Commit aeefb36832 ("drm/exynos: gsc: add device tree support and remove
usage of static mappings") made the DRM_EXYNOS_GSC Kconfig symbol to only
be selectable if the exynos-gsc V4L2 driver isn't enabled, since both use
the same HW IP block.
But added the dependency as depends on !VIDEO_SAMSUNG_EXYNOS_GSC which is
not correct since Kconfig expressions are not boolean but tristate. So it
will only evaluate to 'n' if VIDEO_SAMSUNG_EXYNOS_GSC=y but will evaluate
to 'm' if VIDEO_SAMSUNG_EXYNOS_GSC=m.
This means that both the V4L2 and DRM drivers can be enabled if the former
is enabled as a module, which isn't what we want since otherwise 2 drivers
could attempt to use the hardware at the same time.

This pull request adds to the rework patch series for IOMMU
integration to support ARM64bit architecture with DMA-IOMMU

With this patch series, Exynos DRM works well on Exynos5433 SoC
with IOMMU enabled.

drm/exynos: iommu: add support for ARM64 specific code for IOMMU glue

Split the dp core driver from exynos directory to bridge directory,
and rename the core driver to analogix_dp_*, rename the platform
code to exynos_dp.
Beside the new analogix_dp driver would export six hooks.
"analogix_dp_bind()" and "analogix_dp_unbind()"
"analogix_dp_suspned()" and "analogix_dp_resume()"
"analogix_dp_detect()" and "analogix_dp_get_modes()"
The bind/unbind symbols is used for analogix platform driver to connect
with analogix_dp core driver. And the detect/get_modes is used for analogix
platform driver to init the connector.
They reason why connector need register in helper driver is rockchip drm
haven't implement the atomic API, but Exynos drm have implement it, so
there would need two different connector helper functions, that's why we
leave the connector register in helper driver.

This is because ptn3460_init can't be implemented in a module while
its caller is built into the kernel. So add the proper dependency in
Kconfig so that the above can't happen.
I moved DRM_PTN3460 earlier in Kconfig, next to the I2C helper module

the Exynos-specific section.
IMHO the proper way to solve the problem would be to turn ptn3460 into
a clean I2C driver, similar to the other I2C helper chip drivers. It's
the only way to not sink into impossible-to-guess dependencies. Then
ptn3460 could even be moved together with the other I2C helper chip

Select the new option in all drivers for now, so this shouldn't result
in any change. Drivers need some work anyway to make fbdev support
optional (if they have it implemented, that is), so the recommended
way to expose this is by adding per-driver options. At least as long
as most drivers don't support disabling the fbdev support.

This patch adds OF initialization support for the FIMC driver.
The binding documentation can be found at Documentation/devicetree/
bindings/media/samsung-fimc.txt.
The syscon regmap interface is used to serialize access to the
shared CAMBLK registers from within the V4L2 FIMC-IS and the DRM
FIMC drivers. The DRM driver uses this interface for setting up
the FIFO data link between FIMD and FIMC IP blocks, while the V4L2
one for setting up a data link between the camera ISP and FIMC for
camera capture. The CAMBLK registers are not accessed any more
through a statically mapped IO. Synchronized access to these
registers is required for simultaneous operation of the camera
ISP and the DRM IPP on Exynos4x12.
The driver data and driver_ids static data structures are removed
since Exynos4 is going to be a dt-only platform and there is
currently no board file in mainline that defines platform data
for the FIMC IPP, i.e. uses it.
Camera input signal polarities are not currently parsed from the

GSC is stand for General SCaler and supports the following features:
- image scaler/rotator/crop/flip/csc and input/output DMA operations.
- image rotation and image effect functions.
- writeback and display output operations.
- M2M operation to crop, scale, rotation and csc.
The below is GSC hardware path:
Memory------->GSC------>Memory
FIMD--------->GSC------>HDMI
FIMD--------->GSC------>Memory
Memory------->GSC------>FIMD, Mixer
This driver is registered to IPP subsystem framework to be used by user side
and user can control the GSC hardware through some interfaces of IPP subsystem
framework.
Changelog v1 ~ v5:
- added comments, code fixups and cleanups.

This patch adds IPP subsystem-based rotator driver.
And Rotator supports the following features.
- Image crop operation support.
- Rotate operation support to 90, 180 or 270 degree.
- Flip operation support to vertical, horizontal or both.
. as limitaions, the pixel format to source buffer should be
same as the one to destination buffer and no scaler.
This driver is registered to IPP subsystem framework to be used by user side
and user can control the Rotator hardware through some interfaces of IPP
subsystem framework.
Changelog v6:
- fix build warning.
Changelog v1 ~ v5:
- added comments, code fixups and cleanups.
