drm/panel: Changes for v4.1-rc1
This set of changes adds support for a whole bunch of new panels, mostly simple ones. There's now also support for panels to provide display timings rather than fixed modes, which should allow panels to work with a larger number of display drivers. Eventually drivers should migrate to this new interface and the fixed modes removed from panels. There are also a couple of sparse fixes for the PS8622 and PS8625 bridge drivers. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJVHXdzAAoJEN0jrNd/PrOhWKgQAJGdicIa3B8CLohgAfyMI+in 1PxO2vBGgz7T02iFTOzwh5cvh8E7mog9/R5jVCyan22BHdws75FgL6RVMcqbllds c2ejPHhHlBEzOBtbZeEmvg1twmqKY5ejk1X7rtVHNCNaXVzSlpxYJF2jfK8DmhRF l7UmjKIpyeDSL+33t+Q0jZynU2mwLfstr/4lwMPPKU6kzz15lIo0gPAnOlagbGD3 L5GOm1+LaDXpxojDtIElzzhzDf1DhmD4nIA3KRGAmKHRxA1u/vZUsW5UNaCvJB0v eMVFdIk/aFfw4jizlAEute4sMKcXWNBMHmEr7e8Bakr+clie7BcXN9zeZ+B99t7A +pkRbWNN8Isr4FpGNVz0XdU2BzmJAaQ59ghmZ5ZJtOmZwMWJbJsG7vMw0p2+68w6 bxhrEoT7hQDUicoKhcM6/8jDCqLZdqN0co16NHIL+0/BiUuS9Q1qr3Y7dBFbiU6D iNKKeniODw8lA+Jv7wxVGbS2f5RvFeLvhgi4MgF78bEj8Mxf2EpB+mJT6WtEcX37 OMcg7xN7C6q2cu4Cpj7txF3gnKwB56lkJsX7xnyajtdHLDcw8Vx4CZprZCyA5gWP FWpDLkT7l3Fi3jRDoVBw3WRa+rIfSFvLuVf3iLyVuFE5vR0tqJKutYDeaez0cMQM nQqS1f2MYsKmNJf2DFhx =0aBn -----END PGP SIGNATURE----- Merge tag 'drm/panel/for-4.1-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next drm/panel: Changes for v4.1-rc1 This set of changes adds support for a whole bunch of new panels, mostly simple ones.
