[PATCH v3 0/2] ARM: shmobile: r8a7790: add thermal driver support

[Simon Horman]

This short series enables the thermal driver on the r8a7790 SoC
and thus the lager board.

It is based on renesas-next-20130620

v3
* Correct title of clocks patch to refer to r8a7790

v2
* Add clocks patch

Unfortunately this patch conflicts with "ARM: shmobile: r8a7790: Wait for
status on all MSTP clocks" which I have queued up as a fix for v3.14.

As this patch will be submitted for inclusion on v3.15 it will be in a
branch based on v3.14-rc1 which I expect to include (""ARM: shmobile:
r8a7790: Wait for status on all MSTP clocks").

Rather than risk messing up doing the non-trivial rebase of this
patch myself I have dropped this patch. Could you please rebase it
on top of the latest devel tag of the renesas tree, currently
renesas-devel-v3.13-rc7-20140108.

If you don't mind, I'll split out and bundle all the clock-related patches up in one series.
This includes VIN, USB host, SATA clocks.
Clocks do not depend on anything else and can be applied with no harm even if the
driver that needs them is still pending. Besides, it should minimize possible conflicts.

Thanks,
Val.

[PATCH v3 0/2] ARM: shmobile: r8a7790: add for USB-DMAC

[Yoshihiro Shimoda]

This patch set is based on renesas.git / renesas-devel-20150507-v4.1-rc1
tag. (commit id = c3059b3fff4ed6568783fdabdee1d62a55aa469c)

This patch set is related to the usb-dmac driver and renesas_usbhs driver.
Almost all patches for the drivers have been merged in Linus tree.
And a fixed patch for renesas_usbhs driver have beed merged in the subsystem:
