This patch series updates the device tree vendor prefix for
Dialog Semiconductor.
Various methods are currently used throughout the kernel: 'diasemi',
'dialog' and 'dlg'. Others have also been suggested.
This patch set aims to consolidate the usage of the vendor prefix to
use a common standard. The prefix 'dlg' is used.
Here is my working for justifying this change:
./arch/arm/boot/dts/imx6qdl-phytec-pfla02.dtsi
Has the following entry:
compatible = "dialog,da9063";
However the DA9063 driver does not support device tree yet so
it would be safe to rename this.
./arch/arm/boot/dts/imx53-smd.dts
Has the following entry:
compatible = "dialog,da9053", "dialog,da9052";
However, the existing driver files for DA9053 define a different
compatible string with the "dlg" prefix. See the entries below.
None of these would have allowed the "dialog" prefix.
{ .compatible = "dlg,da9052", .data = &da9052_i2c_id[0] },
{ .compatible = "dlg,da9053-aa", .data = &da9052_i2c_id[1] },
{ .compatible = "dlg,da9053-ba", .data = &da9052_i2c_id[2] },
{ .compatible = "dlg,da9053-bb", .data = &da9052_i2c_id[3] },
{ .compatible = "dlg,da9053-bc", .data = &da9052_i2c_id[4] },
In this particular case the change for DA9053 did not match up
with the expected compatibility strings and therefore I have
retained the more general "dlg,da9053" because I do not know
which silicon variant (-aa, -ba, -bb, or -bc) is the correct
one to use.
./devicetree/bindings/i2c/trivial-devices.txt
Has the following entry:
dialog,da9053 DA9053: flexible system level PMIC with multicore support
Instead of depreciating this "dialog" line I am just replacing it
with a "dlg" because the existing driver DA9053 does not support
the dialog keyword.
./drivers/mfd/da9055-core.c
Has the following entries for the mfd cells
.of_compatible = "dialog,da9055-gpio", etc...
In this case, the driver does not actually pass in any platform data
to any of the mfd cells and so they are not actually used
yet in the driver. Nobody else references this information.
./devicetree/bindings/regulator/da9210.txt
Has the following two entries in the binding file:
- compatible: must be "diasemi,da9210"
compatible = "diasemi,da9210";
However the DA9210 driver does not support device tree.
./arch/arm/boot/dts/r8a7790-lager.dts
./arch/arm/boot/dts/r8a7791-koelsch.dts
These two files have the following entries:
compatible = "diasemi,da9210";
These both reference the "diasemi,da9210" but the device
driver does not support device tree
The remaining files in the kernel I have found correctly references
the driver files compatibility information and so did not need to
be changed.
./devicetree/bindings/mfd/da9052-i2c.txt
- compatible : Should be "dlg,da9052", "dlg,da9053-aa",
"dlg,da9053-ab", or "dlg,da9053-bb"
./devicetree/bindings/mfd/da9055.txt
compatible = "dlg,da9055-pmic";
./arch/arm/boot/dts/imx53-voipac-dmm-668.dtsi
compatible = "dlg,da9053-aa", "dlg,da9052";
./arch/arm/boot/dts/imx53-qsb.dts
compatible = "dlg,da9053-aa", "dlg,da9052";
./devicetree/bindings/sound/da9055.txt
- compatible: "dlg,da9055-codec"
compatible = "dlg,da9055-codec";
