reset: lpc18xx: get rid of global variables for restart notifier

2016-03-30T13:42:07Z

Moving the notifier_block into the drivers priv struct allows us to retrive the priv struct with container_of and remove the global variables. Signed-off-by: Joachim Eastwood Signed-off-by: Philipp Zabel

reset: Add support for shared reset controls

2016-03-30T13:42:05Z

In some SoCs some hw-blocks share a reset control. Add support for this setup by adding new: reset_control_get_shared() devm_reset_control_get_shared() devm_reset_control_get_shared_by_index() methods to get a reset_control. Note that this patch omits adding of_ variants, if these are needed later they can be easily added. This patch also changes the behavior of the existing exclusive reset_control_get() variants, if these are now called more then once for the same reset_control they will return -EBUSY. To catch existing drivers triggering this error (there should not be any) a WARN_ON(1) is added in this path. When a reset_control is shared, the behavior of reset_control_assert / deassert is changed, for shared reset_controls these will work like the clock-enable/disable and regulator-on/off functions. They will keep a deassert_count, and only (re-)assert the reset after reset_control_assert has been called as many times as reset_control_deassert was called. Calling reset_control_assert without first calling reset_control_deassert is not allowed on a shared reset control. Calling reset_control_reset is also not allowed on a shared reset control.

reset: Share struct reset_control between reset_control_get calls

2016-03-30T13:42:03Z

Now that struct reset_control no longer stores the device pointer for the device calling reset_control_get we can share a single struct reset_control when multiple calls to reset_control_get are made for the same reset line (same id / index). This is a preparation patch for adding support for shared reset lines. Signed-off-by: Hans de Goede Signed-off-by: Philipp Zabel

reset: Make [of_]reset_control_get[_foo] functions wrappers

2016-03-30T13:42:01Z

With both the regular, _by_index and _optional variants we already have quite a few variants of [of_]reset_control_get[_foo], the upcoming addition of shared reset lines support makes this worse. This commit changes all the variants into wrappers around common core functions. For completeness sake this commit also adds a new devm_get_reset_control_by_index wrapper.
