v1->v2:
* Trivial tweak - Move PLL
This patch corrects display clocks for i.MX8qxp DC0 subsystem by
calling imx_clk_scu2() to register them, instead of calling
imx_clk_scu(). The reason is that the clocks can source from
various parents. The clock source selection is controlled by
Distributed Slave System Controller(DSC).
This patch adds some SCU clocks support for i.MX8qxp MIPI-LVDS subsystems.

This patch set adds some SCU clocks support for i.MX8qxp DC0/MIPI-LVDS
subsystems.
With this patch set, some basic clocks for i.MX8qxp LVDS displays can be got
by drivers.

* Drop LPCG clocks as they can be registered directly in an in-tree new
DT binding way.
* Add DC0 bypass clocks
DRC events can happen virtually at anytime, including when we are

Introduce a static branch that would be set during boot if the OS
happens to be a KVM guest. Subsequent checks to see if we are on KVM
will rely on this static branch. This static branch would be used in
vcpu_is_preempted in a subsequent patch.

If its a shared lpar but not a KVM guest, then see if the vCPU is
related to the calling vCPU. On PowerVM, only cores can be preempted.
So if one vCPU is a non-preempted state, we can decipher that all other
vCPUs sharing the same core are in non-preempted state.

This change adds vbus_vsafe0v which when set, makes TCPM
query for VSAFE0V by assigning the tcpc.is_vbus_vsafe0v callback.
Also enables ALERT.ExtendedStatus which is triggered when

Reading synci_step by using rdhwr instruction may return zero if no cache
need be synchronized. On the one hand, to make sure all load operation and
store operation finished we do __sync() for every platform. On the other
hand, some platform need operate synci one time although step is zero.

This patch series adds support for UCI driver. UCI driver enables userspace
clients to communicate to external MHI devices like modem and WLAN. UCI driver
probe creates standard character device file nodes for userspace clients to
perform open, read, write, poll and release file operations. These
Introduce mhi_get_free_desc_count() API to return number
of TREs available to queue buffer. MHI clients can use this
API to know before hand if ring is full without calling queue
API.

Currently this macro is defined in internal MHI header as
a TRE length mask. Moving it to external header allows MHI
client drivers to set this upper bound for the transmit
buffer size.

Once kobject_init_and_add() failed, pci_slot_release() is called to
delete slot->list from parent->slots. But slot->list is intialized
afterwards, so we ran into the following crash:
Unable to handle kernel NULL pointer dereference at virtual address
