2021-02-18video: omapfb: Remove WARN_ON(in_interrupt()).Ahmed S. Darwish1-2/+0
dsi_sync_vc() uses in_interrupt() to create a warning if the function is used in non-preemptible context. The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. The wait_for_completion() function (used in dsi_sync_vc_vp() and dsi_sync_vc_l4() has already a check if it is invoked from proper context. Remove WARN_ON(in_interrupt()) from the driver.

2021-01-13video: omapfb2: Make standard and custom DSI command mode panel driver ↵Sebastian Reichel1-0/+1
mutually exclusive Standard DRM panel driver for DSI command mode panel used by omapfb2 is also available now. Just like the other panels its module name clashes with the module from drivers/video/fbdev/omap2/omapfb/displays, part of the deprecated omapfb2 fbdev driver. As omapfb2 can only be compiled when the omapdrm driver is disabled, and the DRM panel drivers are useless in that case, make the omapfb2 panel depend on the standard DRM panels being disabled to fix the name clash.

The drm/omap driver was fixed to correct an issue where using a divider of 32 breaks the DSS despite the TRM stating 32 is a valid number. Through experimentation, it appears that 31 works, and it is consistent with the value used by the drm/omap driver. This patch fixes the divider for fbdev driver instead of the drm.

2020-01-15OMAP: DSS2: remove non-zero check on variable rColin Ian King1-4/+0
Variable r is being initialized to zero, so the check of a non-zero rv is redundant and can be removed. It appears that the previous case statements set r to be -EINVAL and the "Fallthrough" comment afterwards suggested it was going to fall through to this non-zero check but won't because of the break statement. Remove the confusion by removing the Fallthrough comment too.

2019-12-05video: constify fb ops across all driversJani Nikula1-1/+1
Now that the fbops member of struct fb_info is const, we can start making the ops const as well. This does not cover all drivers; some actually modify the fbops struct, for example to adjust for different configurations, and others do more involved things that I'd rather not touch in practically obsolete drivers. Mostly this is the low hanging fruit where we can add "const" and be done with it. v3: - un-constify atyfb, mb862xx, nvidia and uvesabf (0day) v2: - fix typo (Christophe de Dinechin) - use "static const" instead of "const static" in mx3fb.c - also constify smscufx.c Cc: linux-fbdev@vger.kernel.org Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/ce67f14435f3af498f2e8bf35ce4be11f7504132.1575390740.git.jani.nikula@intel.com
2019-08-16video: omapfb2: Make standard and custom panel drivers mutually exclusiveLaurent Pinchart1-0/+5
Standard DRM panel drivers for several panels used by omapfb2 are now available. Their module name clashes with the modules from drivers/video/fbdev/omap2/omapfb/displays, part of the deprecated omapfb2 fbdev driver. As omapfb2 can only be compiled when the omapdrm driver is disabled, and the DRM panel drivers are useless in that case, make the omapfb2 panels depend on the standard DRM panels being disabled to fix the name clash.
