reset: make device_reset_optional() really optional

2018-12-08T12:05:08+00:00

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

2018-12-08T12:05:08+00:00

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.

reset: core: fix reset_control_put

2018-12-08T12:05:08+00:00

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

2018-12-08T12:05:08+00:00

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

2018-11-10T15:42:47+00:00

[ 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.

If STATUS_SET was not set, ti_syscon_reset_status would always return 0

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

2016-10-22T09:31:42+00:00

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.
