Subject: sun6i: Sync PLL1 multipliers/dividers with Boot1
|
|
|
|
This change syncs up the multipliers and dividers used to initialize
|
|
PLL1 (i.e. the fast clock driving the ARM cores) with the values used
|
|
in Allwinner's Boot1 on sun6i.
|
|
|
|
More specifically, the following settings are now used:
|
|
* up to 768MHz: mul=2, div=2 (was: mul=1, div=1)
|
|
* up to 1152MHz: mul=3, div=2 (unchanged)
|
|
* above 1152MHz: mul=4, div=2 (was: mul=2, div=1)
