gpu: ipu-v3: Move i.MX IPUv3 core driver out of staging The i.MX Image Processing Unit (IPU) contains a number of image processing blocks that sit right in the middle between DRM and V4L2. Some of the modules, such as Display Controller, Processor, and Interface (DC, DP, DI) or CMOS Sensor Interface (CSI) and their FIFOs could be assigned to either framework, but others, such as the dma controller (IDMAC) and image converter (IC) can be used by both. The IPUv3 core driver provides an internal API to access the modules, to be used by both DRM and V4L2 IPUv3 drivers.

drm: Drop ARCH_MULTIPLATFORM from dependencies Some of these dependencies used to be sensible when only a small part of the platforms supported by ARCH=arm could be compiled together in a single kernel image. Nowadays ARCH_MULTIPLATFORM is only used as a guard for kernel options incompatible with a multiplatform image. See commit 84fc86360623 ("ARM: make ARCH_MULTIPLATFORM user-visible") for some more details.

gpu: ipu-v3: add DRM dependency The new PRE/PRG driver code causes a link failure when IPUv3 is built-in, but DRM is built as a module: drivers/gpu/ipu-v3/ipu-pre.o: In function `ipu_pre_configure': ipu-pre.c:(.text.ipu_pre_configure+0x18): undefined reference to `drm_format_info' drivers/gpu/ipu-v3/ipu-prg.o: In function `ipu_prg_format_supported': ipu-prg.c:(.text.ipu_prg_format_supported+0x8): undefined reference to `drm_format_info' Adding a Kconfig dependency on DRM means we don't run into this problem any more. If DRM is disabled altogether, the IPUv3 driver is built without PRE/PRG support. Fixes: ea9c260514c1 ("gpu: ipu-v3: add driver for Prefetch Resolve Gasket") Link: https://patchwork.kernel.org/patch/9636665/ Signed-off-by: Arnd Bergmann <arnd@arndb.de> [p.zabel@pengutronix.de: changed the dependency from DRM to DRM || !DRM, since the link failure only happens when DRM=m and IPUV3_CORE=y. Modified the commit message to reflect this.] Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

Choose this if you have a i.MX5/6 system and want to use the Image
Processing Unit. This option only enables IPU base support.
