Re: [PATCH v8 02/17] drm: bridge: analogix/dp: split exynos dp driver to bridge directory

Hi Heiko,

Thanks you for feedback, I do see some conflicts in Exynos Make/Kconfig
file [02/17] and dtsi file [07/17] when I try to apply this series on 4.4-rc1
branch.

Hmm... Due to I have update some patches to version 10 already, this
series may be become harder to reviewed, should I just send the whole
series out that update the version to v10.

Thanks
- Yakir

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 four hooks.
"analogix_dp_bind()" and "analogix_dp_unbind()"
"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 doesn't apply anymore to 4.4-rc due to other changes in there. The
exynos/Makefile is affected as well.
