dmaengine/dma_slave: introduce inline wrappers

2012-03-21T13:50:22Z

Add inline wrappers for device_prep_slave_sg() and device_prep_dma_cyclic() interfaces to hide new parameter from current users of affected interfaces. Convert current users to use new wrappers instead of direct calls. Suggested by Russell King [https://lkml.org/lkml/2012/2/3/269]. Signed-off-by: Alexandre Bounine Signed-off-by: Vinod Koul

video i.MX IPU: Fix display connections

2011-12-08T07:29:03Z

The IPU internally works on 32bit colors. It can arbitrarily map between pixel formats and internal representation and also between internal representation and the physical connection to the display. The driver used to change the mapping between internal representation and display connection depending on the user selected bpp which is wrong. Instead, the mapping is specified by the hardware, so an additional field in platform data is added to describe the connection between i.MX and the display. The default for this field is RGB666 which seems to be the only configuration which works without this patch, so I assumed that all in Kernel boards are connected this way. This patch has been tested on a RGB666 connected display and a RGB888 connected display in both 16bpp and 32bpp modes. Signed-off-by: Sascha Hauer Signed-off-by: Vinod Koul

mx3fb: fix NULL pointer dereference in screen blanking.

2011-10-03T15:52:32Z

When blanking an already blanked framebuffer, a kernel NULL pointer dereference occurred, because mx3fb driver handles all kinds of screen blanking (normal, vsync suspend, powerdown) in the same way. Certain programs (Xorg X11 server) first do a normal blank, followed by a powerdown blank, which triggered the bug. Add an additional safeguard and make sdc_disable_channel() safe against multiple calls independent of other logic. Signed-off-by: Michael Thalmeier Signed-off-by: Florian Tobias Schandinat

mx3fb: use display information in info not in var for panning

2011-08-19T08:32:52Z

We must not use any information in the passed var besides xoffset, yoffset and vmode as otherwise applications might abuse it. Also use the aligned fix.line_length and not the (possible) unaligned xres_virtual. Signed-off-by: Laurent Pinchart Tested-by: Guennadi Liakhovetski

console: rename acquire/release_console_sem() to console_lock/unlock()

2011-01-26T00:50:06Z

The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock. The only real change is the return value of console_trylock which is inverted from try_acquire_console_sem() This patch also paves the way to switching console_sem from a semaphore to a mutex.

ARM mx3fb: check for DMA engine type

2010-11-15T08:25:01Z

We have two dma engines in MX3 systems: The IPU and the SDMA engine. We have to check if we got a channel from the correct engine before proceeding with a channel. Signed-off-by: Sascha Hauer Cc: Guennadi Liakhovetski Reviewed-by: Guennadi Liakhovetski
