Subject: [PATCH 1/2] spi: make spi-max-frequency optional
We only need a spi-max-frequency when we specifically request a
spi frequency lower than the max speed of spi host.
This property is already documented as optional property and current
host drivers are implemented to operate at highest speed possible
when spi->max_speed_hz is 0.
This patch makes spi-max-frequency an optional property so that
we could just omit it to use max controller speed.

Subject: [PATCH 2/2] spi: add support for mediatek spi-nor controller
This is a driver for mtk spi-nor controller using spi-mem interface.
The same controller already has limited support provided by mtk-quadspi
driver under spi-nor framework and this new driver is a replacement
for the old one.
Comparing to the old driver, this driver has following advantages:
1. It can handle any full-duplex spi transfer up to 6 bytes, and
this is implemented using generic spi interface.
2. It take account into command opcode properly. The reading routine
in this controller can only use 0x03 or 0x0b as opcode on 1-1-1
transfers, but old driver doesn't implement this properly. This
driver checks supported opcode explicitly and use (1) to perform
unmatched operations.
3. It properly handles SFDP reading. Old driver can't read SFDP
due to the bug mentioned in (2).
4. It can do 1-2-2 and 1-4-4 fast reading on spi-nor. These two ops
requires parsing SFDP, which isn't possible in old driver. And
the old driver is only flagged to support 1-1-2 mode.
5. It takes advantage of the DMA feature in this controller for
long reads and supports IRQ on DMA requests to free cpu cycles
from polling status registers on long DMA reading. It achieves
up to 17.5MB/s reading speed (1-4-4 mode) which is way faster
than the old one. IRQ is implemented as optional to maintain
backward compatibility.

Subject: [PATCH] net: phylink: propagate resolved link config via
mac_link_up()
Propagate the resolved link parameters via the mac_link_up() call for
MACs that do not automatically track their PCS state. We propagate the
link parameters via function arguments so that inappropriate members
of struct phylink_link_state can't be accessed, and creating a new
structure just for this adds needless complexity to the API.

Subject: [PATCH] net: dsa: mt7530: Extend device data ready for adding a
new hardware
Add a structure holding required operations for each device such as device
initialization, PHY port read or write, a checker whether PHY interface is
supported on a certain port, MAC port setup for either bus pad or a
specific PHY interface.
The patch is done for ready adding a new hardware MT7531, and keep the
same setup logic of existing hardware.

There are two independent PCIe controllers in MT2712/MT7622 platform,
and each of them should contain an independent MSI domain.
In current architecture, MSI domain will be inherited from the root
bridge, and all of the devices will share the same MSI domain.
Hence that, the PCIe devices will not work properly if the irq number
which required is more than 32.
Split the PCIe node for MT2712/MT7622 platform to fix MSI issue and
comply with the hardware design.
