There is a bt power issue on Debian OS, the blueman app
will callback to enable the bluetooth power during the bringup.
As below log the system bringup about 10s.
[BT_RFKILL]: rfkill_rk_set_power: set bt wake_host pin output high!
[BT_RFKILL]: rfkill_rk_set_power: enable bt reset pin!
[BT_RFKILL]: ENABLE UART_RTS
[BT_RFKILL]: DISABLE UART_RTS
[BT_RFKILL]: bt turn on power
...
So the rfkill-bt driver should judge the power status, otherwise the
blueman app will cause the bluetoolth timeout error. e.g:
root@linaro-alip:/# bluetoothctl
[NEW] Controller 3B:A0:90:48:46:40 linaro-alip [default]

Commit 5d425c1865 ("arm64: kernel: add support for cpu cache
information") adds cacheinfo support for ARM64. Since there's no
architectural way of detecting the cpus that share particular cache,
device tree can be used and the core cacheinfo already supports the
same.
This patch adds the l2 cache topology on RK3308 SoC based boards.

The commit e6f2f6d63e ("usb: dwc2: power on/off phy for
otg mode") aimed to control phy power for otg mode, but
it also introduced a new problem, so we fix it.
This patch keep phy power on for otg if current mode is
host during dwc2 probe, otherwise the enumeration will
fail with the following error log:
Cannot enable. Maybe the USB cable is bad?
Cannot enable. Maybe the USB cable is bad?
attempt power cycle
Cannot enable. Maybe the USB cable is bad?
Cannot enable. Maybe the USB cable is bad?

Three operating mode are available to convey the graphical data
to the display:
- Video mode streams over the high-speed link the RGB data and the
associated synchronization signals directly generated by the LCDC.
The streaming starts as soon as the DSI Host and the LCDC are enabled.
This continuous refresh is the best way to interface with a display
without Graphics RAM.
- APB command mode sends commands over the high-speed link for
configuration as it is done using a legacy serial interface (SPI).
The commands are launched using the DSI Host APB interface.
- Adapted command mode is the best way to interface with a display
having its own internal Graphics RAM. The DSI Host captures only
one full frame coming from the LCDC and transforms it into a series
of write commands to update the display Graphics RAM.

Because the .bind() function might call multiple times, so it is
