reset: fix linux/reset.h errors

2019-04-02T15:57:35Z

The header file uses errno constant(s) and the ERR_PTR() macro but does not #include the appropriate header files that provide those facilities, so add 2 header files to fix build errors.

reset: add acquired/released state for exclusive reset controls

2019-03-20T10:16:55Z

There are cases where a driver needs explicit control over a reset line that is exclusively conneted to its device, but this control has to be temporarily handed over to the power domain controller to handle reset requirements during power transitions. Allow multiple exclusive reset controls to be requested in 'released' state for the same physical reset line, only one of which can be acquired at the same time.

reset: Add reset_control_get_count()

2019-01-07T15:38:26Z

Currently the reset core has internal support for counting the number of resets for a device described in DT. Generalize this to devices using lookup resets, and export it for public use. This will be used by generic drivers that need to be sure a device is controlled by a single, dedicated reset line (e.g. vfio-platform).

reset: minimize the number of headers included from

2017-11-27T08:16:40Z

Commit 62e24c5775ec ("reset: add exported __reset_control_get, return NULL if optional") moved the dev->of_node reference to core.c, so does not need to know the members of struct device. Declaring device and device_node as structure is enough. is necessary for bool, true, and false. Signed-off-by: Masahiro Yamada Signed-off-by: Philipp Zabel
