When IOMMU_IOVA is not built-in but host1x is, we get a link error:
drivers/gpu/host1x/dev.o: In function `host1x_remove':
dev.c:(.text.host1x_remove+0x50): undefined reference to `put_iova_domain'
drivers/gpu/host1x/dev.o: In function `host1x_probe':

drivers/gpu/host1x/cdma.o: In function `host1x_cdma_deinit':
cdma.c:(.text.host1x_cdma_deinit+0xb0): undefined reference to `free_iova'
This adds the same select statement that we have for drm_tegra.

The Tegra host1x module is the DMA engine for register access to
|
|
Tegra's graphics- and multimedia-related modules. The modules served
|
|
by host1x are referred to as clients. host1x includes some other

functionality, such as synchronization.
