The SYSCON driver was designed for using memory areas (registers)
that are used in several subsystems. We can use bits in one
register for various purposes and thus should be handled by
various kernel subsystems.
In Rockchip RK3328, the output only GPIO_MUTE pin, originally for
codec mute control, can also be used for general purpose. It is
manipulated by the GRF_SOC_CON10 register in GRF. Aside from the
GPIO_MUTE pin, the HDMI pins can also be set in the same way.
Therefore, we need to enable this feature in rockchip_defconfig.

It will be more safer for regulator consumer devices to power on
after their power suppliers are stable. And regulator consumer devices
need to completely shut down, then power up for a reset cycle.
Therefor, regulator providers need to be make sure shutdown completely.
- startup-delay-us can be used to wait regulator providers be powered on
good, according their power-up time.
- off-on-delay-us can be used to wait regulator providers be shut down
completely.

Avoid extra 120ms delay during system resume.
The xHC controller may signal wake up to 120ms before showing which usb
device caused the wake on the xHC port registers.
The xhci driver therefore checks for port activity up to 120ms during
resume, making sure that the hub driver can see the port change, and
won't immediately runtime suspend back due to no port activity.
This is however only needed for runtime resume as system resume will
resume all child hubs and other child usb devices anyway.

the TF card. Therefore, it is necessary to increase the

Kernel halt in ehci_bus_resume when read the intr_enable
register of the ehci controller. It's because that the
ehci controllers depend on the aclk_usb which only be
managed by DWC3 controller driver right now.
The clock dependency when access ehci/ohci controller registers:
CPU -> hclk_vo1usbtop -> aclk_usb -> hclk_usb -> ehci/ohci
