PCIe1 and usb_drd1_dwc3 is sharing the same PHY on RK3576 platform.
For pcie1 slot and USB interface, there is a swich IC labelled as
Dial_Switch_1 on evb1 board. If we need to make pcie1 slot work for this
board, we should first disable usb_drd1_dwc3 and then set Dial_Switch_1
to low state.

This adds support for the video-demo-adapter DEVKIT ADDON CAM-TS-A01
(https://embedded.cherry.de/product/development-kit/) for the Haikou
devkit with Tiger RK3588 SoM.
The Video Demo adapter is an adapter connected to the fake PCIe slot
labeled "Video Connector" on the Haikou devkit.
It's main feature is a Leadtek DSI-display with touchscreen and a camera
(that is not supported yet). To drive these components a number of
additional regulators are grouped on the adapter as well as a PCA9670
gpio-expander to provide the needed additional gpio-lines.

Add the necessary DT changes to enable eDP0 on RK3588S EVB1 board:
- Set pinctrl of pwm12 for backlight
- Enable edp0/hdptxphy0/vp2
- Assign the parent of DCLK_VOP2_SRC to PLL_V0PLL
- Add aux-bus/panel nodes
For RK3588, the PLL_V0PLL is specifically designed for the VOP2. This
means the clock rate of PLL_V0PLL can be adjusted according to the dclk
rate of relevant VP. It is typically assigned as the dclk source of a
specific VP when the clock of relevant display mode is unusual, such as
the eDP panel 'lg,lp079qx1-sp0v' paired with RK3588S EVB1, which has a
clock rate of 202.02MHz.
Additionally, the 'force-hpd' is set for edp0 because the HPD pin on the
panel side is not connected to the eDP HPD pin on the SoC side according
to the RK3588S EVB1 hardware design.

... and don't error out so hard on missing module descriptions.
Before commit 6c6c1fc09d ("modpost: require a MODULE_DESCRIPTION()")
we used to warn about missing module descriptions, but only when
building with extra warnigns (ie 'W=1').
After that commit the warning became an unconditional hard error.
And it turns out not all modules have been converted despite the claims
to the contrary. As reported by Damian Tometzki, the slub KUnit test
didn't have a module description, and apparently nobody ever really
noticed.
The reason nobody noticed seems to be that the slub KUnit tests get
disabled by SLUB_TINY, which also ends up disabling a lot of other code,
both in tests and in slub itself. And so anybody doing full build tests
didn't actually see this failre.
So let's disable SLUB_TINY for build-only tests, since it clearly ends
up limiting build coverage. Also turn the missing module descriptions
error back into a warning, but let's keep it around for non-'W=1'
builds.

On systems with >= 1024 cpus (in my case 1152), turbostat fails with the error output:
"turbostat: /sys/fs/cgroup/cpuset.cpus.effective: cpu str malformat 0-1151"
A similar error appears with the use of turbostat --cpu when the inputted cpu
range contains a cpu number >= 1024:
# turbostat -c 1100-1151
"--cpu 1100-1151" malformed
...
Both errors are caused by parse_cpu_str() reaching its limit of CPU_SUBSET_MAXCPUS.
It's a good idea to limit the maximum cpu number being parsed, but 1024 is too low.
For a small increase in compute and allocated memory, increasing CPU_SUBSET_MAXCPUS
brings support for parsing cpu numbers >= 1024.
Increase CPU_SUBSET_MAXCPUS to 8192, a common setting for CONFIG_NR_CPUS on x86_64.
