2019-04-02staging: fbtft: fb_agm1264k-fl.c: Replace bit shifting with BIT macroPayal Kshirsagar
Challenge suggested by coccinelle. Prefer using BIT and replace bit shifting with the BIT(x) macro. Signed-off-by: Payal Kshirsagar <payal.s.kshirsagar.98@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2019-01-18Staging: fbtft: Switch to the gpio descriptor interfaceNishad Kamdar
This switches the fbtft driver to use GPIO descriptors rather than numerical gpios: Utilize the GPIO library's intrinsic handling of OF GPIOs and polarity. If the line is flagged active low, gpiolib will deal with this. Remove gpios from platform device structure. Neither assign statically numbers to gpios in platform device nor allow gpios to be parsed as module parameters.

2018-01-15staging: fbtft: remove redundant license textGreg Kroah-Hartman
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.

2018-01-15staging: fbtft: add SPDX identifiersGreg Kroah-Hartman
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.
