From 22e743898dcd693cf587593781699db2fa888e23 Mon Sep 17 00:00:00 2001 From: Daniel Scheller Date: Sat, 12 Aug 2017 07:55:52 -0400 Subject: [PATCH] media: ddbridge: bump ddbridge code to version 0.9.29 This huge patch bumps the ddbridge driver to version 0.9.29. Compared to the vendor driver package, DD OctoNET including GTL link support, and all DVB-C Modulator card support has been removed since this requires large changes to the underlying DVB core API, which should eventually be done separately, and, after that, the functionality/device support can be added back rather easy. While the diff is rather large, the bump is mostly a big refactor of all data structures. Yet, the MSI support (message signaled interrupts) is greatly improved, also all currently available CI single/duo bridge cards are fully supported. More changes compared to the upstream driver: - the DDB_USE_WORKER flag/define was removed, kernel worker functionality will be used. - coding style is properly fixed (zero complaints from checkpatch) - all (not much though) CamelCase has been fixed to kernel_case - (private) IOCTLs temporarily removed (which are mainly used to provide rarely-used FPGA update functionality) Great care has been taken to keep all previous changes and fixes (e.g. kernel logging via dev_*(), pointer annotations and such) intact. Permission to reuse and mainline the driver code was formally granted by Ralph Metzler .
