[PATCH 00/11] Exynos7: Adding USB 3.0 support

[PATCH 00/11] Exynos7: Adding USB 3.0 support

[Vivek Gautam]

The series has dependency on
a) "[PATCH v7 0/7] Enable support for Samsung Exynos7 SoC"
   http://www.spinics.net/lists/linux-samsung-soc/msg38734.html
b) "[GIT PULL] Samsung clock changes for 3.19" - specifically the clock dt
   bindings header.
   http://comments.gmane.org/gmane.linux.kernel.samsung-soc/39142
c) "tty: serial: samsung: Clean-up selection of number of available UARTs"
   http://www.spinics.net/lists/linux-samsung-soc/msg37418.html
d) "dts, kbuild: Implement support for dtb vendor subdirs"(merged in linux-next)
   https://lkml.org/lkml/2014/10/21/654
e) "Samsung pinctrl patches for v3.19"
   http://www.spinics.net/lists/linux-samsung-soc/msg38744.html

Tested on Exynos7-espresso board with 3.18-rc5 and above dependencies.

Clubbing the pinctrl, clk, and usb driver changes alongwith the dt changes
together in this series only so as to avoid having 'n' number of dependencies.

The USB driver patches in this series were part of [1] sent earlier.

Looks like you are just trying to touch pin banks only related to USB
stuffs, but as this patch does not have any dependencies on other
patches in this series, will you consider adding other pin banks of
BUS1, just for completeness of BUS1 pin-controller.

True, this just touches the USB related pinctrl.
Will add the rest pin banks of BUS1 for completeness.
Thanks for pointing out. :-)

If the change looks good, will it be possible to pick it fo 3.19-rc1 ?
That will really help enabling USB IP on exynos7.

As you know the Exynos driver has a maintainer, Tomasz Figa, I will not
merge patches without his ACK.

Apart from that, there are *again* a lot of Exynos patches flying around and
I start to loose track of them. If they do not apply together and start to
conflict I will just ask Tomasz to stack them and provide a pull request
again.

Yours,
Linus Walleij

True, this merge cycle has surely got number of exynos7 related
patches in flight,
which are difficult to keep track of.

I will probably not take any more Exynos patches for this merge cycle and
ask Tomasz to queue the Exynos pinctrl patches for v3.20 after v3.19
merge cycle is complete, so make sure to include Tomasz on reviews.

Tomasz: OK?

I have missed this with previous patch, but DT bindings documentation
should list all aliases for all supported compatible strings, because
they are required for correct operation. There is a small section
about aliases in [1] already, so please add there information about
aliases for Exynos7 pin controllers along with their names, e.g.

Aliases for controllers compatible with "samsung,exynos7-pinctrl":
 - pinctrl0: pin controller of ALIVE block,
 - pinctrl1: pin controller of BUS0 block,
 [...]
 - pinctrl8: pin controller of BUS1 block.

[1] Documentation/devicetree/bindings/pinctrl/samsung-pinctrl.txt

I guess you can do this in separate patch or respin this one with this added.

Best regards,
Tomasz

Sure, i will add the aliases in a separate patch.
I missed to update the patch in this cycle :-(
So we can queue up the reworked version for 3.20.

[PATCH 02/11] dwc3: exynos: Remove local variable for clock from probe

There's no need to keep one local variable for clock, and
then assign the same to 'clk' member of dwc3_exynos.
Just cleaning it up.

Exynos7 SoC has now separate gate control for 125MHz pipe3 phy

Additionally, separate gate control is available for the clock

So get the same and control in the phy-exynos5-usbdrd driver.

[PATCH 06/11] phy: exynos5-usbdrd: Add facility for VBUS-BOOST-5V supply

[Vivek Gautam]

Some Exynos boards have a separate regulator controlling a
Boost 5V supply which goes as input for VBUS regulator.
So adding a control for the same in driver, to enable
vbus supply on the port.

[PATCH 07/11] phy: exynos7-usbdrd: Update dependency for ARCH_EXYNOS

[Vivek Gautam]

This PHY controller is also present on Exynos7 platform
in arch-exynos family.
So PHY_EXYNOS5_USBDRD should now depend on ARCH_EXYNOS.

You too may want to pick the sole clock driver patch in this series
for 3.19 ? :-)
"clk: exynos7: Add required clock tree for USB"

Please let me know if the merge window is still open on your side so
that you can
pick this patch.

My apologies, it seems I have missed this patch. :/
Feel free to ping me off the list in future if there is no response
for more than week.
I queued this patch now for 3.20.  I'm putting all the exynos7 clk
patches on a separate branch which could then be pulled into samsung
arm tree for the dependant dts changes.
