* drm: omapdrm: dsi: Store DSI model and PLL hardware data in OF dataLaurent Pinchart2017-08-151-61/+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.

* drm: omapdrm: Remove duplicate error messages when mapping memoryLaurent Pinchart2017-06-021-18/+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.

* drm: omap: use common OF graph helpersRob Herring2017-04-061-1/+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.

* drm/omap: display: don't use dsi_get_pixel_size()Tomi Valkeinen2017-04-031-1/+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.
