* reset: uniphier-glue: Fix possible null-ptr-derefHui Tang2023-01-031-3/+1
| | | | | | | | | | | It will cause null-ptr-deref when resource_size(res) invoked, if platform_get_resource() returns NULL.

* reset: uniphier-glue: Use devm_add_action_or_reset()Philipp Zabel2022-05-031-26/+24
| | | | | | | | | | | Slightly simplify uniphier_glue_reset_probe() and drop uniphier_glue_reset_remove() by using devm_add_action_or_reset() for clock and reset cleanup.

* reset: uniphier-glue: Use reset_control_bulk APIPhilipp Zabel2022-05-031-19/+14
| | | | | | | | | | This driver already uses the clk_bulk API. Simplify the driver by using the reset_control_bulk API as well.

* reset: Move reset-simple header out of drivers/resetMaxime Ripard2020-06-161-2/+1
| | | | | | | | | | The reset-simple code can be useful for drivers outside of drivers/reset that have a few reset controls as part of their features. Let's move it to include/linux/reset.

* reset: uniphier-usb3: Rename to reset-uniphier-glueKunihiko Hayashi2019-01-071-0/+171
This driver works for controlling the reset lines including USB3 glue layer, however, this can be applied to other glue layers. Now this patch renames the driver from "reset-uniphier-usb3" to "reset-uniphier-glue". At the same time, this changes CONFIG_RESET_UNIPHIER_USB3 to CONFIG_RESET_UNIPHIER_GLUE.
