Make VBIF register dump more generic to avoid adding new entry
for every VBIF revision. There will not be any change in register
mapping and address for new VBIF revision. AHB reads are permitted
throughout entire VBIF range. For all unoccupied registers read
values driven to 0 by HW but should not be relied upon.

For A3xx we get GPU read pointer from the CP_RB_RPTR
register instead of rptr scratch memory address. In
retire_cmdbatch() and _retier_maraker() GPU clock will
be off, so avoid reading CP_RB_RPTR register. Also hold
device mutex in sendcmd() to access GPU registers.

Check the return value of dma_buf_get function using
IS_ERR_OR_NULL as dma_buf_get function can return
ERR_PTR(-EINVAL) which won't be caught by simple NULL
check. This will avoid kernel panic due to invalid
pointer access.

Dump 256 instead of 128 dwords of SDS as DRAW_STATE_ADDR is
actually 8 bits wide [7:0] and not 7 bits wide [6:0].

A540 has a new vbif version. Add it so that we can
dump vbif registers in snapshot for A540.

This is done to improve the kgsl vmfault routine. Currently,
it traverses the sglist to find the faulted page, which takes
linear time. By having an array of all the page pointers,
this operation will be completed in constant time.
Also, allocate sgt only for mapping this memory to the GPU.
Since this optimization is not needed for secure/global or
imported memory, we will not keep this array but keep
the sgt instead.

This change adds a check to avoid allocating memory for loading microcode
in case it is already allocated. This avoids memory allocation failure
for microcode during multiple tries by userspace to open the kgsl device
in case of errors.

Tracks GPU active time per frequency for GPU workload
profiling. The data will be output in
/sys/class/kgsl/kgsl-3d0/gpu_clock_stats
with one u64 value in microseconds per clock level.

This reverts commit <a67208e94d945ad890f8dc4734ec5fdb3219cc03>.
This commit prevented xo shutdown as during suspend exit, WSA sensor for
temperature read triggered a slimbus wakeup. Slimbus suspend mechanism
will expect a qmi message after the system has entered suspend. This
will wake the system from suspend. This happens recursively and
system will never enter suspend.
Revert this commit to avoid this issue, till the slimbus suspend
mechanism is fixed.

The array index value when setting/getting the channels
of proxy is incorrect as the channel count begins from two.
Fix by setting the correct index offset.
