Browse source

[ Upstream commit aa86602a48 ]

Move the configuration of the Auto-Hibern8 (AHIT) timer from the
post-link stage to the 'fixup_dev_quirks' function. This change allows
setting the AHIT based on the vendor requirements:

   (a) Samsung: 3.5 ms
   (b) Micron: 2 ms
   (c) Others: 1 ms

Additionally, the clock gating timer is adjusted based on the AHIT
scale, with a maximum setting of 10 ms. This ensures that the clock
gating delay is appropriately configured to match the AHIT settings.
