Sorry, but I read this 4-5 times and still have no idea what it means, or how it relates to this patch. [Lesly] All other sequence are getting over written by sleep seq. Because twl4030_config_sleep_sequence() function is getting called always when we enter load_twl4030_script(). And it will also over write the starting address of all seq with 0x2F. > Removed the warning print with checking order of scripts, since the order > is not important. OK, this much I get, and see what the patch is doing. > Only the values configured in the register, which is pointing to > the starting address of each sequence should be correct. aw, bummer. -ECONFUSED again Please fix the changelog to not only summarize *what* is being changed, but *why*. [Lesly] Why the order is not important. Since each seq is independent and not falling trough any other seq. Only thing we have to do is program the start address of each seq correctly.
