This patch set is to introduce lcdif support for i.MX6.

Now only i.MX6UL support is in this patchset.
Patchset tested on mx6ul_14x14_evk and mx6ul_9x9_evk
(needs 9x9 SPL patch applied).

1/11
There are two LCD interface for i.MX6SX and one interface for i.MX6UL,
so change the prototype mxs_set_lcdclk to handle different interface.

[2,3]/11
I am not sure, but from my understanding, the 'board_' should be discarded.

4/11
mx28 and mx6ul/sx have similar register layout and bit definitions, so
move related structure and bit definitions to imx-common.

[5,6,7]/11
is to add related CCM macros, clock apis for enable lcdif on i.MX6

8/11
support lcdif for i.MX6UL 14x14/9x9 board

9/11
Introduce lcdif_power_down, to make system stable when reset or boot os

[10,11]/11
Need to call lcdif_power_down, before trigger wdog reset or boot os.
Or we may met unexpected system hang.

Peng Fan (11):
  mxs: add parameter base_addr for mxs_set_lcdclk
  sandisk: sfp: correct function name
  xfi3: correct function name
  imx: imx-common: move lcdif structure and macro definition to
    imx-common
  imx: mx6: fix register address
  imx: mx6: crm_reg: add LCDIF related macros
  imx: mx6: add clock api for lcdif
  imx: mx6ul_14x14_evk: support lcdif display
  video: mxsfb: introduce lcdif_power_down
  imx: mx6: implement reset_misc
  imx: imx-common: power down lcdif before boot os
