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>
