Detailed Timing Descriptors (DTDs) listed in the EDID data contain
the information about the horizontal addressable video pixels for
each resolution. The maximum value that can be specified for this
field is 4095. In certain instances, a sink may list a resolution
with 4096 horizontal addressable video pixels in the DTD by listing
a value of 4095. If this value is parsed as is, it can lead to
incorrect behavior. Fix this by explicitly updating the value to
4096.

In macro QSEECOM_ALIGN, change (x + QSEECOM_ALIGN_SIZE) to
(x + QSEECOM_ALIGN_MASK); otherwise, when x is already aligned,
QSEECOM_ALIGN(x) will get (x + QSEECOM_ALIGN_SIZE), but it should
be x. Also, remove the dulplicate QSEECOM_ALIGN definition
in hdcp.c and mpq_sdmx.c, since they already include

Adreno GPUs have a certain number of fixed performance counters
most of which can be programmed to a large number of different
items (countables). A centralized database in the kernel is
needed to make the most efficient use of counters across processes.
Add performance counter tracking and APIs to allow applications to
reserve performance counters by requesting a group ID and a countable
(countables differ from block to block). The kernel will check to
see if an active counter is already selected for that countable or
if a new one should be assigned. Different processes can share the
same counter if they both need the same countable.
Counters are reserved with DRM_IOCTL_MSM_COUNTER_GET which returns
a counter ID for the reserved counter and the hi/lo offset of
the counter register. The reserving application can either read the
counter from within a PM4 stream or it can use the group ID and
counter ID and read the value of the counter with
DRM_MSM_COUNTER_READ. After the counter is no longer needed
DRM_IOCTL_MSM_COUNTER_PUT returns it and it can be released for
other countables if no other processes are sharing it.
Reservations are tracked for each process and cleaned up if the
process dies without putting back the counters.

In current pm_qos implementation - when the new pm_qos vote request
comes, the previous cpu group where pm_qos vote was put
is determined and removed if the current cpu group is different
than previous.
If the pm_qos vote of performance mode latency is put during
initialization, there can be a case where this vote will never be
released - since during init phase we can't cache the prev pm_qos cpu
group (pm_qos_prev_cpu = -1). Thus during the actual I/O sdhci_request
the pm_qos_prev_cpu will be -1 and unless the request comes once onto
each of those cpu group, the pm_qos voting can never be released.
Hence change this pm_qos vote for all cpu groups to PM_QOS_DEFAULT_VALUE
during init phase.
