gpu: ipu-v3: do not divide by zero if the pixel clock is too large

2015-02-23T16:18:59Z

Even if an unsupported mode with a pixel clock larger than two times the 264 MHz IPU HSP clock is set, don't divide by zero. Signed-off-by: Philipp Zabel

gpu: ipu-v3: Fix IC control register offset

2015-01-27T15:28:01Z

The IC register offset is at +0x20000 relative to the control module registers on all IPUv3 versions. This patch fixes wrong values for i.MX51 and i.MX53. Signed-off-by: Philipp Zabel

gpu: ipu-v3: wait_for_completion_timeout does not return negative status

2015-01-27T14:55:49Z

This fixes up the return value handling and the return type. Signed-off-by: Nicholas Mc Guire Signed-off-by: Philipp Zabel

gpu: ipu-di: Switch to DIV_ROUND_CLOSEST for DI clock divider calc

2015-01-07T18:15:04Z

We can use the DIV_ROUND_CLOSEST() macro when calculating the DI clock divider, rounded to nearest int. Suggested-by: Philipp Zabel Signed-off-by: Steve Longerbeam Signed-off-by: Philipp Zabel

gpu: ipu-v3: Use videomode in struct ipu_di_signal_cfg

2015-01-07T18:15:03Z

This patch changes struct ipu_di_signal_cfg to use struct videomode to define video timings and flags. Signed-off-by: Steve Longerbeam Signed-off-by: Philipp Zabel

gpu: ipu-di: remove some non-functional code

2015-01-07T18:12:07Z

h_total and v_total were calculated in ipu_di_init_sync_panel() but never actually used. Remove. Signed-off-by: Steve Longerbeam Signed-off-by: Philipp Zabel

gpu: ipu-di: Add ipu_di_adjust_videomode()

2015-01-07T18:12:07Z

On some monitors, high resolution modes are not working, exhibiting pixel column truncation problems (for example, 1280x1024 displays as 1280x1022). The function ipu_di_adjust_videomode() aims to fix these issues by adjusting a passed videomode to IPU restrictions. The function can be called from the drm_crtc_helper_funcs->mode_fixup() methods.

gpu: ipu-v3: Implement use counter for ipu_dc_enable(), ipu_dc_disable()

2015-01-06T16:36:14Z

The functions ipu_dc_enable() and ipu_dc_disable() enable/disable the DC globally in the IPU_CONF register, but the DC is used by multiple clients on different DC channels. So make sure to only disable/enable the DC globally based on a use counter. Signed-off-by: Steve Longerbeam Signed-off-by: Philipp Zabel

[media] gpu: ipu-v3: Make use of media_bus_format enum

2014-11-14T19:55:27Z

In order to have subsytem agnostic media bus format definitions we've moved media bus definition to include/uapi/linux/media-bus-format.h and prefixed enum values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT. Reference new definitions in the ipu-v3 driver.
