* OMAP: DSS2: Create an enum for DSI pixel formatsArchit Taneja2011-09-301-2/+8
| | | | | | | | | | | | | | | | | | | Currently, DSI pixel info is only represented by the pixel size in bits using the pixel_size parameter in omap_dss_device struct's ctrl member. This is not sufficient information for DSI video mode usage, as two of the supported formats(RGB666 loosely packed, and RGB888) have the same pixel container size, but different data_type values for the video mode packet header. Create enum "omap_dss_dsi_pixel_format" which describes the pixel data format the panel is configured for. Create helper function dsi_get_pixel_size() which returns the pixel size of the given pixel format. Modify functions omapdss_default_get_recommended_bpp() and dss_use_replication() to use dsi_get_pixel_size().

* OMAP: DSS2: Fix FIFO threshold and burst size for OMAP4Tomi Valkeinen2011-07-011-7/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DMA FIFO threshold registers and burst size registers have changed for OMAP4. The current code only handles OMAP2/3 case, and so the values are a bit off for OMAP4. A summary of the differences between OMAP2/3 and OMAP4: Burst size: OMAP2/3: 4 x 32 bits / 8 x 32 bits / 16 x 32 bits OMAP4: 2 x 128 bits / 4 x 128 bits / 8 x 128 bits Threshold size: OMAP2/3: in bytes (8 bit units) OMAP4: in 128bit units This patch fixes the issue by creating two new helper functions in dss_features: dss_feat_get_buffer_size_unit() and dss_feat_get_burst_size_unit(). These return (in bytes) the unit size for threshold registers and unit size for burst size register, respectively, and are used to calculate correct values. For the threshold size the usage is straightforward. However, the burst size register has different multipliers for OMAP2/3 and OMAP4. This patch solves the problem by defining the multipliers for the burst size as 2x, 4x and 8x, which fit fine for the OMAP4 burst size definition (i.e. burst size unit for OMAP4 is 128bits), but requires a slight twist on OMAP2/3 by defining the burst size unit as 64bit. As the driver in practice always uses the maximum burst size, and no use case currently exists where we would want to use a smaller burst size, this patch changes the driver to hardcode the burst size when initializing DISPC. This makes the threshold configuration code somewhat simpler. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* OMAP: DSS2: remove update_mode from omapdssTomi Valkeinen2011-07-011-45/+0
| | | | | | | | Remove the whole update_mode stuff from omapdss driver. If automatic update for manual update displays is needed, it's better implemented in higher layers. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* OMAP: DSS2: Convert simple/strict_strto* to kstrto*Tomi Valkeinen2011-05-111-15/+29
| | | | | | | | | | | Convert simple/strict_strto* functions to kstrto* functions. Only simple cases are converted. simple_strto* uses are still left to places where it is used to parse numbers from a list of numbers. These need some other solution than kstrto*.

* OMAP: DSS2: remove sub-panel systemTomi Valkeinen2010-02-181-30/+2
| | | | | | | | | | | | The system to allow panel drivers to exists as attached to ctrl drivers did never work very well. It is not useed, and this patch removes it to make the driver cleaner. For now, controller drivers need to include also the panel driver code. In the future a proper mechanism for this should be developed, perhaps by creating busses for controllers.
