From: Jesse Barnes Date: Wed, 1 Jul 2009 17:04:40 +0000 (-0700) Subject: drm: clarify scaling property names X-Git-Tag: Ubuntu-5.13.0-19.19~34197^2~111 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=53bd83899f5ba6b0da8f5ef976129273854a72d4;p=mirror_ubuntu-jammy-kernel.git drm: clarify scaling property names Now that we're using the scaling property in the Intel driver I noticed that the names were a bit confusing. I've corrected them according to our discussion on IRC and the mailing list, though I've left out potential new additions for a new scaling property with an integer (or two) for the scaling factor. None of the drivers implement that today, but if someone wants to do it, I think it could be done with the addition of a single new type and a new property to describe the scaling factor in the X and Y directions.
