From: Boris Brezillon Date: Tue, 28 May 2019 17:02:24 +0000 (-0400) Subject: media: rockchip/vpu: Move encoder logic to a common place X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c65227fd2aac55f40f3b400e4a225e5846e3b47a;p=openwrt%2Fstaging%2Fblogic.git media: rockchip/vpu: Move encoder logic to a common place The V4L2/VB2 implementation for the encoder and decoder logic are very similar, so let's rename rockchip_vpu_enc.c file into rockchip_vpu_v4l2.c and remove the _enc_ part in objects/functions exposed in rockchip_vpu_v4l2.h. We also rename the enc_queue_init() function (in rockchip_vpu_drv.c) queue_init() since it will be used to initialize both type of queues. The implementation itself will be patched to support the decoding case when decoder support is added.
