With CONFIG_DMA_BOUNCE_UNALIGNED_KMALLOC enabled, the arm64 kernel still
allocates the default SWIOTLB buffer (64MB) even if ZONE_DMA is disabled
or all the RAM fits into this zone. However, this potentially wastes a
non-negligible amount of memory on platforms with little RAM.
Reduce the SWIOTLB size to 1MB per 1GB of RAM if only needed for
kmalloc() buffer bouncing.

- Add &spi0, &i2c4, &i2c5 for the pin-conections (all disabled)
- Remove &spi1 since it's not available on the board
- vcc_3v3_sd_s0: remove unevaluated property flasgs"enable-active-low", it's unneeded since the default assumed is Active low (linux/Documentation/devicetree/bindings/regulator/fixed-regulator.yaml)
- analog-sound: remove unevaluated property "simple-audio-card,hp-pin-name"
- &sdhci: remove "max-frequency = <200000000>;" since this value already defined as default in rk3588s.dtsi
- Rename node "button@1" to "button-user"
- Move "status" property to bottom, even if disabled
- Improve comments
One patch also fixes Combo PHY.
Many thanks goes to the geniuses Sebastian Reichel and Michal Tomek. Without their brainpower, PCIe bifurification on the RK3588, like the mode used by the CM3588, would still be broken.
Sorting the patches to group them by category:
000* for general patches
00** for SoC related patches
01** for GPU/HDMI related patches
08** for wireless patches
1*** for board patches
101* for Rock-5B, 1012* for Rock-5A and so on
BPI-CM4
No change in functionality. Fixup adjustments.
BPI-M2S
The fan on the unit is constantly running. So lets set thermal
trip points and add the ability to control when we want it to
kick on. By default it is set to power on at 60*C.

* updates from rewrite-kernel-patches
* updates from rewrite-kernel-config
rk322x has peripheral mode that is not working
really well, add various non-upstream patches
and timing adjustments that makes things a bit
more usable (mass storage and ethernet works,
uac isn't)
* meson-6.7: Copy patches from 6.6
Commit f852beca0a ("Switch meson64, bcm2711, sunxi, imx6, mvebu current to 6.6, edge to 6.7 and leave 6.1 for legecy") bump to linux 6.7 but forget to copy patches.
* meson-6.7: Refresh patches
* Add board BananaPi M4 Zero

* HACK: wrong DRAM size: add extra barrier in mctl_mem_matches
People report that this is fixed by adding another "dsb();" at
the beginning of the mctl_mem_matches() function.

- allows users to put .dts files bare in `userpatches/kernel/rk35xx-legacy/dt`
- important: everyone is still invited to send the DTs to https://github.com/armbian/linux-rockchip directly
- where yes, they'll have to patch the Makefile there as normal
* meson-s4t7: bump u-boot to khadas-vims-u-boot-2019.01-v1.6-release
* Use khadas default bootargs as much as possible
* Add new hook to allow copying code into kernel
* meson-s4t7: legacy: Switch to 5.15 kernel
* meson-s4t7: add kernel-config for 5.15 kernel
* device tree overlays for 5.15 kernel for vim1s and vim4
* restructure packaging of bsp files for vim1s/vim4
* silence vblank warning on boot
* Remove display workaround as it doesn't work with 5.15 kernel
* Remove 5.4 kernel patches
* add salvas UHS overlay and enable on 2 known devices known to have voltage regulator needed to leverage UHS
* remove increased UHS from pinebook-pro default due to justification in kernel commit history
* remove enabling YOLO UHS overlay from default board config
* rockchip64: Add board "ASUS Tinker-Edge-R"
* rockchip64: Add board "ASUS Tinker-Edge-R": hammer for 6.6 current & 6.7 edge
- cleanup
- squash dtsi and dt into a single thing, rename to dashes
- change dtb reference in board file
- drop the 6.1 patch that has junk in it

PWM controllable fan (G12A/B/SM1)
Commit provides two new overlays. One for the BananaPi CM4IO
Baseboard "GPIOH_5" and another for general use "GPIOX_5".
CM4IO HEADER PINS: 5V "4"; GND "6"; PWM "7"
On other units the location of the PWM HEADER PIN may vary,
so users will need to either review the wiki or schematic
of said unit.
Fan used in testing:
https://a.co/d/hasnLtj
Modifications: M2S/M5 RTL8822CS
Modded the overlays to be specific to the unit they were made
to be used on.
Tested-on: BananaPi BPI-CM4IO Baseboard with BPI-CM4 Module
