Hi all,
This is yet another update on patchset, which enables HDMI support for
Exynos based platforms.
Beside DTS changes, this patchset adds parent domain support for Exynos
PM domains and add support for 'hdmi' clock directly to Exynos DRM mixer
driver.
The patchset is based on samsung/for-next branch and 'PM / Domains:
Export of_genpd_get_from_provider function' patch merged as commit
7496fcbe8a643097efc061160e1c3b65ee2fa350 to v3.19-rc4.
Regards
Marek Szyprowski
Changelog:
v5:
- fixed error value for clk_get() in mixer patch
- rebased onto samsung/for-next branch
v4: (http://www.spinics.net/lists/linux-samsung-soc/msg41375.html)
- added patches, which add 'hdmi' clock handling to mixed block, this
finally solves the initialization related issues, thanks for Tobias
Jakobi for testing
- added acks/reviewed/tested by tags
v3: (http://www.spinics.net/lists/linux-samsung-soc/msg41020.html)
- added a note on defining subdomains to generic PM domain binding
documentation (requested by Ulf Hansson)
v2: (http://www.spinics.net/lists/linux-samsung-soc/msg40980.html)
- rewrote subdomains patch according to suggestions from Geert
Uytterhoeven and Amit Daniel Kachhap.
v1 resend: (http://www.spinics.net/lists/linux-samsung-soc/msg39428.html)
- added handling of generic 'power-domains' binding in subdomains
v1: (http://www.spinics.net/lists/linux-samsung-soc/msg38914.html)
- resolved power domain on/off issue with 'clk: samsung: exynos4: set
parent of mixer gate clock to hdmi' patch
v0: (http://www.spinics.net/lists/linux-samsung-soc/msg33498.html)
- first attempt, used 'always on' power domains hack

This patch adds support for making one power domain a sub-domain of
other domain. This is useful for modeling power dependences for devices
like TV Mixer or Camera ISP, which needs to have more than one power
domain enabled to be operational.

TV Mixer needs both TV and LCD0 domains enabled to be fully operational.
This dependency is modelled by making TV power domains a sub-domain of
LCD0 power domain.

Mixed block needs to control hdmi clock to properly perform power on/off
operation, so add 'hdmi' clock also to mixer nodes.

Mixed block needs to control hdmi clock to properly perform power on/off
operation, so add 'hdmi' clock also to mixer nodes.

Mixed need to have hdmi clock enabled to properly perform power on/off
sequences, so add handling of this clock directly to the mixer driver.
Dependency between hdmi clock and mixer module has been observed on
Exynos4 based boards.

I have no objection on this series, but just wondering my tree should be fine
without 9/9 drm patch and it will be handled for 3.20?
I'll take 1 to 8 patches once drm patch is landed for 3.20.
