NCT6776 global registers 0x1c=0 and 0x24=0x5c on ASRock Extreme4

[Mike Campin <lm_sensors@xxxxxxxxxxxxxxxxxxx>]

Hi,

Only 2 of the 5 fans are showing up on my ASRock P67 Extreme4 motherboard.
It due to the NCT6776 global configuration register 0x1c and 0x24 values.
The fans work if I modify these registers prior to loading the w83627ehf
driver.

My question is where are these registers initialized? Should I ask ASRock
to fix the BIOS?

  isadump -y -k 0x87,0x87 0x2e 0x2f

          0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
     00: ff ff 00 ff ff ff ff 02 ff ff ff ff ff ff ff ff 
     10: ff ff ff ff ff ff ff ff ff ff f8 0e 00 00 ff ff 
     20: c3 33 ff 00 5c 00 00 98 00 ff 20 00 80 00 00 01 
     30: 00 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff 

  isaset -y -f 0x2e 0x87
  isaset -y -f 0x2e 0x87
  isaset -y 0x2e 0x2f 0x1c 0x3
  isaset -y 0x2e 0x2f 0x24 0x1c

Thanks, Mike
