-Clients not having WRITE_OFTEN or READ_OFTEN are uncached.
-Invalidate cache on lock only if CPU needs to read and there
are non-CPU writers in system (camera,gpu etc)
-Flush cache on unlock only if CPU writes. Since all buffers will be
read in HWC(MDP) there is no need to check if readers exist.

Remove opaque types like size_t, uintptr_t, intptr_t to support
32bit and 64bit processes together.
When a 64bit process creates a handle and a 32bit process validates
the incoming ints against expected ints, opaque types lead to
different and mismatching values.
Always use unit64_t for base address for 32bit and 64bit SF.
Use unsigned int for offset and size, since ION uses that.

The android_ycbcr structure in graphics.h is populated to give
the luma and chroma addresses. Use the same structure to give
this information to graphics via a gralloc perform call.

* Provide a binder interface call for wfd module
to inform display about the start/stop/pause/resume
of wfd session.
* This is needed for wfd-hdmi synchronization in
case of v4l2 wfd solution. If hdmi is plugged
in during v4l2 wfd session, display-hal waits in
uevent thread for wfd teardown notification from
wfd module, before going ahead with configuring
external display.
* For VDS WFD solution, display-hal waits in uevent
thread for wfd-teardown to be signalled from
the composition thread.

Macro tile is enabled only if all the conditions are met:
1. GPU hardware should support Macro Tiling.
2. MDSS hardware should support Macro Tiling.
3. USAGE flags shouldnt contain GRALLOC_USAGE_SW_READ_OFTEN and
GRALLOC_USAGE_SW_WRITE_OFTEN.
4. RGB 16bit and 32bit formats.
5. persist.hwc.macro_tile_enable flag should be enabled.
PRIV_FLAGS_TILE_RENDERED flag is added to indicate whether the layer
is rendered/composited in Macro Tiling or Linear format.

Use new GFX API compute_aligned_width_and_height to get the stride
value for RGB surfaces.
Backward compatible with GFX old API when old GFX library is used.

libadreno_utils.so is an adreno utility library. It computes the
optimal stride required for a surface of a particular width and
bpp. Using this computed stride allows us to efficiently use the
dual memory channels and increase performance.
Currently the utility library only computes the optimal stride
for RGB surfaces.

- Introduce a new class to Get the Adreno computed stride information.
This class has been added to allow adreno library computed strides to
be propagated to the allocation function as well as those clients
requesting it.
- Add a new Perform function to get the stride. The width and the format
can be passed from the calling functions (like EGL) to get the stride of
the buffer.
