From a49d25364dfb9f8a64037488a39ab1f56c5fa419 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Fri, 17 Feb 2017 16:55:17 +0000 Subject: staging/atomisp: Add support for the Intel IPU v2 This patch adds support for the Intel IPU v2 as found on Android and IoT Baytrail-T and Baytrail-CR platforms (those with the IPU PCI mapped). You will also need the firmware files from your device (Android usually puts them into /etc) - or you can find them in the downloadable restore/upgrade kits if you blew them away for some reason. It may be possible to extend the driver to handle the BYT/T windows platforms such as the ASUS T100TA. These platforms don't expose the IPU via the PCI interface but via ACPI buried in the GPU description and with the camera information somewhere unknown so would need a platform driver interface adding to the codebase *IFF* the firmware works on such devices. To get good results you also need a suitable support library such as libxcam. The camera is intended to be driven from Android so it has a lot of features that many desktop apps don't fully spport. In theory all the pieces are there to build it with -DISP2401 and some differing files to get CherryTrail/T support, but unifying the drivers properlly is a work in progress. The IPU driver represents the work of a lot of people within Intel over many years. It's historical goal was portability rather than Linux upstream. Any queries about the upstream aimed driver should be sent to me not to the original authors.
