To classify errors:
RX/TX error count < 128 is CAN_STATE_ERROR_WARNING,
An error frame is sent, enters the active error state.
RX/TX error count < 256 is CAN_STATE_ERROR_PASSIVE,
An error frame is sent, enter passive error state.
RX/TX error count >= 256 is CAN_STATE_BUS_OFF,
can bus off need to restart.

This reverts commit 6b7fb9a6c9.
The audio regbank of hdmi-qp is drived by audio interface clk, and had
fixed by commits as follows:
[1] 3a7f369b5c ("arm64: dts: rockchip: rk3588: Add aud clk for hdmi nodes")
[2] e108ff9f6f ("drm/rockchip: dw_hdmi: Handle aud clk for hdmi qp")
OTOH, to make android hal happy, we still allow to access hdmi audio even
hdmi is plugged out.
"hdmi-audio-codec: ASoC: error at snd_soc_dai_startup on i2s-hifi: -19"
Android/Linux should reopen hdmi sound card depends on HPD plug event
to bring back to normal state.

The separation of pinctrl and gpio drivers created a tiny window where
a pinconfig setting might produce a null-pointer dereference.
The affected device were rk3288-veyron devices in this case.
Pinctrl-hogs are claimed when the pinctrl driver is registered,
at which point their pinconfig settings will be applied.
At this time the now separate gpio devices will not have been created
yet and the matching driver won't have probed yet, making the gpio->foo()
call run into a null-ptr.
As probing is not really guaranteed to have been completed at a specific
time, introduce a queue that can hold the output settings until the gpio
driver has probed and will (in a separate patch) fetch the elements
of the list.
We expect the gpio driver to empty the list, but will nevertheless empty
it ourself on remove if that didn't happen.
