2023-08-11gpio: imx-scu: Use ARRAY_SIZE for array lengthRajeshwar R Shinde1-1/+2
Use of macro ARRAY_SIZE to calculate array size minimizes the redundant code and improves code reusability. This fixes warnings reported by Coccinelle: drivers/gpio/gpio-imx-scu.c:106:32-33: WARNING: Use ARRAY_SIZE Signed-off-by: Rajeshwar R Shinde <coolrrsh@gmail.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
2023-03-06gpio: remove MODULE_LICENSE in non-modulesNick Alcock1-1/+0
Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

2022-08-31gpio: imx-scu: add imx-scu GPIO driverShenwei Wang1-0/+139
The SCU firmware on i.MX8 platforms provides a set of APIs to control the GPIO PINs on the SCU domain. This patch implements the standard GPIO driver interface to access those PINs on the SCU domain over the SCU APIs.
