The current reset framework API does not allow to release what is done by reset_control_reset(), IOW decrement triggered_count. Add the new reset_control_rearm() call to do so. When reset_control_reset() has been called once, the counter triggered_count, in the reset framework, is incremented i.e the resource under the reset is in-use and the reset should not be done again. reset_control_rearm() would be the way to state that the resource is no longer used and, that from the caller's perspective, the reset can be fired again if necessary.

2020-01-02reset: Align logic and flow in managed helpersGeert Uytterhoeven1-16/+17
__devm_reset_control_get() and devm_reset_control_array_get() are very similar, but they do not look similar, due to inverted logic. Make them more similar, following the "bail out early" paradigm. Adjust the logic and flow in devm_reset_controller_register() to match the two other functions.

2019-12-24reset: reset-scmi: Match scmi device by both name and protocol idSudeep Holla1-1/+1
The scmi bus now has support to match the driver with devices not only based on their protocol id but also based on their device name if one is available. This was added to cater the need to support multiple devices and drivers for the same protocol. Let us add the name "reset" to scmi_device_id table in the driver so that in matches only with device with the same name and protocol id SCMI_PROTOCOL_RESET.

2019-12-10reset: Do not register resource data for missing resetsGeert Uytterhoeven1-2/+2
When an optional reset is not present, __devm_reset_control_get() and devm_reset_control_array_get() still register resource data to release the non-existing reset on cleanup, which is futile. Fix this by skipping NULL reset control pointers. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

2019-12-10reset: brcmstb: Remove resource checksFlorian Fainelli1-6/+0
The use of IS_ALIGNED() is incorrect, the typical resource we pass looks like this: start: 0x8404318, size: 0x30. When using IS_ALIGNED() we will get the following 0x8404318 & (0x18 - 1) = 0x10 which is definitively not equal to 0, same goes with the size. These two checks would make the driver fail probing. Remove the resource checks, since there should be no constraint on the base addresse or size.
