staging: fbtft: Stop using BL_CORE_DRIVER1

2018-04-30T12:25:14+00:00

Leaking driver internal tracking into the already massively confusing
backlight power tracking is really confusing.

Luckily we have already a drvdata structure, so fixing this is really
easy.

staging: fbtft: Add TODO file with GPIO work item

2018-04-23T12:36:10+00:00

To make sure that these drivers do not leave staging before they
are properly converted to use the new GPIO descriptor API, create
the TODO file with this work item.

staging: fbtft: remove unused FB_TFT_SSD1325 kconfig

2018-01-25T12:10:39+00:00

Since nothing builds/depends on FB_TFT_SSD1325, we could remove it.

staging: fbtft: remove redundant license text

2018-01-15T15:03:46+00:00

Now that the SPDX tag is in all fbtft files, that identifies the license
in a specific and legally-defined manner.  So the extra GPL text wording
can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.

staging: fbtft: add SPDX identifiers

2018-01-15T15:03:46+00:00

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Fix up the all of the staging fbtft drivers to have a proper SPDX
identifier, based on the license text in the file itself.  The SPDX
identifier is a legally binding shorthand, which can be used instead of
the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

drivers/fbtft: Remove unnecessary braces from if/else

2018-01-08T15:03:45+00:00

The Linux kernel coding style states that braces should only be used
when necessary.

This fixes the checkpatch warning
