Here is the quote from [1]:
The unit-address must match the first address specified
in the reg property of the node. If the node has no reg property,
the @ and unit-address must be omitted and the node-name alone

The DT fragment will select the ohci-platform driver, since that can
handle the JZ4740 OHCI just fine. While I don't have a JZ4740-based
board with anything connected to the USB host controller, I did test
the generic OHCI driver successfully on a JZ4770-based board.The device is disabled by default; boards that want to use it can
override the "status" property. The mass-production Qi LB60 boards
don't use the USB host controller.Signed-off-by: Maarten ter Huurne

This tool is based on the x86/boot/tools/relocs tool.
It parses the relocations present in the vmlinux elf file, building a
table of relocations that will be necessary to run the kernel from an
address other than its link address. This table is inserted into the
vmlinux elf, in the .data.relocs section. The table is subsequently used
by the code in arch/mips/kernel/relocate.c (added later) to relocate the
kernel.The tool, by default, also marks all relocation sections as 0 length.
This is due to objcopy currently being unable to handle copying the
relocations between 64 and 32 bit elf files as is done when building a
64 bit kernel.Signed-off-by: Matt Redfearn

Current ath79 clock.c code does not read reference clock and
pll setup from devicetree. E.g. you can set any clock rate value
in board DTS but it will have no effect on the real clk calculation.This patch fixes some AR9132 devicetree clock support defects:
* clk initialization function ath79_clocks_init_dt_ng()
is introduced; it actually gets pll block base register
address and reference clock from devicetree;
* pll register parsing code is moved to the separate
ar724x_clk_init() function; this function
can be called from platform code or from devicetree code.Also mips_hpt_frequency value is set from dt, so the appropriate
clock parameter is added to the cpu@0 devicetree node.The same approach can be used for adding AR9331 devicetree support.

Here are some Sascha Hauer's arguments for using aliases in the dts
files:- using aliases reduces the number of indentations in dts files;
- dts files become independent of the layout of the dtsi files
(it becomes possible to introduce another bus {} hierarchy between
a toplevel bus and the devices when you have to);- less chances for typos. if &i2c2 does not exist you get an error.
If instead you duplicate the whole path in the dts file a typo
in the path will just create another node.Signed-off-by: Antony Pavlov

The TP-LINK TL-WR1043ND board has only one serial port,
so replacing the default of 0 with 0 does nothing useful.Moreover, the correct name for aliases node is "aliases" not "alias".
An overview of the "aliases" node usage can be found
on the device tree usage page at devicetree.org [1].Also please see chapter 3.3 ("Aliases node") of the ePAPR 1.1 [2].

Current ath79 clock.c code does not read reference clock and

recreates the clocks from scratch so devicetree clock

that kernel does not boot anymore. The SPI and UART drivers
can't get clk; here are the bootlog error messages:of_serial: probe of 18020000.uart failed with error -22
ath79-spi: probe of 1f000000.spi failed with error -22The problem is that clock code assumes that reference clock
name is "ref" but current dts-file uses another name: "oscillator".This patch fixes the problem by changing external oscillator
dt node name to "ref".Please note that there is an alternative solution for the problem:

Commit 29bb45f25ff3 (regmap-mmio: Use native endianness for read/write)
attempted to fix some long standing bugs in the MMIO implementation for
big endian systems caused by duplicate byte swapping in both regmap and
readl()/writel() which affected MIPS systems as when they are in big
endian mode they flip the endianness of all registers in the system, not
just the CPU. MIPS systems had worked around this by declaring regmap
using IPs as little endian which is inaccurate, unfortunately the issue
had not been reported.Sadly the fix makes things worse rather than better. By changing the
behaviour to match the documentation it caused behaviour changes for
other IPs which broke them and by using the __raw I/O accessors to avoid
the endianness swapping in readl()/writel() it removed some memory
ordering guarantees and could potentially generate unvirtualisable
instructions on some architectures.Unfortunately sorting out all this mess in any half way sensible fashion
was far too invasive to go in during an -rc cycle so instead let's go
back to the old broken behaviour for v4.5, the better fixes are already
queued for v4.6. This does mean that we keep the broken MIPS DTs for
another release but that seems the least bad way of handling the
situation.Reported-by: Johannes Berg

On many MIPS systems the endianness of IP blocks is kept the same as
that of the CPU by the hardware. This includes the system controllers
on these systems which are controlled via syscon which uses the regmap
API which used readl() and writel() to interact with the hardware,
meaning that all writes are converted to little endian when writing to
the hardware. This caused a bad interaction with the regmap core in big
endian mode since it was not aware of the byte swapping and so ended up
performing little endian writes.Unfortunately when this issue was noticed it was addressed by updating
the DT for the affected devices to specify them as little endian. This
happened to work since it resulted in two endianness swaps which
cancelled each other out and gave little endian behaviour but meant that
the DT was clearly not accurately describing the hardware.The intention of commit 29bb45f25ff305 (regmap-mmio: Use native
endianness for read/write) was to fix this by making regmap default to
native endianness but this breaks most other MMIO users where the
hardware has a fixed endianness and the implementation uses the __raw
accessors which are not intended to be used outside of architecture
code. Instead use the newly added native-endian DT property to say
exactly what we want for these systems.Fixes: 29bb45f25ff305 (regmap-mmio: Use native endianness for read/write)

Add dummy.o to the targets list, and fill targets automatically from
$(vmlinuzobjs) to avoid having to maintain two lists.When building with XZ compression copy ashldi3.c to the build
directory to use a different object file for the kernel and zboot.
Without this the same object file need to be build with different
flags which cause a rebuild at every run.Signed-off-by: Alban Bedel
