In ancient times it was necessary to manually initialize the bus field of an
spi_driver to spi_bus_type. These days this is done in spi_driver_register(),
so we can drop the manual assignment.The patch was generated using the following coccinelle semantic patch:
//
@@
identifier _driver;
@@
struct spi_driver _driver = {
.driver = {
- .bus = &spi_bus_type,
},
};

While the OLPC display appears to be able to handle either positive
or negative sync, the Display Controller only recognises positive sync.This brings viafb (for XO-1.5) in line with lxfb (for XO-1) and
fixes a recent regression where the XO-1.5 DCON could no longer be
frozen. Thanks to Florian Tobias Schandinat for helping identify
the fix.Test case: from a vt,
echo 1 > /sys/devices/platform/dcon/freeze
should cause the current screen contents to freeze, rather than garbage being
displayed.Signed-off-by: Daniel Drake

VMLEN1/VMLEN2 needs blanking length which is calculated from
video image size.The calculation methods are explained on
[SH MIPI] - [Video Mode] - [Blanking Packet setting]
But HFPLEN (= VMLEN2) is un-understandable.For example, if SH-MIPI input was RGB888 (3byte),
output was RGB888 (3byte)
and 3lane connection, the date goes straight.But if SH-MIPI input was RGB888 (3byte),
output was RGB565 (2byte)
and 4lane connection, it needs delay in HFPLEN.
Then (input cycle - output cycle) * lane is necessary the delaySigned-off-by: Kuninori Morimoto

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 HzA 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.Signed-off-by: Tomi Valkeinen

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,
