This commit introduces a port of the Linux kernel's driver for the
Mediatek's MT7621 I2C controller.
The port was undertaken as the existing driver intended for Mediatek
I2C controllers (mtk_i2c.c) is not compatible with the MT7621.
To use the driver:
1. Ensure that the mode of the i2c pin group is
configured for "i2c" rather than "gpio".
2. Delete the existing (bitbanged) i2c node from
arch/mips/dts/mt7621.dtsi, or specify:
/delete-node/ &i2c;
3. Declare:
i2c: i2c@1e000900 {
compatible = "mediatek,mt7621-i2c";
reg = <0x1e000900 0x100>;
clocks = <&clk50m>;
clock-names = "sys_clock";
resets = <&rstctrl RST_I2C>;
reset-names = "i2c_reset";
pinctrl-names = "default";
pinctrl-0 = <&i2c_pins>;
#address-cells = <1>;
#size-cells = <0>;
status = "okay";

Resync all defconfig files using qconfig.py
Signed-off-by: Tom Rini <[email protected]>

No big features this time, mostly a collection of patches that have been
lying around for a bit. There are some DT updates, for those SoCs that
do not use OF_UPSTREAM yet, hopefully that's the last time we need to do
this exercise. And that's offset by switching over two more SoCs to
OF_UPSTREAM. Two new boards get a defconfig, and some improvements for
the sun8i-emac Ethernet driver. Finally a patch that fixes occassional
DRAM size misdetection for new A523 boards.
There are a few outstanding patches that just wait for getting some
details confirmed, which I might send then later.
CI passed, and I tested this briefly on affected boards.

Sync the kernel devicetree source files for the Allwinner SoCs with
32-bit cores that do not use OF_UPSTREAM yet. The files were taken
from a v6.18-rc1 tree.
To maintain ABI compatibility with existing LTS kernels, one change
moving some IP blocks to the r_intc interrupt controller is excluded.
This effectively reverts Linux commits 994e5818392c and 9fdef3c3d8c2.
This commit also adds a new board devicetree for the A33 Vstar board,
plus one DT overlay for the OrangePi Zero interface board.
This update should not impact any existing U-Boot functionality.

Sync the devicetree files from the official Linux kernel tree, v6.18-rc1.
This is covering Allwinner SoCs with 64-bit ARM cores.
The bulk is cosmetic changes: board model name changes, DT node renames,
whitespace fixes.
The actual changes are not dramatic: the CPU cores get their caches
described properly, some A64 video clocks get fixed, some A64 boards
describe the header pins for the WiFi module, the Pinephone adds an
alternative magnetometer used on some board revisions.
On the H5 side the microSD slots get marked as having no write-protect
detection, and the NanoPi Neo Plus2 board describes its regulators better.
The H6 boards switch from RSB to I2C for their PMIC connection.
As before, this omits the non-backwards compatible changes to the R_INTC
controller, to remain compatible with older kernels.

In contrast to some other Allwinner SoCs, there is no difference between
the DTs for the Allwinner A80 SoCs (sun9i) between the U-Boot and the
Linux kernel repository.
Remove the old copies of the A80 related .dts and .dtsi files, and switch
most of sun9i boards over to use OF_UPSTREAM.
There is the Sunchip CX-A99 (family of) board(s) for which we don't have
a DT in the kernel tree. Keep the .dts file in the legacy U-Boot DT
directory, and let the board's defconfig opt out of OF_UPSTREAM.

Peng Fan (OSS) <[email protected]> says:
i.MX95 System Manager(SM) implements Logical Machine Management(LMM) and
CPU protocol to manage Logical Machine(LM) and CPUs(eg, M7).
To manage M7 in a separate LM or in same LM as U-Boot/Linux itself. LMM
APIs and CPU APIs are needed.
When M7 is in LM 'lm-m7', and this LM is managable by 'uboot-lm', U-Boot
could use LMM_BOOT, LMM_SHUTDOWN and etc to manage 'lm-m7'.
If in same LM, use CPU_START, CPU_STOP, CPU_RESET_VECTOR_SET and etc to
manage M7.
Both LMM/CPU APIs will be used by remoteproc driver.
