The differences are small between the 3.13 ones
- DPLL_A_MD: 0x04c75adf
+ DPLL_A_MD: 0x0c875a9f
- DPLL_B: 0x04c75adf (disabled, non-dvo, VGA, TV B/C
cloc
k, DAC/serial mode, p1 = 1, p2 = 10)
+ DPLL_B: 0x0c875a9f (disabled, non-dvo, VGA, TV B/C
cloc
k, unknown mode, p1 = 1, p2 = 0)
pipe B dot 0 n 0 m1 0 m2 0 p1 1 p2 10
- FENCE START 0: 0x00c5b003

Comparing 3.11 with vga= with 3.13 in workig form is similar differences (DPLL
and fences) but also
- GEN6_PMIMR: 0x00000000
- GEN6_PMINTRMSK: 0x00000000
+ GEN6_PMIMR: 0xffffff8f
+ GEN6_PMINTRMSK: 0x0000000a
