The xHCI specification 1.1 does not require xHCI-compliant
controllers to always enable hardware USB2 LPM. However,
the current xHCI driver always enable it when seeing HLC=1.
On rv1106 platforms, the xHCI USB2 LPM is enabled by default.
And we found that a lot of USB Disks have USB2 HW LPM broken
issue when connected to rv1106 USB2 OTG interface.
Here are a part of special USB Disks with USB2 HW LPM broken:
1. idVendor=325d, idProduct=6410, Manufacturer: aigo
2. idVendor=21c4, idProduct=0cd1, Manufacturer: Lexar
3. idVendor=0951, idProduct=1666, Manufacturer: Kingston
When use dd command to write to these USB Disks, it may fail
with the following log:
[ 2844.700148] usb 7-1: reset high-speed USB device number 4 using xhci-hcd
[ 2889.072272] usb 7-1: reset high-speed USB device number 4 using xhci-hcd
[ 2921.498045] usb 7-1: reset high-speed USB device number 4 using xhci-hcd
......
[ 2953.923773] usb 7-1: reset high-speed USB device number 4 using xhci-hcd
Theoretically, we can add USB_QUIRK_NO_LPM individually for
these special USB Disks, however, it's difficult to cover all
USB Disks. So it's better to disable the USB2 LPM for xHCI
on rv1126 platforms.

Add the clock tree definition for the new RK3528 SoC.
gmac1 clocks are all controlled by GRF, but CRU helps to abstract
these two clocks for gmac1 since the clock source is from CRU.
The io-in clocks are module phy output clock, gating child
clocks by disabling phy output but not CRU gate.
Add gmac0 clocks.
They are all orphans if clk_gmac0_io_i is not registered by
GMAC driver. But it's fine that GMAC driver only get it but
not to set/get rate.
Add CLK_SET_RATE_PARENT for mclk_sai_i2s0/1.
Allowed to change parent rate.
Add CLK_SET_RATE_NO_REPARENT for dclk_vop0.
dclk_vop0 is often used for HDMI, it prefers parent clock from
clk_hdmiphy_pixel_io for better clock quality and any rate.
It assigns clk_hdmiphy_pixel_io as parent in dts and hope not to
change parent any more.
Add CLK_SET_RATE_PARENT for aclk_gpu.
Allow aclk_gpu and aclk_gpu_mali to change parent rate.
Add CLK_SET_RATE_PARENT for aclk_rkvdec_pvtmux_root.
Allow aclk_rkvdec_pvtmux_root and aclk_rkvdec to change parent rate.
set aclk_m_core = core_clk/2.
aclk_m_core signoff is 550M, but we set div=2 for better
performance.
Add CLK_IS_CRITICAL for clk_32k.
Mainly for pvtpll during reboot stage.
Add CLK_IS_CRITICAL for all IOC clocks.
IOC doesn't share clock with GRF. The iomux can't be changed if they
are disabled.
Disable aclk_{vpu,vpu_l,vo}_root rate change
They are all shared by multiple modules, disable rate change
by modules.
Don't register clk_uart_jtag
It's for force jtag uart delay counter. It must be open
for box product without tf card but with uart0.

The dwc2 driver use the nak interrupt for the starting point
of isoc-in transfer. The first nak interrupt for isoc-in means
that in token has arrived and the dwc2 driver can obtain the
(micro) frame of the token to set the even/odd (micro) frame
field of DIEPCTL.
However, on some platforms (e.g Rockchip rk3308) which don't
support the "OTG_MULTI_PROC_INTRPT", it means that all device
endpoints share the same nak mask and interrupt. If the nak
interrupt is always enabled, it may trigger nak interrupt storm
by other endpoints except the isoc-in endpoint. So we disable
the nak interrupt when get first isoc in token if the feature
"OTG_MULTI_PROC_INTRPT" isn't enabled.
