The MT753x switches provide a switch-internal MDIO bus for the embedded
PHYs.
Register a OF sub-node on the switch OF-node for this internal MDIO bus.
This allows to configure the embedded PHYs using device-tree.

Since CONFIG_DYNAMIC_DEBUG is already managed via the KERNEL_DYNAMIC_DEBUG
setting in Config-kernel.in (default N), remove or disable it in target
configs which unconditionally enable it, along with the related setting
CONFIG_DYNAMIC_DEBUG_CORE. This saves several KB in the kernels for
ipq40xx, ipq806x, filogic, mt7622, qoriq, and sunxi.

This activates CONFIG_SLAB_FREELIST_RANDOM.
This option make the free list less predictable. This makes it harder to

This adds a little bit more code to the kernel and a small additional

Early versions (?) of the RTL8221B PHY cannot be identified in a regular

correctly but returns 0 instead.
Implement custom identify function using the PKGID instead of iterating
over the implemented MMDs to work-around this problem.

This activates the following kernel options by default:
* CONFIG_RANDOM_TRUST_CPU
* CONFIG_RANDOM_TRUST_BOOTLOADER
With these option Linux will also use data from the CPU RNG e.g. RDRAND
and the bootloader to initialize the Linux RNG if such sources are
available.
These random bits are used in addition to the other sources, no other
sources are getting deactivated. I read that the Chacha mixer isn't
vulnerable to injected entropy, so this should not be a problem even if
these sources might inject bad random data.
The Linux kernel suggests to activate both options, Debian also
activates them. This does not increase kernel code size.

However, in the case of hack-5.15 patches which are not meant for

The previous attempt to replace an open coded paged read in the RealTek
Ethernet PHY driver was too naive and resulted in breaking the r8169
PCIe Ethernet driver which also makes use of the RealTek Ethernet PHY
driver.
Fix this by instead of using the (not yet populated) paged operations
rather use rtl821x_write_page and protect the whole paged read operation
using the MDIO bus mutex.

* use interface mode switching only when operating in C45 mode
Linux prevents switching the interface mode when using C22 MDIO,
hence use rate-adapter mode in case the PHY controlled via C22.
* use phy_read_paged where appropriate
* use existing generic inline functions to handle 10GbE advertisements
instead of redundantly defining register macros in realtek.c which
are not actually vendor-specific.
* make sure 10GbE advertisement is valid, preventing false-positive

Replace patches for MediaTek Ethernet driver SGMII/SerDes unit with

Signed-off-by: Daniel Golle <daniel@makrotopia.org>
It isn't feasible to literally backport all upstream phylink_pcs changes
down to Linux 5.15: It's just too many patches, and many downstream
drivers and hacks are likely to break. We are too close to branching off
to risk this, and it's also just too much work.
Instead just add helper functions used by modern PCS drivers while keeping
the original functions instact as well. While this may add a kilobyte or
two of extra kernel size, it has the advantage that we get the best of both
worlds: None of the existing codepaths are touched, but yet we have the
option to backport singular improvements to Ethernet drivers where needed.
