From: Maoguang Meng <maoguang.m...@mediatek.com> MTK H264 Encoder(VENC_SYS) and VP8 Encoder(VENC_LT_SYS) are two independent hardware instance. They have their owner interrupt, register mapping, and special clocks.
This patch seperates the two instance. This is a preparing patch for adding device_link between the larbs and venc-device. It's mainly for fixing the problem: https://lkml.org/lkml/2019/9/3/316 User Call "VIDIOC_QUERYCAP": H264 Encoder return driver name "mtk-vcodec-enc"; VP8 Encoder return driver name "mtk-venc-vp8.
