The DMA buffers used by the display module are cached buffers. While
mapping to the CPU, pgprot_writecombine should only be used for uncached
buffers. The change fixes this mismatch during virtual address mapping.

Some panels may require that the DSI link returns to the low-power
stop state (LP11) after transmission of every line. If a panel
requires that the DSI link returns to LP11, apply the LP11
insertion between lines feature.
This change adds support to
- Disable the command mdp burst mode
- Enable mdp idle ctrl
- Program the No. of dsi pclk cycles of idle time to
insert between command mode mdp packets. The idle time
must be long enough to cover the time link takes to
switch between HS to LP11 mode.

During idle power collapse, dim layer dirty flags are
stored in sde_crtc_state which might be invalid if state
swap occurs. This change adds revalidate mask in sde_crtc
structure to revalidate after coming out of idle power
collapse.

This change avoids upstream drm issuing drm_atomic_commit in
drm_fb_release which is leading to artifacts on screen or
atomic_check failures due to atomically unstaging each fb
from plane_state and committing remaining planes on hardware.
a) This patch moves the state operations for setting crtc to
connector state to a helper api.
b) This patch clears any dim_layers present in the crtc_state
as part of null commit.
c) This patch removes any framebuffers attached to a drm_file
in msm_preclose whose refcount is not managed by composer kill
inadvertently and issues null flush to hardware in such cases.
d) This patch handles msm_preclose as part of msm_release
operation since legacy feature is not supported
for msm_driver.

The connector detect function is currently implemented as a
callback from the framework, and creates a context before
calling the detect_port_ctx MST callback. This change updates
the callflow so that the framework calls the new detect_ctx
function in the MST case. This removes the need for creating a
new context before calling further downstream functions.
In addition, references to the mst_connector_get_info
function were replaced by connector_get_info to avoid
redundancy.
