# \[GIT PULL\] OMAP DSS fixes for 3.3-rc - List: linux-fbdev - 7 messages, 3 authors - Page: https://ratatoskr.run/linux-fbdev/2012/01/13462549/t ## \[GIT PULL\] OMAP DSS fixes for 3.3-rc - From: Tomi Valkeinen \ - Date: 2012-01-26 12:07:31 - Message: https://ratatoskr.run/linux-fbdev/2012/01/13462549.md ```text Hi Florian, Here are two major fixes for OMAP DSS driver. The first (OMAPDSS: use sync versions...) fixes problem with system suspend, which causes omapdss power management to give WARNs and generally malfunction on system suspend/resume. The second (the rest of the patches) implements a workaround for HW bug, which causes physical damage to the board if the HDMI cable is disconnected at a "wrong" time. The actual fix is in the last patch, but the board files needed some cleanups and a new GPIO, which is what the smaller patches do. The branch is based on fbdev/fbdev-next. Is that ok?

Yes, that worked well, as I didn't start to collect 3.4 material there. Merged.

Managing the clocks for OMAP4 is not very simple, and this patch circumvents the problems we have in the clock framework. It's a clean but rather hacky fix, but it shouldn't cause any side-effects. The issue will hopefully be fixed properly with DT when we'll get proper parent-child hierarchy for DSS HW submodules. The second one is a simple fix for HDMI hotplug detection, which I missed when I wrote the HDMI PHY fix (c49d005b6cc8491fad5b24f82805be2d6bcbd3dd).
