drm/i915/bxt: eDP Panel Power sequencing
Changes for BXT - added a IS_BROXTON check to use the macro related to PPS
registers for BXT.
BXT does not have PP_DIV register. Making changes to handle this.
Second set of PPS registers have been defined but will be used when VBT
provides a selection between the 2 sets of registers.
v2:
[Jani] Added 2nd set of PPS registers and the macro
Jani's review comments
- remove reference in i915_suspend.c
- Use BXT PP macro
Squashing all PPS related patches into one.
v3: Jani's review comments addressed
- Use pp_ctl instead of pp
- ironlake_get_pp_control() is not required for BXT
- correct the use of && in the print statement
- drop the shift in the print statement
v4: Jani's comments
- modify ironlake_get_pp_control() - dont set unlock key for bxt
v5: Sonika's comments addressed
- check alignment
- move pp_ctrl_reg write (after ironlake_get_pp_control())
to !IS_BROXTON case.
- check before subtracting 1 for t11_t12
