* OMAPDSS: DSI: implement generic DSI pin configTomi Valkeinen2012-05-092-65/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for device tree, this patch changes how the DSI pins are configured. The current configuration method is only doable with board files and the configuration data is OMAP specific. This patch moves the configuration data to the panel's platform data, and the data can easily be given via DT in the future. The configuration data format is also changed to a generic one which should be suitable for all platforms. The new format is an array of pin numbers, where the array items start from clock + and -, then data1 + and -, and so on. For example: { 0, // pin num for clock lane + 1, // pin num for clock lane - 2, // pin num for data1 lane + 3, // pin num for data1 lane - ... } The pin numbers are translated by the DSI driver and used to configure the hardware appropriately.

* OMAPDSS: panel-dvi: add PD gpio handlingTomi Valkeinen2012-05-091-0/+31
| | | | | | | | | | The driver for the TFP410 chip should handle the power-down signal of the chip, instead of the current way of handling it in the board files. This patch adds power_down_gpio into the device's platform data, and adds the necessary code in the driver to request and handle the GPIO. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

There doesn't seem to be any reason for that, and additionally the soon-to-be-merged patch "ARM: OMAP: omap_device: remove omap_device_parent" will break omapdss initialization with the current registration model. This patch changes the registration for all drivers to happen at the same place, in the init of the module.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the shadow-dirty flags for manual update displays is cleared in the apply_irq_handler when an update has finished.

The call to extra_info_update_ongoing() should really be inside spinlock, but that's a bit heavy just for verification. Rather than that, check the return value of the wait_for_completion_timeout() and print an error if it has timeouted or returned an error. Even better would be to return the error value and act on it in the callers of wait_pending_extra_info_updates. However, it's not clear what the callers should do in case of an error, as the error should only happen if there's a bug in the driver or the HW. So we'll just print the warning for now.

| * | | | OMAPDSS: cleanup probe functionsTomi Valkeinen2012-02-215-71/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that dss is using devm_ functions for allocation in probe functions, small reordering of the allocations allows us to clean up the probe functions more. This patch moves "unmanaged" allocations after the managed ones, and uses plain returns instead of gotos where possible. This lets us remove a bunch of goto labels, simplifying the probe's error handling. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

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.

These are similar to the other info/dirty flags in ovl_priv_data and ovl_mgr_data, but fifo merge is a common attribute to all managers and thus outside the ovl_mgr_data. The fifo-merge field is used in the dss_write_regs_common, which handles writing the register. dss_apply_fifo_merge() can be used to set/unset the fifo merge field in the dss_data.
