[PATCH v3 0/9] ARM: dts: exynos: add support for hdmi subsystem

[Rahul Sharma]

Common properties for I2C and Hdmi Subsystem is moved to exynos5
dtsi file. It also adds Device tree nodes and clocks information
for exynos5420 and exynos5250 SoCs. It adds pinctrl node for hdmi
hpd gpio and update binding documents.

This set is based on kukjin's for-next branch at
http://git.kernel.org/cgit/linux/kernel/git/kgene/linux-samsung.git.

v3:
1) Rebase to kgene for-next based on 3.11-rc1.
2) Changes clock numbers as per updated clocks file for
exyno5250 and exynos5420.
3) Dropped Sachin patch as already got merged.

v2:
1) Added patch for moving common i2c properties to exynos5.dtsi
2) Added patch for moving common hdmi, mixer properties to exynos5.dtsi
3) moved hpd pinctrl node to board file.
4) Added Sachin's patch to update binding document for hdmi with hpd
information.

[PATCH v3 2/9] ARM: dts: exynos5250: add clocks to hdmi dt node

[Rahul Sharma]

Fix wrong clock numbers in hdmi dt node. Removed hdmiphy
clock which was a dummy clock earlier and not required now.
Also added mux clock to change the clock parent.

NAK, there are 8 I2C channels with different address on upcoming exynos5 so
this change is not acceptable. Note please check at least upcoming SoC
before making common something if possible.

NAK, again because of same reason with previous my comments. Note, different
addresses and IRQ# on upcoming exynos5 SoC.

See my comments about making common stuff for exynos5 SoCs.

And please don't use title like following,

'ARM: dts: exynos0000: ....'.

Because the relatively long prefix of title can cover _real_ title, So just
'ARM: dts: .... in exynos000' is better.

One more, devicetree(at)vger.kernel.org is right for dt ml.

I agree.

Well, I tend to disagree on this. The ARM: dts: <platform name>: prefix is 
commonly used in arch/arm/boot/dts (see git log --oneline 
arch/arm/boot/dts).

As long as we don't cross the ~75 characters boundary in patch subject, I 
don't think this is any problem.

+1

Also it is nice to Cc the device tree maintainers.

Hmm...it is not entirely true...

Let's see.

If we use the 'platform name' in prefixe for dt file,

"ARM: dts: exynos0000: add support for something"
or
"ARM: dts: universal_c210: add support for something"
or
"ARM: dts: exynos0000-pinctrl: add support for something"
...
most of them should spend over half of 75 characters as a prefix 
including 'add support for' in subject and in addition, there is '[PATCH 
v0 00/00]' in the email subject.

(+ Russell)

I remember there were discussions about subject and at that time the 
result was that keyword should be shown ahead as possible in subject. 
But we are still using too long word as a prefix...

One more note, even my e-mail client shows just 40~50 characters for 
subject because of relatively not big enough resolution and pre-read 
window and so on ;)
