[PATCH v2 1/2] gpu: ipu-v3: vdic: Simplify ipu_vdi_setup()
From: Marek Vasut <marex@denx.de>
Date: 2024-07-24 00:22:01
Also in:
dri-devel, imx, linux-arm-kernel, linux-media, linux-staging
Subsystem:
drm drivers, drm drivers for freescale imx 5/6, framebuffer layer, media drivers for freescale imx, media input infrastructure (v4l/dvb), staging subsystem, the rest · Maintainers:
David Airlie, Simona Vetter, Philipp Zabel, Helge Deller, Steve Longerbeam, Mauro Carvalho Chehab, Greg Kroah-Hartman, Linus Torvalds
The 'code' parameter only ever selects between YUV 4:2:0 and 4:2:2 subsampling, turn it into boolean to select exactly that and update related code accordingly.
