Nikolaus Schaller" Subject: [PATCH v3 0/8] ARM/MIPS: DTS: add child nodes describing the PVRSGX GPU present in some OMAP SoC and JZ4780 (and many more) Date: Sun, 24 Nov 2019 12:40:20 +0100 Message-Id: X-Mailer: git-send-email 2.23.0 MIME-Version: 1.0 Sender: linux-omap-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-omap@vger.kernel.org * reworked YAML format with help by Rob Herring * removed .txt binding document * change compatible "ti,am335x-sgx" to "ti,am3352-sgx" - suggested by Tony Lindgren PATCH V2 2019-11-07 12:06:17: * tried to convert bindings to YAML format - suggested by Rob Herring * added JZ4780 DTS node (proven to load the driver) * removed timer and img,cores properties until we know we really need them - suggested by Rob Herring PATCH V1 2019-10-18 20:46:35: This patch series defines child nodes for the SGX5xx interface inside different SoC so that a driver can be found and probed by the compatible strings and can retrieve information about the SGX revision that is included in a specific SoC. It also defines the interrupt number to be used by the SGX driver. There is currently no mainline driver for these GPUs, but a project [1] is ongoing with the goal to get the open-source part as provided by TI/IMG and others into drivers/gpu/drm/pvrsgx. The kernel modules built from this project have successfully demonstrated to work with the DTS definitions from this patch set on AM335x BeagleBone Black, DM3730 and OMAP5 Pyra and Droid 4. They partially work on OMAP3530 and PandaBoard ES but that is likely a problem in the kernel driver or the (non-free) user-space libraries and binaries. Wotk for JZ4780 (CI20 board) is in progress and there is potential to extend this work to e.g. BananaPi-M3 (A83) and some Intel Poulsbo and CedarView devices.
