pca9547 won't probed since its status property is disabled.
while there are devices connected to it, we need remove status
property to let ds3232 and adt7461 probed correctly.

For the platforms including LS1021A, LS1043A that has the
flextimer module, implementing alarm functions within RTC
subsystem to wakeup the system when system going to sleep.
Only Ftm0 can be used to wakeup the system.

Tested those 5 patches on LS1021a-twr, and everything is fine.

Hi Stefan,
I had tested the patches on LS1021A-TWR board using drmlib.
Like set three overlays:
root@ls1021atwr:~# ./modetest -P 39:900x100+10+10@RG24 -P 39:200x200+300+0@RG24
-P 39:200x200+400+300@RG24
How did you test the overlays and cursor layer, I mean I see you using x-window
like thing

Hi Stefan,
Sorry for reply late, I was on PTO. And another PTO on June 9~11, 2016.UTC+8

I expect that regmap write as big endian, and I am seeing is regmap write as
little endian.
Thanks,

4,
.val_bits = 32,
.cache_type = REGCACHE_RBTREE,
// .reg_format_endian = REGMAP_ENDIAN_BIG,
// .val_format_endian = REGMAP_ENDIAN_BIG,
.volatile_reg = fsl_dcu_drm_is_volatile_reg,
};
Thanks,
Best Regards,

find which commit caused that.
Since I am not familiar with regmap, hope you can give me some advice.
Thanks,

t works.
But "regmap_update_bits" still have the problem.
I had checked log of regmap, and didn't find which commit caused that.
I am not familiar with regmap, can you give some advices?
Thanks,

Meng Yi
