Descripted in drm_gem_object structure description:
* Reference count of this object
*
* Please use drm_gem_object_get() to acquire and drm_gem_object_put_locked()
* or drm_gem_object_put() to release a reference to a GEM
* buffer object.
*/
struct kref refcount;
It's better to release object by drm_gem_object_put.
About the refcount for object of drm device,
rockchip_gem_create_object -> refcount = 1
drm->driver->gem_prime_export -> refcount = 2
This patch will decrease a refcount from export, and decrease another
one in rockchip_drm_direct_show_free_buffer:
drm_gem_dmabuf_release -> refcount = 1
rockchip_drm_direct_show_free_buffer -> refcount = 0
Tested by rockchip_drm_self_test.c.

"struct pt_regs" is big data structure, so pass a "struct pt_regs *"

"fiq_pt_regs" is a big data structures, so it'll save
lots of stack space if define "fiq_pt_regs" as a global
variable instead of a local variable.

The MAX96745 and MAX96747 convert DP1.4 and
eDP1.4a to single or dual GMSL2 serial. They also send
and receive control channel and peripheral control data,
enabling bidirectional transmission of video and data over
cables in excess of 15 meters in length.

SC8886 will shutdown the output off in these cases
when battery was removed:
1. INPUT CRRENT is set to 0. In Battery system, battery
would take over system supply, but in no battery system,
it would restart due to system poweroff.
2. VBat is higher than VSysmin, sc8886 would switch
system supply to VBat, But in no battery system, there
is just a capacitance, the voltage of capacitance would
be pull down quickly when supply switch and it make
system restart.
