell is for IPPDEXPCR1, and so on.
+
+ Note: IPPDEXPCR(IP Powerdown Exception Control Register) provides a
+ mechanism for keeping certain blocks awake during STANDBY and MEM, in
+ order to use them as wake-up sources.
+
+Example:
+ lpuart0: serial@2950000 {
+ compatible = "fsl,ls1021a-lpuart";
+ reg = <0x0 0x2950000 0x0 0x1000>;
+ interrupts = <GIC_SPI 80 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&sysclk>;
+ clock-names = "ipg";
+ fsl,rcpm-wakeup = <&rcpm 0x0 0x40000000>;
+ };

+ Device-tree-compatible SH bootloaders are expected to provide the physical
+ address of the device tree blob in r4. Since legacy bootloaders did not
+ guarantee any particular initial register state, kernels built to
+ inter-operate with old bootloaders must either use a builtin DTB or

+ that does not use device tree. Support for the latter is being phased out
+ in favor of device tree.

========================
int (*match)(struct device * dev, struct device_driver * drv);
-match should return '1' if the driver supports the device, and '0'
-otherwise.
+match should return positive value if the driver supports the device,
+and zero otherwise. It may also return error code (for example
+-EPROBE_DEFER) if determining that given driver supports the device is
+not possible.
When a device is registered, the bus's list of drivers is iterated
over. bus->match() is called for each one until a match is found.

User API
========
+1. AFU character devices
+
For AFUs operating in AFU directed mode, two character device
files will be created. /dev/cxl/afu0.0m will correspond to a
master context and /dev/cxl/afu0.0s will correspond to a slave
reserved fields:
For future extensions and padding
+
+2. Card character device (powerVM guest only)
+
+ In a powerVM guest, an extra character device is created for the
+ card. The device is only used to write (flash) a new image on the
+ FPGA accelerator. Once the image is written and verified, the
+ device tree is updated and the card is reset to reload the updated
+ image.
+
+open
+----
+
+ Opens the device and allocates a file descriptor to be used with
+ the rest of the API. The device can only be opened once.
+
+ioctl
+-----
+
+CXL_IOCTL_DOWNLOAD_IMAGE:
+CXL_IOCTL_VALIDATE_IMAGE:
+ Starts and controls flashing a new FPGA image. Partial
+ reconfiguration is not supported (yet), so the image must contain
+ a copy of the PSL and AFU(s). Since an image can be quite large,
+ the caller may have to iterate, splitting the image in smaller
+ chunks.

- If this is set, kernel text and rodata will be made read-only. This
- is to help catch accidental or malicious attempts to change the

- text so it can be made explicitly non-executable. This creates
- another section-size padded region, so it can waste more memory
- space while gaining the read-only protections.

* -------- -------
* 0x00-0x0f original SH-3/4 syscall ABI (not in general use).
* 0x10-0x1f general SH-3/4 syscall ABI.
- * 0x20-0x2f syscall ABI for SH-2 parts.
+ * 0x1f unified SH-2/3/4 syscall ABI (preferred).
+ * 0x20-0x2f original SH-2 syscall ABI.
* 0x30-0x3f debug traps used by the kernel.
* 0x40-0xff Not supported by all parts, so left unhandled.
*
+ * For making system calls, any trap number in the range for the
+ * given cpu model may be used, but the unified trap number 0x1f is
+ * preferred for compatibility with all models.
+ *
+ * The low bits of the trap number were once documented as matching
+ * the number of arguments, but they were never actually used as such
+ * by the kernel. SH-2 originally used its own separate trap range
+ * because several hardware exceptions fell in the range used for the
+ * SH-3/4 syscall ABI.
+ *
+ * This code also handles delegating other traps to the BIOS/gdb stub.
+ *
* Note: When we're first called, the TRA value must be shifted
* right 2 bits in order to get the value that was used as the "trapa"
* argument.

+
+ `basename $0` DTx_1 DTx_2
+ diff DTx_1 and DTx_2
+
+
+ -f print full dts in diff (--unified=99999)
+ -h synonym for --help
+ -help synonym for --help
+ --help print this message and exit
+ -s SRCTREE linux kernel source tree is at path SRCTREE
+ (default is current directory)
+ -S linux kernel source tree is at root of current git repo
+ -u unsorted, do not sort DTx
+
+
+Each DTx is processed by the dtc compiler to produce a sorted dts source
+file. If DTx is a dts source file then it is pre-processed in the same
+manner as done for the compile of the dts source file in the Linux kernel
+build system ('#include' and '/include/' directives are processed).
+
+If two DTx are provided, the resulting dts source files are diffed.
+
+If DTx is a directory, it is treated as a DT subtree, such as
+ /proc/device-tree.
+
+If DTx contains the binary blob magic value in the first four bytes,
+ it is treated as a binary blob (aka .dtb or FDT).
+
+Otherwise DTx is treated as a dts source file (aka .dts).
+
+ If this script is not run from the root of the linux source tree,
+ and DTx utilizes '#include' or '/include/' then the path of the
+ linux source tree can be provided by '-s SRCTREE' or '-S' so that
+ include paths will be set properly.
+
+ The shell variable \${ARCH} must provide the architecture containing
+ the dts source file for include paths to be set properly for '#include'
+ or '/include/' to be processed.
+
+ If DTx_1 and DTx_2 are in different architectures, then this script
+ may not work since \${ARCH} is part of the include path. Two possible
+ workarounds:
+
+ `basename $0` \\
+ <(ARCH=arch_of_dtx_1 `basename $0` DTx_1) \\
+ <(ARCH=arch_of_dtx_2 `basename $0` DTx_2)
+
+ `basename $0` ARCH=arch_of_dtx_1 DTx_1 >tmp_dtx_1.dts
+ `basename $0` ARCH=arch_of_dtx_2 DTx_2 >tmp_dtx_2.dts
+ `basename $0` tmp_dtx_1.dts tmp_dtx_2.dts
+ rm tmp_dtx_1.dts tmp_dtx_2.dts
+
+ If DTx_1 and DTx_2 are in different directories, then this script will
+ add the path of DTx_1 and DTx_2 to the include paths. If DTx_2 includes
+ a local file that exists in both the path of DTx_1 and DTx_2 then the
+ file in the path of DTx_1 will incorrectly be included. Possible
+ workaround:
+
+ `basename $0` DTx_1 >tmp_dtx_1.dts
+ `basename $0` DTx_2 >tmp_dtx_2.dts
+ `basename $0` tmp_dtx_1.dts tmp_dtx_2.dts
