2017-08-16drm/omap: add OMAP5 DSIPHY lane-enable supportTomi Valkeinen1-8/+39
We are missing OMAP5 DSIPHY lane-enable support, which has prevented OMAP5 DSI working in mainline. This patch adds the lane-enable similarly to the recently added OMAP4 version. Signed-off-by: Tomi Valkeinen <[email protected]> Reviewed-by: Laurent Pinchart <[email protected]>
2017-08-16drm/omap: use regmap_update_bit() when muxing DSI padsTomi Valkeinen1-12/+3
Use regmap_update_bits instead of regmap_read/write, which simplifies the code. Signed-off-by: Tomi Valkeinen <[email protected]> Reviewed-by: Laurent Pinchart <[email protected]>
2017-08-15drm: omapdrm: Remove dss_features.hLaurent Pinchart1-1/+0
The header file only contains four macros, two of which are never used. Move the other two to dss.h and remove dss_features.h. Signed-off-by: Laurent Pinchart <[email protected]> Signed-off-by: Tomi Valkeinen <[email protected]>
2017-08-15drm: omapdrm: Move FEAT_PARAM_DSI* features to dsi driverLaurent Pinchart1-6/+19

2017-08-15drm: omapdrm: dsi: Store DSI model and PLL hardware data in OF dataLaurent Pinchart1-61/+55
The DSI PLL hardware data and DSS channels are selected based on the OMAP SoC model. There's no need for fine-grained model information, as the driver only needs to differentiate between OMAP3, OMAP4 and OMAP5. As this can be done through the DSI compatible string, store the corresponding information in OF match data instead to avoid accessing the OMAP SoC model.

2017-06-02drm: omapdrm: Remove duplicate error messages when mapping memoryLaurent Pinchart1-18/+9
The devm_ioremap_resource() call can handle being given a NULL resource, and prints an error message when mapping fails. Switch the remaining devm_ioremap() calls to devm_ioremap_resource() and remove all extraneous resource NULL checks and error messages printed manually by the driver.

2017-04-06drm: omap: use common OF graph helpersRob Herring1-1/+2
The OMAP driver has its own OF graph helpers that are similar to the common helpers. This commit replaces most of the calls with the common helpers. There's still a couple of custom helpers left, but the driver needs more extensive changes to get rid of them. In dss_init_ports, we invert the loop, looping through the known ports and matching them to DT nodes rather than looping thru DT nodes and matching them to the ports.

2017-04-03drm/omap: display: don't use dsi_get_pixel_size()Tomi Valkeinen1-1/+1
display.c uses dsi_get_pixel_size() which is implemented in the DSI driver, and we won't have that in the omapdss-base module, to which we want to move display.c This patch changes display.c not to use dsi_get_pixel_size(). The call can be replaced with a simple check for OMAP_DSS_DSI_FMT_RGB565. We can also make dsi_get_pixel_size() static as it's no longer used outside dsi.c.

2016-05-31drm/omap: Remove regulator API abusePeter Ujfalusi1-9/+0
regulator_can_change_voltage() is deprecated and it's use is not necessary as commit: 6a0028b3dd67b regulator: Deprecate regulator_can_change_voltage() describers it clearly. Also, regulator_set_voltage() is misused in the driver, as it is supposed to be used only in cases where the regulator voltage needs to be changed dynamically at runtime. In DSS's case, we always want a fixed voltage, set in the .dts files. Signed-off-by: Peter Ujfalusi <[email protected]> Signed-off-by: Tomi Valkeinen <[email protected]>

2016-05-19drm/omap: add field for PLL typeTomi Valkeinen1-0/+6
DSS uses two types of PLLs, type A (DSI & Video) and type B (HDMI). The two types behave slightly differently, but we don't have the type of the PLL available anywhere for the driver.
