[ Upstream commit 2254182807fc09ba9dec9a42ef239e373796f1b2 ]
The DMA subsystem could be entirely disabled in Kconfig and then the
TEGRA20_APB_DMA option isn't available too. Hence kernel configuration
fails if DMADEVICES Kconfig option is disabled due to the unsatisfiable
dependency.
The FUSE driver isn't a critical driver and currently it only provides
NVMEM interface to userspace which isn't known to be widely used, and
thus, it's fine if FUSE driver fails to load.
Let's remove the erroneous Kconfig dependency and let the FUSE driver to
fail the probing if DMA is unavailable.
Fixes: 19d41e5e9c ("soc/tegra: fuse: Add APB DMA dependency for Tegra20")

the Tegra210 has four Cortex-A57 cores paired with four Cortex-A53
|
|
cores in a switched configuration. It features a GPU of the Maxwell
|
|
architecture with support for DX11, SM4, OpenGL 4.5, OpenGL ES 3.1
|
|
and providing 256 CUDA cores. It supports hardware-accelerated en-
|
|
and decoding of various video standards including H.265, H.264 and
|
|
VP8 at 4K resolution and up to 60 fps.
|
|
|
|
Besides the multimedia features it also comes with a variety of I/O
|
|
controllers, such as GPIO, I2C, SPI, SDHCI, PCIe, SATA and XHCI, to
|
|
name only a few.
