PATCH 1/1 ARM: dts: BCM5301X: Relicense most DTS files to the GPL 2.0+ / MIT

From: Rafa? Mi?ecki <[email protected]>

These files were created and ever touched by a group of three people
only: Dan, Hauke and me. They were licensed under GNU/GPL or ISC.

Introducing and discussing SPDX-License-Identifier resulted in a conclusion that ISC is a not recommended license (see also a license-rules.rst). Moveover an old e-mail from Alan Cox was pointed which explained that dual licensing is a safer solution than depending on a common compatibility belief.

This commit switches most of BCM5301X DTS files to dual licensing using:
1) GPL 2.0+ to make sure they are compatible with Linux kernel
2) MIT to allow sharing with more permissive projects
Both licenses belong to the preferred ones (see LICENSES/preferred/).

An attempt to relicense remaining files will be made separately and will require approve from more/other developers.

Many thanks for doing this, it makes the license "confusion" a bit less now :)

Quoted 16 lines · Rafał Miłecki

From: Rafał Miłecki <[email protected]>

These files were created and ever touched by a group of three people
only: Dan, Hauke and me. They were licensed under GNU/GPL or ISC.

Introducing and discussing SPDX-License-Identifier resulted in a conclusion that ISC is a not recommended license (see also a license-rules.rst). Moveover an old e-mail from Alan Cox was pointed which explained that dual licensing is a safer solution than depending on a common compatibility belief.

This commit switches most of BCM5301X DTS files to dual licensing using:
1) GPL 2.0+ to make sure they are compatible with Linux kernel
2) MIT to allow sharing with more permissive projects Both licenses belong to the preferred ones (see LICENSES/preferred/).

Quoted 4 lines

An attempt to relicense remaining files will be made separately and will require approve from more/other developers.

re-sent without footer

In reply to Rafał Miłecki
Quoted 16 lines · Rafa? Mi?ecki

From: Rafa? Mi?ecki <[email protected]>

These files were created and ever touched by a group of three people
only: Dan, Hauke and me. They were licensed under GNU/GPL or ISC.

Introducing and discussing SPDX-License-Identifier resulted in a conclusion that ISC is a not recommended license (see also a license-rules.rst). Moveover an old e-mail from Alan Cox was pointed which explained that dual licensing is a safer solution than depending on a common compatibility belief.

This commit switches most of BCM5301X DTS files to dual licensing using:
1) GPL 2.0+ to make sure they are compatible with Linux kernel
2) MIT to allow sharing with more permissive projects Both licenses belong to the preferred ones (see LICENSES/preferred/).

Quoted 4 lines

An attempt to relicense remaining files will be made separately and will require approve from more/other developers.

From: Rafa? Mi?ecki <[email protected]>

These files were created and ever touched by a group of three people
only: Dan, Hauke and me. They were licensed under GNU/GPL or ISC.

Introducing and discussing SPDX-License-Identifier resulted in a conclusion that ISC is a not recommended license (see also a license-rules.rst). Moveover an old e-mail from Alan Cox was pointed which explained that dual licensing is a safer solution than depending on a common compatibility belief.

This commit switches most of BCM5301X DTS files to dual licensing using:
1) GPL 2.0+ to make sure they are compatible with Linux kernel
2) MIT to allow sharing with more permissive projects Both licenses belong to the preferred ones (see LICENSES/preferred/).

Quoted 4 lines

An attempt to relicense remaining files will be made separately and will require approve from more/other developers.

re-sent without footer and using text/plain

From: Rafa? Mi?ecki <[email protected]>

These files were created and ever touched by a group of three people
only: Dan, Hauke and me. They were licensed under GNU/GPL or ISC.

Introducing and discussing SPDX-License-Identifier resulted in a conclusion that ISC is a not recommended license (see also a license-rules.rst). Moveover an old e-mail from Alan Cox was pointed which explained that dual licensing is a safer solution than depending on a common compatibility belief.

This commit switches most of BCM5301X DTS files to dual licensing using:
1) GPL 2.0+ to make sure they are compatible with Linux kernel
2) MIT to allow sharing with more permissive projects
Both licenses belong to the preferred ones (see LICENSES/preferred/).

Quoted 5 lines

An attempt to relicense remaining files will be made separately and will require approve from more/other developers.

Applied to devicetree/next, thanks!
