7f3de8336f drm/i915: Align intel_dsi*.c files a bit
I'm not really that insisting on checkpath compliance, but ragged
function paramter alignment does get me. Please adjust your editor to
just do this for you.

Ensure that the DSI packets for a particular sequence are completely
sent before going ahead in the enabling or disabling of the panel

a799a9780e drm/i915/vlv: DPI FIFO empty check is not needed
While sending DPI SHUTDOWN command, we cannot wait for FIFO empty as
pipes are not disabled at that time. In case of MIPI we disable port
first and send SHUTDOWN command while pipe is still running and FIFOs
will not be empty, causing spurious error log

e1047028e2 drm/i915: Send DPI command explicitely in LP mode
Though HS mode also should work.

v2: Change parameter as "bool hs" as suggested by Jani

3e33a84081 drm/i915/dsi: s/size_t/int/
This fixes a printf warn from gcc:

drivers/gpu/drm/i915/intel_dsi_cmd.c: In function ‘dsi_vc_send_long’:
drivers/gpu/drm/i915/intel_dsi_cmd.c:181:2: warning: format ‘%x’ expects argument of type ‘unsigned int’, but argument 7 has type ‘size_t’ [-Wformat=]

69c05eb2d8 drm/i915: add MIPI DSI command sending routines
v2: Rebase due to register bit definition change.

v3: Mostly based on Ville's review comments.
 - Use size_t for length all around.
 - Reuse dsi_vc_send_short in dsi_vc_send_long.
 - Remove stale/incorrect comments.
 - Reverse special packet sent interrupt check.
 - Use DSI controller regs for reading, not adapter.
