2017-08-23drm/omap: fix i886 work-aroundTomi Valkeinen1-0/+2
7d267f068a8b4944d52e8b0ae4c8fcc1c1c5c5ba ("drm/omap: work-around for errata i886") changed how the PLL dividers and multipliers are calculated. While the new way should work fine for all the PLLs, it breaks omap5 PLLs. The issues seen are rather odd: seemed that the output clock rate is half of what we asked. It is unclear what's causing there issues. As a work-around this patch adds a "errata_i886" flag, which is set only for DRA7's PLLs, and the PLL setup is done according to that flag.

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 <laurent.pinchart@ideasonboard.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2017-06-02drm: omapdrm: Remove duplicate error messages when mapping memoryLaurent Pinchart1-18/+2
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.

2016-06-07Merge omapdss header refactoringTomi Valkeinen1-2/+1
Merge omapdss public header refactoring, which separates the public header into omapdrm and omapfb parts.

2016-05-19drm/omap: add field for PLL typeTomi Valkeinen1-0/+2
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. This patch adds an enum for the PLL type and a field in the PLL's HW data to store it. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2016-05-19drm/omap: video-pll: add missing data for clkout2 & 3Tomi Valkeinen1-0/+4
Video pll hw data is missing bitfield definitions for clkout2 and clkout3. We don't use those clkouts at the moment, so this has not caused any issues. Add the bitfields. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2015-12-29drm/omap: move omapdss & displays under omapdrmTomi Valkeinen1-0/+211
Now that omapfb has its own copy of omapdss and display drivers, we can move omapdss and display drivers which omapdrm uses to omapdrm's directory. We also need to change the main drm Makefile so that omapdrm directory is always entered, because omapdss has a file that can't be built as a module.
