* [PATCHv2 04/27] OMAPDSS: add 'label' support for DT
From: Tomi Valkeinen @ 2013-12-16 14:56 UTC (permalink / raw)
To: linux-omap, linux-fbdev, devicetree; +Cc: Tomi Valkeinen
In-Reply-To: <1387205794-32246-1-git-send-email-tomi.valkeinen@ti.com>
Add support to get the label (i.e. a "nickname") for a display from the
DT data. If there is no label defined, use the display's alias (e.g.
'display0') as a name.

* [PATCHv2 05/27] OMAPDSS: get dssdev->alias from DT alias
From: Tomi Valkeinen @ 2013-12-16 14:56 UTC (permalink / raw)
To: linux-omap, linux-fbdev, devicetree; +Cc: Tomi Valkeinen
In-Reply-To: <1387205794-32246-1-git-send-email-tomi.valkeinen@ti.com>
We currently create a "displayX" style alias name for all displays,
using a number that is incremented for each registered display. With the
new DSS device model there is no clear order in which the displays are
registered, and thus the numbering is somewhat random.
This patch improves the behavior for DT case so that if the displays
have been assigned DT aliases, those aliases will be used as DSS
aliases.
This means that "display0" is always the one specified in the DT alias,
and thus display0 can be used as default display in case the user didn't
specify a default display.

* compare the given display name to the display's alias
* if no display name is given, look for "display0" DT alias

* [PATCHv2 12/27] OMAPDSS: Add DT support to DSI
From: Tomi Valkeinen @ 2013-12-16 14:56 UTC (permalink / raw)
To: linux-omap, linux-fbdev, devicetree; +Cc: Tomi Valkeinen
In-Reply-To: <1387205794-32246-1-git-send-email-tomi.valkeinen@ti.com>
Add the code to make the DSI driver work with device tree on OMAP3 and
OMAP4.
A minor hack is needed at the moment in the DSI driver: the DSS driver
needs to know the ID number of a DSI device, as clocks are routed in
different ways to the DSI devices. At the moment we don't have any
proper way to manage this, so this patchs adds a simple lookup table
that is used to deduce the ID from the DSI device's base address.

This is a test for Overo with Palo43 expansion, _not_ Tobi. Palo43
doesn't have a dts, but seems to work ok with omap3-tobi.dts, so I used
it as a test.
Not to be merged.

* [PATCH v3] if xen_platform_pci=0 is set don't blow up.
From: Konrad Rzeszutek Wilk @ 2013-12-16 15:04 UTC (permalink / raw)
To: axboe, stefano.stabellini, ian.campbell, xen-devel, linux-kernel,
boris.ostrovsky, david.vrabel, leosilva, ashley, peterhuewe, mail,
tpmdd, dmitry.torokhov, bhelgaas, plagnioj, tomi.valkeinen,
tpmdd-devel, linux-input, netdev, linux-pci, linux-fbdev
The first patch:
[PATCH v3 1/2] xen/pvhvm: If xen_platform_pci=0 is set don't blow up
I would like to commit to stable as it is fixing an eggregious bug -
where we blow up if the guest config has: "xen_platform_pci=0" setup.
This bug has been in existence for years and it is time to stamp it out.
The second patch is a cleanup - not a stable candidate.
It touches all of the Xen frontend drivers and adds the logic of:
"if user disabled us, don't init" - with variations. As you can
specify exactly which ones you want to init and which ones
not (Linux runtime parameter 'xen_emul_unplug'). But for the majority
of drivers - it is just an on/off switch.
Since it touches a lot of maintainers I figured I would send it
to Linus on Wednesday or Thursday.
Thank you!
