The ARM Trusted Firmware (ATF) had a configure been used by default.
As far, the rockchip_suspend can be configured in kernel when someone need

Some of the RK3399 sapphire excavator boards have a
suspend/resume issue with the following error log:
dpm_run_callback(): usb_dev_suspend+0x0/0x30 returns -16
PM: Device usb6 failed to suspend async: error -16
PM: Some devices failed to suspend, or early wake event detected
If this error happens, the USB port can't recognize
any USB device with the failed log:
usb usb5-port1: connect-debounce failed
It's because that the Type-A USB3 port which belongs
to fe900000.dwc3 is in abnormal state. We can check
the link state easily via the debug node:
cat /sys/kernel/debug/fe900000.dwc3/link_state
The normal link state is Rx.Detect if no USB device plug
in. But after resume, the link state will change to Polling.
According to the USB 3.1 Spec, the link state can change
from Rx.Detect to Polling state if the USB3 PHY detect
the far end receiver termination. From that we infer that
the USB3 PHY affects the USB3 controller link state since
the USB3 PHY is in power on state when enter suspend.
Actually, it's a common problem if the DWC3 work as Host
mode in the following cases, and it only happens if system
enter suspend/resume without any USB device conneted.
Case1. Type-A USB 3.0 interface with dr_mode = "host";
Case2. Type-A USB 3.0 interface with dr_mode = "otg",
and set DWC3 to host mode via "dwc3_mode";
Case3. Type-C USB 3.0 interface with dr_mode = "host";
Case4. Type-C USB 3.0 interface with dr_mode = "otg",
and plug in Type-C to Host cable;
Case5. Type-C USB 3.0 interface with dr_mode = "otg",
and set DWC3 to host mode via "dwc3_mode";
This patch power off the USB3 PHY if no USB device connect
with the DWC3 Host port before enter suspend, and power on
the USB3 PHY again upon resum.

The RNDIS gadget function has USB class of 2 and subclass
of 2, which matches "USB\Class_02&SubClass_02" in the
usbser.inf file in the Windows system, so the device is
initially detected as a COM port instead of RNDIS. This
is why we need to install RNDIS manually.
Refer to Defined Class Codes [1] and rndis_host of Linux [2],
this patch sets the RNDIS gadget with base class of 0xE0h
(Wireless Controller) and subclass of 0x01h and protocol
of 0x03h.

drm_dp_cec_register_connector() is called when registering each DP
connector in DRM, while sounds a good idea register CEC adapters as
earlier as possible, it causes some driver initialization delay
trying to do DPCD transactions in disconnected connectors.
This change will cause no regressions as drm_dp_cec_set_edid() will
still be called in further detection of connected connectors with a
valid edid parameter.
This change reduced the module load of i915 by average 0.5sec in a
machine with just one DP port disconnected while reducing more than
3sec in a machine with 4 DP ports disconnected.

If aux->transfer == NULL, then just return without doing
anything. In that case the function is likely called for
a non-(e)DP connector.
This never happened for the i915 driver, but the nouveau and amdgpu
drivers need this check.
The alternative would be to add this check in those drivers before
every drm_dp_cec call, but it makes sense to check it in the
drm_dp_cec functions to prevent a kernel oops.
