| | | * | | OMAPFB: Move old omapfb private structs to a private include fileTomi Valkeinen2012-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | include/linux/omapfb.h contains structs that are used only by the omapfb driver. Move the structs into drivers/video/omap/omapfb.h. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

| | | * | | OMAPFB: remove mem info from platform_dataTomi Valkeinen2012-02-23

This patch removes omapfb's (both old and new omapfb) use of the memory data in platform_data, because: - No board uses them currently - It's not board file's job to define things like amount of default framebuffer memory. These should come from the bootloader via command line parameters. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| | | * | | OMAPFB: remove early mem alloc from old omapfbTomi Valkeinen2012-02-23

This code isn't currently used by any board, and is anyway something that the newer vram.c could handle. So remove the alloc code and in later patches make old omapfb driver use vram.c.

| | | * | | OMAP: N770: remove HWA742 platform dataTomi Valkeinen2012-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In an effort to clean up the old omapfb driver, this patch removes HWA742 (the display chip used in N770) platform data. This can be done as N770 is the only user of HWA742, and the platform data contains only one field, te_connected, which we can just presume to be true in the HWA742 driver. This allows us to remove omapfb_set_ctrl_platform_data(), and the mechanism to pass the platform data, in a later patch.

Also, devices that do not support the MCLK, use the TMDS clock directly by leaving ACR_CTRL[2] set to 0. The MLCK clock divisor, mclk_mode, is configured only if MLCK is used. Such configuration is no longer related to the CTS mode as in some silicon revisions CTS SW-mode is used along with the MCLK.

This should greatly increase the time between pixel data fetches from SDRAM, as the usable fifo size is much larger. However, it probably won't help for fifo underflows, as the low threshols is kept the same. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

This is done mainly in four functions: mgr_enable/disable and ovl_enable/disable. These are the functions where overlays are taken into and out of active use. The process to enable and disable fifo-merge is not simple. We need to do it in steps, waiting in between for certain settings to be taken into use, and continuing after that. The reason for this is that fifo-merge is a common thing for all managers/overlays, and its use must be synchronized. As an example, when we disable an overlay, we first set the overlay as disabled, then wait until the overlay is actually disabled in the HW, and only after that we may re-configure the fifos, possibly taking fifo-merge into use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As check_var already ensures that the mode is valid there is no need to do those expensive lookups here again. The only thing that might change is that the deprecated interface could report slightly different refresh rates due to rounding errors.

| | * | | | | viafb: modetable conversionFlorian Tobias Schandinat2012-03-08

Otherwise the behaviour should be the same as before. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes redundant bits per pixel information by using the one storged in var directly. Simplifies code without any functional changes. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

The infrastructure will be used to replace and extend the support that is scattered throughout viafb. The stub drivers are not very useful yet but they show how the infrastructure works, provide information about the chips integrated into a system and maybe gather some testers as it would be very difficult for a single person to get a sane test environment. The only thing this actually does is probing the I2C busses which will hopefully not cause any regressions. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
