@ -45,14 +45,24 @@ how the user addresses are used by the kernel:
1. User addresses not accessed by the kernel but used for address space
management (e.g. ``mprotect()``, ``madvise()``). The use of valid
tagged pointers in this context is allowed with the exception of
``brk()``, ``mmap()`` and the ``new_address`` argument to
``mremap()`` as these have the potential to alias with existing
user addresses.
tagged pointers in this context is allowed with these exceptions:
NOTE: This behaviour changed in v5.6 and so some earlier kernels may
incorrectly accept valid tagged pointers for the ``brk()``,
``mmap()`` and ``mremap()`` system calls.
- ``brk()``, ``mmap()`` and the ``new_address`` argument to

user addresses.
NOTE: This behaviour changed in v5.6 and so some earlier kernels may
incorrectly accept valid tagged pointers for the ``brk()``,

- The ``range.start``, ``start`` and ``dst`` arguments to the
``UFFDIO_*`` ``ioctl()``s used on a file descriptor obtained from
``userfaultfd()``, as fault addresses subsequently obtained by reading
the file descriptor will be untagged, which may otherwise confuse
tag-unaware programs.
NOTE: This behaviour changed in v5.14 and so some earlier kernels may
incorrectly accept valid tagged pointers for this system call.

relaxation is disabled by default and the application thread needs to

IMX8 glue layer controller, NXP imx8 families support Synopsys MAC 5.10a IP.
This file documents platform glue layer for IMX.
Please see stmmac.txt for the other unchanged properties.
The device node has following properties.
Required properties:
- compatible: Should be "nxp,imx8mp-dwmac-eqos" to select glue layer
and "snps,dwmac-5.10a" to select IP version.
- clocks: Must contain a phandle for each entry in clock-names.
- clock-names: Should be "stmmaceth" for the host clock.
Should be "pclk" for the MAC apb clock.
Should be "ptp_ref" for the MAC timer clock.
Should be "tx" for the MAC RGMII TX clock:
Should be "mem" for EQOS MEM clock.
- "mem" clock is required for imx8dxl platform.
- "mem" clock is not required for imx8mp platform.
- interrupt-names: Should contain a list of interrupt names corresponding to
the interrupts in the interrupts property, if available.
Should be "macirq" for the main MAC IRQ
Should be "eth_wake_irq" for the IT which wake up system
- intf_mode: Should be phandle/offset pair. The phandle to the syscon node which
encompases the GPR register, and the offset of the GPR register.
- required for imx8mp platform.
- is optional for imx8dxl platform.
Optional properties:
- intf_mode: is optional for imx8dxl platform.
- snps,rmii_refclk_ext: to select RMII reference clock from external.
Example:
eqos: ethernet@30bf0000 {

reg = <0x30bf0000 0x10000>;
