If minidump is not enabled, minidump add region api returns
error number, clients can log the error to log buffer, which
flood the log buffer unnecessarily.
So return quietly if minidump support is not enabled.

Add support for hardware that can switch both parent clocks and divider
at the same time. This avoids generating intermediate frequencies from
either the old parent clock and new divider or new parent clock and
old divider combinations.

avoid blocking other interrupts and reduce latencies in

Also keep error check for BAM rx completion.

This file seems to have a BOM sequence to indicate the file is
UTF-8. There aren't any UTF sequences in the file though, and
this trips up sparse when running on files that include this
header. Remove the BOM so sparse is happy.

Current DRM adds offset when making IOVA but failed to add it when

Currently power Delivery (PD) is enabled by default which sends
PD Hard reset in SINK mode to negogiate PD contract with host machine
after connect, if no capabilities message is received from other device.
This impacts with compliance for example: PMI ignores type-c disconnects
during PD Hard Reset. Add module parameter to disable PD so that it
doesn't enable PD communication during USB3.1 compliance testing.

While executing tuning in case CMD19 fails, the driver sends CMD13
multiple times to ensure the card is ready to receive the next tuning
command. If this status command fails with CRC error, it will trigger
tuning. This will result in back to back tuning multiple times.
To avoid this situation, ignore CRCs error generated with CMD13 while
executing tuning.

Provide complete resolution details in a sysfs node "res_info"
limited to PAGE_SIZE. Different modules can query for multiple
resolution details based on the resolution ids received from
EDID of the TV. In case resolution details exceed PAGE_SIZE,
reuse res_info to get remaining timing details by provide page
details. Check page id is within the max supported resolution
ids to avoid reading extra memory than required.

There is no validation of the "count" parameter, which is controlled
by the user and used as a size of allocated memory. If the user
provides a value of "0" for "count", then kmalloc would not return
NULL, but also there will be a memory block of "zero" size. This can
lead to buffer overflows. Also trying to access invalid memory will
cause kernel crashes. Ensure to check that the number of bytes to be
written is non-zero. If zero, return invalid input.
