2009-09-08drm/i915: fix mask bits settingZhenyu Wang
eDP is exclusive connector too, and add missing crtc_mask setting for TV.

2009-08-24drm/i915: Set crtc/clone mask in different output devicesMa Ling
Based on Bspec each encoder has different sharing pipe property, i.e. Integrated or SDVO TV both will occupy one pipe exclusively, and sdvo-non-tv and crt are allowed to share one. The patch moves sharing judgment into differnet output functions, and sets the right clone bit. This fixes both HDMI outputs choosing the same pipe. https://bugs.freedesktop.org/show_bug.cgi?id=22247 Signed-off-by: Ma Ling <ling.ma@intel.com> Reviewed-by : Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>
2009-07-29drm/i915: Add eDP support on IGDNG mobile chipZhenyu Wang
This adds embedded DisplayPort support on next mobile chip which aims to replace origin LVDS port. VBT's driver feature block has been used to determine the type of current internal panel for eDP or LVDS. Currently no panel fitting support for eDP and backlight control would be added in future.

2009-07-29drm/i915: Fix channel ending action for DP aux transactionZhenyu Wang
We should use current channel 'status' bits to clear DP aux channel's done and error bits, instead of using the channel setting bits, that will set send/busy bit again to initiate new transaction. This also includes also some minor cleanup. Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>
2009-07-01drm/i915: Make driver less chattyKeith Packard
Convert many printk calls to DRM_DEBUG calls to reduce kernel log noise for normal activities. Switch other printk calls to DRM_ERROR or DRM_INFO. Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Eric Anholt <eric@anholt.net>
2009-06-18drm/i915: Generate 2MHz clock for display port aux channel I/O. Retry I/O.Keith Packard
The display port aux channel clock is taken from the hrawclk value, which is provided to the chip as the FSB frequency (as far as I can determine). The strapping values for that are available in the CLKCFG register, now used to select an appropriate divider to generate a 2MHz clock. In addition, the DisplayPort spec requires that each aux channel I/O be retried 'at least 3 times' in case the sink is idle when the first request comes in.
