Base on dfi result, we do ddr frequency scaling, register
dmc driver to devfreq framework, and use simple-ondemand
policy.

arm-trust-firmware. We add a special clock-type to handle that.

Several host bridge drivers iterate through the list of bridge windows to
request resources. Several others don't request the window resources at
all.
Add a devm_request_pci_bus_resources() interface to make it easier for
drivers to request all the window resources. Export to GPL modules (from
Arnd Bergmann <arnd@arndb.de>).

1. modify clock-names, according to Heiko's suggestion, clock names
should always be in the scope of the device block (named after what
it supplies), and clock-names are always meant from the perspective
of the individual ip-block.
2. remove unnecessary clocks, refer to rk3399 TRM, aclk_usb3 is the
parent of aclk_usb3otg0/1 and aclk_usb3_grf, and we will enable
aclk_usb3otg0/1 and aclk_usb3_grf, so don't need to enable aclk_usb3
again. In addition, the aclk_usb3_rksoc_axi_perf clk is used for usb3
performance monitor module which we don't use now, so don't need to
enable it.

When do Rx compliance test, PHY is in loopback mode, we
observed that Rx test failed with long cable, and it was
found that equalizer adaptation is not happening properly.
With rx_eq_training forced from PMA, the equalizer adaptation
working fine and Rx test can pass. The root cause is that
the Rx REE component will be turned off when control data
is being received by default PHY configuration. So we need
to unmask REE control data by setting REE control data mask
register, and with this patch, equalizer training will happen
based on the signal coming from controller only.
