Subject: [PATCH] drm/radeon/aux: fix hpd assignment for aux bus
The hpd (hot plug detect) pin assignment got lost
in the conversion to to the common i2c over aux
code. Without this information, aux transactions
do not work properly. Fixes DP failures.

3.15.0-rc2 radeon HD 7480D [Aruba] blank display
I've just built 3.15.0-rc2 on this box, and discovered that I get a blank screen. The boot appears to complete (it sends me information from SMART which is from my last bootscript), and it responds to MagicSysRQ to reboot. I tried to login and run startx, but that didn't seem to make any difference - possibly something went wrong, it wasn't in my history when I booted a good kernel. This machine uses a regular old VGA cable to connect it, the following lines in dmesg make me think it has chosen the wrong connector: Apr 21 19:32:45 bluesbreaker kernel: [1.273246] [drm:radeon_dp_link_train_cr] *ERROR* displayport link status failed Apr 21 19:32:45 bluesbreaker kernel: [1.273247] [drm:radeon_dp_link_train_cr] *ERROR* clock recovery failed Apr 21 19:32:45 bluesbreaker kernel: [1.295116] Console: switching to colour frame buffer device 85x34 On a boot with 3.14.0 and earlier I get a different console size - Apr 21 20:42:44 bluesbreaker kernel: [1.445992] Console: switching to colour frame buffer device 133x54 My console font is 12x22, and my screen is 1600x1200 but it looks as if 3.15-rc2 has fallen back to trying to use 1024x768. I'm attaching what look like the relevant parts of the messages from the system logs for 3.15-rc2 and 3.14.0. Any ideas, please ?

3.15.0-rc2 radeon HD 7480D [Aruba] blank display
I've just built 3.15.0-rc2 on this box, and discovered that I get a blank screen. The boot appears to complete (it sends me information from SMART which is from my last bootscript), and it responds to MagicSysRQ to reboot. I tried to login and run startx, but that didn't seem to make any difference - possibly something went wrong, it wasn't in my history when I booted a good kernel.

Subject: [PATCH] drm/radeon/aux: fix hpd assignment for aux bus
The hpd (hot plug detect) pin assignment got lost
in the conversion to to the common i2c over aux
code. Without this information, aux transactions
do not work properly. Fixes DP failures.
