reset: Fix potential use-after-free in __of_reset_control_get()

2019-11-25T08:53:42Z

[ Upstream commit b790c8ea5593d6dc3580adfad8e117eeb56af874 ] Calling of_node_put() decreases the reference count of a device tree object, and may free some data. However, the of_phandle_args structure embedding it is passed to reset_controller_dev.of_xlate() after that, so it may still be accessed. Move the call to of_node_put() down to fix this.

reset: make device_reset_optional() really optional

2018-12-08T12:05:08Z

commit 1554bbd4ad401b7f0f916c0891874111c10befe5 upstream. Commit bb475230b8e5 ("reset: make optional functions really optional") converted *_get_optional* functions, but device_reset_optional() was left behind. Convert it in the same way.

reset: add exported __reset_control_get, return NULL if optional

2018-12-08T12:05:08Z

commit 62e24c5775ecb387a3eb33701378ccfa6dbc98ee upstream. Rename the internal __reset_control_get/put functions to __reset_control_get/put_internal and add an exported __reset_control_get equivalent to __of_reset_control_get that takes a struct device parameter. This avoids the confusing call to __of_reset_control_get in the non-DT case and fixes the devm_reset_control_get_optional function to return NULL if RESET_CONTROLLER is enabled but dev->of_node == NULL.

commit 4891486fb2c80eaf3bb0f9eb065d15ecd357702f upstream. Commit "reset: make optional functions really optional" missed to adjust one check in reset_control_put, causing a NULL pointer access for optional resets.

reset: make optional functions really optional

2018-12-08T12:05:08Z

commit bb475230b8e59a547ab66ac3b02572df21a580e9 upstream. The *_get_optional_* functions weren't really optional so this patch makes them really optional. These *_get_optional_* functions will now return NULL instead of an error if no matching reset phandle is found in the DT, and all the reset_control_* functions now accept NULL rstc pointers.

reset: hi6220: Set module license so that it can be loaded

2018-11-10T15:42:47Z

[ Upstream commit 4497a224f759cd8350e07382307b55f870ef0df2 ] The hi6220_reset driver can be built as a standalone module yet it cannot be loaded because it depends on GPL exported symbols. Lets set the module license so that the module loads, and things like the on-board kirin drm starts working.

reset: uniphier: rename MIO reset to SD reset for Pro5, PXs2, LD20 SoCs

2016-10-22T09:31:42Z

I made a mistake as for naming for this block. The MIO block is not implemented for these 3 SoCs in the first place. The current naming will be a trouble if an SoC with both MIO and SD-ctrl blocks appear in the future. This driver has just been merged in the previous merge window. Rename it before the release.
