* [PATCHv3 08/41] OMAPDSS: Improve regulator names for DT
From: Tomi Valkeinen @ 2014-01-21 10:56 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1390301833-24944-1-git-send-email-tomi.valkeinen@ti.com>
The regulator names used for DSS components are somewhat ugly for DT
use. As we're just adding DT support, it's simple to change the
regulator names.
This patch makes the DSS driver get the regulators with somewhat cleaner
names. For example, this allows us to define HDMI's VDDA regulator in
the DT data as:
vdda-supply = <...>;
instead of
vdda_hdmi_dac-supply = <...>;
The code also still tries to get the regulators with the old names, if
the regulator_get with the new names fail. This keep backward
compatibility, and can be removed after we have moved to DT.

* [PATCHv3 09/41] OMAPDSS: Add DT support to DSS
From: Tomi Valkeinen @ 2014-01-21 10:56 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1390301833-24944-1-git-send-email-tomi.valkeinen@ti.com>
Add DT support for DSS. Contrary to the non-DT version, the DSS in DT
mode contains DPI and SDI outputs, which better reflects the hardware.
The non-DT code will be removed after all boards have been converted to
DT, so there's no need to change the non-DT code to act the same way.
The code for DPI and SDI needs to be refined later to make it possible
to add multiple DPI ports. For now, handling just a single DPI port is
enough for all the boards.

* [PATCHv3 12/41] OMAPDSS: Add DT support to VENC
From: Tomi Valkeinen @ 2014-01-21 10:56 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1390301833-24944-1-git-send-email-tomi.valkeinen@ti.com>
Add DT support to VENC.
In contrast to non-DT version, the DT version gets the invert-polarity
and connector type via venc's endpoint, not from the connector.

* [PATCHv3 13/41] OMAPDSS: Add DT support to DSI
From: Tomi Valkeinen @ 2014-01-21 10:56 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1390301833-24944-1-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.

* [PATCHv3 24/41] ARM: omap4.dtsi: add omapdss information
From: Tomi Valkeinen @ 2014-01-21 10:56 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1390301833-24944-1-git-send-email-tomi.valkeinen@ti.com>
Add DT data for OMAP4 display subsystem, which contains the following
blocks:
dss - the wrapper/glue for the display modules
dispc - display controller
dsi - MIPI DSI encoder (two independent modules)
rfbi - MIPI DBI encoder
venc - analog TV encoder
hdmi - HDMI encoder

* [PATCHv3 31/41] OMAPDSS: remove DT hacks for regulators
From: Tomi Valkeinen @ 2014-01-21 10:57 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1390301833-24944-1-git-send-email-tomi.valkeinen@ti.com>
For booting Panda and 4430SDP with DT, while DSS did not support DT, we
had to had small hacks in the omapdss driver to get the regulators. With
DT now supported in DSS, we can remove those hacks.
