1.
schedule_delayed_work(&pcd->check_id_work,msecs_to_jiffies(HZ))
should be schedule_delayed_work(&pcd->check_id_work,HZ)
2.fix coding-style to pass checkpatch.pl
3.set otg controler working on foece host/device mode to avoid
mode_missmatch_interrupts
If same layer is closed twice, atv_layer_cnt may be
set to zero, so vop go to standy. Now win0、win1、hwc
is mapped to atv_layer_cnt bit[0-2]. When open/close
layer, set coresponding atv_layer_cnt bit to one/zero.
The driver supports 32 parameters of each mipi cmds
when initialization the mipi screen.
But the users may send a cmds longer the 32 parameters sometimes,
and it will result in that the array out of range.
DTYPE_GEN_SWRITE_2P:
Generic Short WRITE Packet with 2 parameters(one command
and one parameter). But the users may send the packet more
than 2 parameters.
DTYPE_GEN_SWRITE_1P:
Generic Short WRITE Packet with 1 parameters(one command
without parameter).
DTYPE_GEN_SWRITE_0P:
Generic Short WRITE Packet with 0 parameters(nop packet
without command and parameter).
Take following sequence to avoid picture flash when swiching resolution:
1. Send AV_MUTE GCP packet.
2. Power off hdmi phy.
3. Sleep 2 second to wait TV process no TMDS signal.
4. Configure video and audio registers.
5. Power on HDMI phy.
6. Send CLEAR_MUTE GCP packet.
before release fence, we should make sure extend lcdc config take
effect. if not, maybe GPU would access the buffer which hdmi using,
and cause tearing.

1. Remove ehci_port_power() in ehci-rockchip, since commit
c73cee7 the ehci_port_power() function no longer needed,
ehci hub driver taking care of power supply.
2. Fix 64-bit address pointer warnning.
3. Register rk-rhci driver by ehci_init_driver() for reducing
useless code.
4. Fix kernrl crash caused by null pointer dereference ,
When 'echo 0 > ehci_power' usb_remove_hcd() run twice. Set rk
ehci->host_enabled 0 to stop connect_detect thread.
For box, we need to set hdmi switch state when insert/remove,
regardless of whether the device supports audio. So add function
rk_fb_get_display_policy() to get display policy.
If master power domain is disabled,at this time to r/w the
iommu register,it would failed.Master call the attach_deivce
means it must power on itself,so iommu_reset in attach_device
can guarantee the safety
Depend on this, we can remove the vpu/hevc GRF relative code
