      [ARM] pxamci: call mmc_remove_host() before freeing resources · 5d6b1edf
      Daniel Mack 提交于
      mmc_remove_host() will cause the mmc core to switch off the bus power by
      eventually calling pxamci_set_ios(). This function uses the regulator or
      the GPIO which have been freed already.
      
      This causes the following Oops on module unload.

      rtc-x1205: reset clock to sane state after power failure · cb8799ee
      Johannes Weiner 提交于
      When detecting power failure, the probe function would reset the clock
      time to defined state.
      
      However, the clock's _date_ might still be bogus and a subsequent probe
      fails when sanity-checking these values.
      
      Change the power-failure fixup code to do a full setting of rtc_time,
      including a valid date.

      rtc-x1205: fix rtc_time to y2k register value conversion · 48a7f774
      Johannes Weiner 提交于
      The possible CCR_Y2K register values are 19 or 20 and struct rtc_time's
      tm_year is in years since 1900.
      
      The function translating rtc_time to register values assumes tm_year to be
      years since first christmas, though, and we end up storing 0 or 1 in the
      CCR_Y2K register, which the hardware does not refuse to do.
      
      A subsequent probing of the clock fails due to the invalid value range in
      the register, though.
      
      [ And if it didn't, reading the clock would yield a bogus year because
        the function translating registers to tm_year is assuming a register
        value of 19 or 20. ]
      
      This fixes the conversion from years since 1900 in tm_year to the
      corresponding CCR_Y2K value of 19 or 20.

      a. Screen misalignment during booting when frame buffer console is
         enabled.
      
      b. Driver was configured always in PSEUDOCOLOR mode.  This patch
         dynamically configures the driver either in PSEUDOCOLOUR or TRUECOLOR
         mode depending on bpp.
      
      c. The RED and BLUE offsets were interchanged resulting in wrong
         bootup logo colour.
      
      This patch has been tested on DA830/OMAP-L137 and DA850/OMAP-L138 EVMs.
