The sdmmc node already have a "&sdmmc_det" for pinctrl which switch the
GPIO0A4 to sdmmc detect function, no need to define a separate "cd-gpios".
RK3588 has force_jtage feature which is enable JTAG function via sdmmc
pins automatically when there is no SD card insert, this feature will
need the GPIO0A4 works in sdmmc_det function like other mmc signal instead
of GPIO function, or else the force_jtag can not auto be disabled when
SD card insert.

A hardware switch can set the rs485 transceiver into half or full duplex
mode.
Switching to the half-duplex mode requires the user to enable em485 on
uart5 using ioctl, DE/RE are both connected to GPIO0_B5 which is the
RTS signal for uart0. Implement GPIO0_B5 as rts-gpios with RTS_ON_SEND
option enabled (default) so that driver mode gets enabled while sending
(RTS high) and receiver mode gets enabled while not sending (RTS low).
In full-duplex mode (em485 is disabled), DE is connected to GPIO0_B5 and
RE is grounded (enabled). Since GPIO0_B5 is implemented as rts-gpios, the
driver mode gets enabled whenever we want to send something and RE is not
affected (always enabled) in this case by the state of RTS.

Add support for the Powkiddy RGB10MAX3. The Powkiddy RGB10MAX3 is a
handheld gaming device with a 720p 5.0 inch screen powered by the
Rockchip RK3566 SoC. It includes a Realtek 8723ds WiFi/BT module, 2 ADC
joysticks powered by a 4-way muxed ADC channel, and several GPIO
face buttons. There are 2 SDMMC slots (sdmmc1 and sdmmc3), 3 pwm
controlled LEDs, and the device includes 1GB of RAM.

Move the vdd_cpu regulator to the device specific dts. This is in
preparation of adding the Powkiddy RGB10MAX3 device, which uses
a different vendor for the CPU regulator at a different i2c address.
Also add a phandle to the bluetooth device so that we can change the
compatible string for the RGB10MAX3. This device uses the same pinouts
but a different bluetooth device.

Add missing cache information to the Rockchip RK3399 SoC dtsi. The specified
values were derived by hand from the cache size specifications available from
the RK3399 datasheet; for future reference, here's a brief summary:
- Each Cortex-A72 core has 48 KB of L1 instruction cache and
32 KB of L1 data cache available, four-way set associative
- Each Cortex-A53 core core has 32 KB of instruction cache and
32 KB of L1 data cache available, four-way set associative
- The big (A72) cluster has 1 MB of unified L2 cache available
- The little (A53) cluster has 512 KB of unified L2 cache available
This patch allows /proc/cpuinfo and lscpu(1) to display proper RK3399 cache
information, and it eliminates the following error in the kernel log:
cacheinfo: Unable to detect cache hierarchy for CPU 0
While there, add a couple of somewhat useful comments, which may help a bit
anyone going through the RK3399 SoC dtsi.

By default the GPIO pin that connects to the WiFi enable signal
inside the M.2 Key E slot is driven low, resulting in impossibility
to connect to any network. Add a DT node to expose it as an RFKILL
device, which lets the WiFi driver or userspace toggle it as
required.

The NanoPC-T6 has a Mini PCIe slot intended to be used for a 4G or LTE
modem. This slot has no PCIe functionality, only USB 2.0 pins are wired
to the SoC, and USIM pins are wired to a SIM card slot on the board.
Define the 3.3v supply for the slot so it can be used.

Two pmuio domains on ringneck are not defined:
1- PMUIO1: supplied by vcc_3v3 regulator(PMIC RK809)
2- PMUIO2: supplied by vcc_3v3 regulator(PMIC RK809)
The reason why no functional effect was observed is because of that
the above mentionned PMUIO domains were supplied by a regulator
which is always on.
So let's add their definition in the dtsi.

Pull more bcachefs updates from Kent Overstreet:
"Some fixes, Some refactoring, some minor features:
- Assorted prep work for disk space accounting rewrite
- BTREE_TRIGGER_ATOMIC: after combining our trigger callbacks, this
makes our trigger context more explicit
- A few fixes to avoid excessive transaction restarts on
multithreaded workloads: fstests (in addition to ktest tests) are
now checking slowpath counters, and that's shaking out a few bugs
- Assorted tracepoint improvements
- Starting to break up bcachefs_format.h and move on disk types so
they're with the code they belong to; this will make room to start
documenting the on disk format better.
- A few minor fixes"
