      ARM: OMAP2/3: PRM: fix bogus OMAP2xxx powerstate return values · 7e7fff82
      Paul Walmsley authored
      On OMAP2xxx chips, the register bitfields for the
      PM_PWSTCTRL_*.POWERSTATE and PM_PWSTST_*.LASTSTATEENTERED are
      different than those used on OMAP3/4.  The order is reversed.  So, for
      example, on OMAP2xxx, 0x0 indicates 'ON'; but on OMAP3/4, 0x0
      indicates 'OFF'.  Similarly, on OMAP2xxx, 0x3 indicates 'OFF', but on
      OMAP3/4, 0x3 indicates 'ON'.
      
      To fix this, we treat the OMAP3/4 values as the powerdomain API
      values, and create new low-level powerdomain functions for the
      OMAP2xxx chips which translate between the OMAP2xxx values and the
      OMAP3/4 values.
      
      Without this patch, the conversion of the OMAP2xxx PM code to the
      functional powerstate code results in a non-booting kernel.
