"make dtbs_check":
arch/arm64/boot/dts/renesas/r8a77951-salvator-xs.dtb: clock-generator@6a: 'idt,shutdown' is a required property
From schema: Documentation/devicetree/bindings/clock/idt,versaclock5.yaml
arch/arm64/boot/dts/renesas/r8a77951-salvator-xs.dtb: clock-generator@6a: 'idt,output-enable-active' is a required property
From schema: Documentation/devicetree/bindings/clock/idt,versaclock5.yaml
Versaclock 5 clock generators can have their configuration stored in
One-Time Programmable (OTP) memory. Hence there is no need to specify
DT properties for manual configuration if the OTP has been programmed
before. Likewise, the Linux driver does not touch the SD/OE bits if the
corresponding properties are not specified, cfr. commit d83e561d43bc71e5
("clk: vc5: Add properties for configuring SD/OE behavior").
Reflect this in the bindings by making the "idt,shutdown" and
"idt,output-enable-active" properties not required, just like the
various "idt,*" properties in the per-output child nodes.
Fixes: 275e4e2dc0411508 ("dt-bindings: clk: vc5: Add properties for configuring the SD/OE pin")

devm_hwmon_device_unregister() has no in-tree user, and its implementation
is wrong since it does not pass the to-be-removed hardware monitoring
device as parameter. I do not envision a valid use for it; drivers needing
it should not have called devm_hwmon_device_register_with_info() in the
first place. Remove it.

Endpoint
Add reg-name: "dbi2", "atu" for i.MX8M PCIe Endpoint.
For i.MX8M PCIe EP, the dbi2 and atu addresses are pre-defined in the
driver. This method is not good.
In commit b7d67c6130ee ("PCI: imx6: Add iMX95 Endpoint (EP) support"),
Frank suggests to fetch the dbi2 and atu from DT directly. This commit is
preparation to do that for i.MX8M PCIe EP.
These changes wouldn't break driver function. When "dbi2" and "atu"
properties are present, i.MX PCIe driver would fetch the according base
addresses from DT directly. If only two reg properties are provided, i.MX
PCIe driver would fall back to the old method.

The LAN8650/1 combines a Media Access Controller (MAC) and an Ethernet
PHY to enable 10BASE-T1S networks. The Ethernet Media Access Controller
(MAC) module implements a 10 Mbps half duplex Ethernet MAC, compatible
with the IEEE 802.3 standard and a 10BASE-T1S physical layer transceiver
integrated into the LAN8650/1. The communication between the Host and the
MAC-PHY is specified in the OPEN Alliance 10BASE-T1x MACPHY Serial
Interface (TC6).

The IEEE 802.3cg project defines two 10 Mbit/s PHYs operating over a
single pair of conductors. The 10BASE-T1L (Clause 146) is a long reach
PHY supporting full duplex point-to-point operation over 1 km of single
balanced pair of conductors. The 10BASE-T1S (Clause 147) is a short reach
PHY supporting full / half duplex point-to-point operation over 15 m of
single balanced pair of conductors, or half duplex multidrop bus
operation over 25 m of single balanced pair of conductors.
Furthermore, the IEEE 802.3cg project defines the new Physical Layer
Collision Avoidance (PLCA) Reconciliation Sublayer (Clause 148) meant to
provide improved determinism to the CSMA/CD media access method. PLCA
works in conjunction with the 10BASE-T1S PHY operating in multidrop mode.
The aforementioned PHYs are intended to cover the low-speed / low-cost
applications in industrial and automotive environment. The large number
of pins (16) required by the MII interface, which is specified by the
IEEE 802.3 in Clause 22, is one of the major cost factors that need to be
addressed to fulfil this objective.
The MAC-PHY solution integrates an IEEE Clause 4 MAC and a 10BASE-T1x PHY
exposing a low pin count Serial Peripheral Interface (SPI) to the host
microcontroller. This also enables the addition of Ethernet functionality
to existing low-end microcontrollers which do not integrate a MAC
controller.

Add a netdev_dmabuf_binding struct which represents the
dma-buf-to-netdevice binding. The netlink API will bind the dma-buf to
rx queues on the netdevice. On the binding, the dma_buf_attach
& dma_buf_map_attachment will occur. The entries in the sg_table from
mapping will be inserted into a genpool to make it ready
for allocation.
The chunks in the genpool are owned by a dmabuf_chunk_owner struct which
holds the dma-buf offset of the base of the chunk and the dma_addr of
the chunk. Both are needed to use allocations that come from this chunk.
We create a new type that represents an allocation from the genpool:
net_iov. We setup the net_iov allocation size in the
genpool to PAGE_SIZE for simplicity: to match the PAGE_SIZE normally
allocated by the page pool and given to the drivers.
The user can unbind the dmabuf from the netdevice by closing the netlink
socket that established the binding. We do this so that the binding is
automatically unbound even if the userspace process crashes.
The binding and unbinding leaves an indicator in struct netdev_rx_queue
that the given queue is bound, and the binding is actuated by resetting
the rx queue using the queue API.
The netdev_dmabuf_binding struct is refcounted, and releases its
resources only when all the refs are released.

API takes the dma-buf fd as input, and binds it to the netdevice. The
user can specify the rx queues to bind the dma-buf to.
