      OMAPDSS: DISPC: skip scaling calculations when not scaling · f95cb5eb
      由 Tomi Valkeinen 提交于 
      Current code calculates scaling factors for video overlays even when the
overlays are not scaled. Change the code to skip calculations when not
scaling.

This optimizes the code a bit, but also fixes a problem when configuring
an overlay for a disabled display: if the display is disabled we don't
necessarily know the pixel clock used when the display is enabled, and
in some cases (like HDMI) the pixel clock is set to zero until a proper
video mode is set later. A wrong pixel clock will mess up the
scaling calculations, causing an error like:

omapdss DISPC error: failed to set up scaling, required fclk rate = 0
Hz, current fclk rate = 170666666 Hz

A proper fix would be to check later whether the clocks are enough for the
scaling, at the point when the overlay or display is actually enabled,
but this patch removes the problem for now.

      OMAPDSS: HDMI: fix returned HDMI pixel clock · ef319c6e
      由 Tomi Valkeinen 提交于 
      hdmi_get_pixel_clock() returns the pixel clock in Hz, but the pck is
stored as kHz. This means the return value has to be multiplied by 1000,
not by 10000 as the code did.

      fsl-rio: fix compile error · e0ce42e1
      由 Liu Gang 提交于 
      The "#include <linux/module.h>" was replaced by "#include <linux/export.h>"
in the patch "powerpc: various straight conversions from module.h --> export.h".
This will cause the following compile problem:
arch/powerpc/sysdev/fsl_rio.c: In function 'fsl_rio_mcheck_exception':
arch/powerpc/sysdev/fsl_rio.c:296: error: implicit declaration of function 'search_exception_tables'.

The file fsl_rio.c needs the declaration of function "search_exception_tables"
in the header file "linux/module.h".

      The following error is seen in some case when mounting rootfs from
SD/MMC cards.

  Waiting for root device /dev/mmcblk0p1...
  mmc1: host does not support reading read-only switch. assuming write-enable.

      由 Shawn Guo 提交于 
      The AUTO_ZRELADDR selection for ARCH_IMX_V4_V5 and ARCH_MX5 should
really be mutually exclusive to ZBOOT_ROM just like what ARCH_IMX_V6_V7
does.

      arm/imx: fix the references to ARCH_MX3 · 59198b6c
      由 Shawn Guo 提交于 
      The config symbol ARCH_MX3 has been removed by commit 'a89cf59b
arm/imx: merge i.MX3 and i.MX6', and it should not be referenced
any more.

The patch also change ARCH_MX* to SOC_IMX* for other platforms.
