====================
of_net: Add NVMEM support to of_get_mac_address

this patch series is a continuation of my previous attempt[1], where I've
tried to wire MTD layer into of_get_mac_address, so it would be possible to
load MAC addresses from various NVMEMs as EEPROMs etc.

Predecessor of this patch which used directly MTD layer has originated in
OpenWrt some time ago and supports already about 497 use cases in 357
device tree files.

During the review process of my 1st attempt I was told, that I shouldn't be
using MTD directly, but that I should rather use new NVMEM subsystem and
during the review process of v2 I was told, that I should handle
EPROBE_DEFFER error as well, during the review process of v3 I was told,
that returning pointer/NULL/ERR_PTR is considered as wrong API design, so
this v4 patch series tries to accommodate all this previous remarks.

First patch is wiring NVMEM support directly into of_get_mac_address as
it's obvious, that adding support for NVMEM into every other driver would
mean adding a lot of repetitive code. This patch allows us to configure MAC
addresses in various devices like ethernet and wireless adapters directly
from of_get_mac_address, which is used by quite a lot of drivers in the
tree already.

Second patch is simply updating documentation with NVMEM bits, and cleaning
up all current binding documentation referencing any of the MAC address
related properties.

Third and fourth patches are simply removing duplicate NVMEM code which is
no longer needed as the first patch has wired NVMEM support directly into
of_get_mac_address.

Patches 5-10 are converting all current users of of_get_mac_address to the
new ERR_PTR encoded error value, as of_get_mac_address could now return
valid pointer, NULL and ERR_PTR.

Just for a better picture, this patch series and one simple patch[2] on top
of it, allows me to configure 8Devices Carambola2 board's MAC addresses
with following DTS (simplified):

 &spi {
 	flash@0 {
 		partitions {
			art: partition@ff0000 {
				label = "art";
				reg = <0xff0000 0x010000>;
				read-only;

				nvmem-cells {
					compatible = "nvmem-cells";
					#address-cells = <1>;
					#size-cells = <1>;

					eth0_addr: eth-mac-addr@0 {
						reg = <0x0 0x6>;
					};

					eth1_addr: eth-mac-addr@6 {
						reg = <0x6 0x6>;
					};

					wmac_addr: wifi-mac-addr@1002 {
						reg = <0x1002 0x6>;
					};
				};
			};
		};
	};
 };

 &eth0 {
	nvmem-cells = <&eth0_addr>;
	nvmem-cell-names = "mac-address";
 };

 &eth1 {
	nvmem-cells = <&eth1_addr>;
	nvmem-cell-names = "mac-address";
 };

 &wmac {
	nvmem-cells = <&wmac_addr>;
	nvmem-cell-names = "mac-address";
 };

Many embedded devices have information such as MAC addresses stored
inside NVMEMs like EEPROMs and so on. Currently there are only two
drivers in the tree which benefit from NVMEM bindings.

Adding support for NVMEM into every other driver would mean adding a lot
of repetitive code. This patch allows us to configure MAC addresses in
various devices like ethernet and wireless adapters directly from
of_get_mac_address, which is already used by almost every driver in the
tree.

in OpenWrt some time ago and supports already about 497 use cases in 357

100GbE Intel Wired LAN Driver Updates 2019-05-04

This series contains updates to the ice driver only.

Jesse updated the driver to make more functions consistent in their use
of a local variable for vsi->back.  Updates the driver to use bit fields
when possible to avoid wasting lots of storage space to store single bit
values.  Optimized the driver to be more memory efficient by moving
structure members around that are not in are hot path.

Michal updates the driver to disable the VF if malicious device driver
(MDD) event is detected by the hardware.  Adds checks to validate the
messages coming from the VF driver.  Tightens up the sniffing of the
driver so that transmit traffic so that VF's cannot see what is on other
VSIs.

Tony fixed the driver so that receive stripping state won't change every
time transmit insertion is changed.  Cleanup the __always_unused
attribute, now that the variable is being used.  Fixed the function
which evaluates setting of features to ensure that can evaluate and set
multiple features in a single function call.

Akeem fixes the driver so that we do not attempt to remove a VLAN filter
that does not exist.  Adds support for adding a ethertype based filter
rule on VSI and describe it in a very long run-on sentence. :-)

Bruce cleans up static analysis warnings by removing a local variable
initialization that is not needed.

Brett makes the allocate/deallocate more consistent in all the driver
flows for VSI q_vectors.  In addition, makes setting/getting coalesce
settings more consistent throughout the driver.

switched to a new VLAN.  Fixed a typo in the link mode code, by using
the correct define.  Fixed truncation issue, which changed an function
argument to a smaller value that should have been a larger value.

Aleksandr adds support for new x710 devices and the speeds they support.

Sergey adds a check for the number of vectors against the number of MSIx
vectors to ensure one does not exceed the other.

Martyna adds additional input validation on VF messages handled by the
PF.  Fixed potential memory leaks in the driver where the error paths
were not freeing allocated memory.

Maciej reverts the double ShadowRAM checksum calculation change because
issues were found in the NVM downgrade situation.

Gustavo Silva changes the i40e driver to use struct_size() in kzalloc()
calls, to avoid type mistakes.
