c51aa14be9 dt-bindings: net: cdns,macb: add Mobileye EyeQ5 ethernet interface
Add "cdns,eyeq5-gem" as compatible for the integrated GEM block inside
Mobileye EyeQ5 SoCs. It is different from other compatibles in two main
ways: (1) it requires a generic PHY and (2) it is better to keep TCP
Segmentation Offload (TSO) disabled.

9665aa15ef dt-bindings: net: cdns,macb: allow tsu_clk without tx_clk
Allow providing tsu_clk without a tx_clk as both are optional.

This is about relaxing unneeded constraints. It so happened that in the
past HW that needed a tsu_clk always needed a tx_clk.

8dacfd92db dt-bindings: net: cdns,macb: add sama7d65 ethernet interface
This patch set adds all the supported FLEXCOMs for the SAMA7D65 SoC.
This also adds the GMAC interfaces and enables GMAC0 interface for
the SAMA7D65 SoC.

With the FLEXCOMs added to the SoC the MCP16502 and the MAC address
EEPROM are both added to flexcom10.

The dt-binding for USART is here [1]. And the dt-binding for DMA has
been applied here [2].

The original thread for this is here [3]. The applied changes have been
removed for this resend

f0ceedd52a dt-bindings: xilinx: Deprecate header with firmware constants
Firmware contants do not fit the purpose of bindings because they are not
independent IDs for abstractions. They are more or less just contants which
better to wire via header with DT which is using it.
That's why add deprecated message to dt binding header and also update
existing dt bindings not to use macros from the header  and replace them by
it's value. Actually value is not relevant because it is only example.

The similar changes have been done by commit 9d92925768 ("dt-bindings:
pinctrl: samsung: deprecate header with register constants").

26202873bb, hence clean out the

AVR32 architecture never supported device tree, hence this code was not

4e71ed9853 dt-bindings: Fix properties without any type
Now that the schema tools can extract type information for all
properties (in order to decode dtb files), finding properties missing
any type definition is fairly trivial though not yet automated.

Fix the various property schemas which are missing a type. Most of these
tend to be device specific properties which don't have a vendor prefix.
A vendor prefix is how we normally ensure a type is defined.
