PWM channels that are configured to support Variable Frequency Mode
generate a signal of fixed duty cycle (50%) and variable frequency. In
such cases, the desired frequency setting is calculated differently
internally, according to a new formula.

Certain MHI clients rely on MHI host driver to queue buffers for
them. Sizes for those buffers are in turn obtained from the
controller configuration. Update the buf_len to 32K so as to
satisfy memory requirements and constraints for those clients.

Virtual buffer objects are memory constructs that occupy a large GPU
virtual memory footprint with a sparse list of physical backing memory.
The classic use case is for a large mipmapped texture with
multiple levels that can be backed in physical memory in stages as the
application requires but the usefulness of this feature goes far behind
textures.
New VBOs can be created by specifying a flag to the memory allocation
function and other objects can be bound into the object with the new
KGSL_IOCTL_GPUMEM_BIND_RANGES ioctl.
A list of all the active vbos and mappings for a process can be found
in /sys/kernel/debug/proc/<pid>/vbos.

Currently IPC logging is enabled for debug build only,so it is
very difficult to analyze the UART issue if IPC logging is
not present. To overcome this issue we have added the support of
ftrace logging. Here we have created the different events to print
the logs for different types using TRACE_EVENT macro. The ftrace
output will be present in the below path,
cat /sys/kernel/tracing/instances/hsuart/trace.

While requesting 4LN DP, the XHCI stack is removed, and re-added.
During this transition, the DWC3 core and DWC3 MSM are forced into
runtime suspend. When the DWC3 DRD receives the role switch event to
go back into host mode, it has to first bring the DWC3 core out of RPM
suspend. During RPM resume, the dwc3_core_init() API is executed,
however, it will fail as the SSPHY is not initialized (due to 4LN DP)
and the PIPE clk is not generated. For supporting HS only PHY, we
need to set the CLK MUX accordingly to use the UTMI clk.

Implement the map_pages() callback for the ARM SMMU
driver, to allow a range of physically contiguous pages of the
same size to be mapped in one call, as opposed to mapping
each page per call. Also, remove the map IOMMU driver hook,
as it is no longer used.

Modules installing perf events need to have CAP_SYS_ADMIN

module to first stage solves the problem by ensuring that
init thread insmods this module.
