The reset control API has two modes: exclusive access, where the driver expects to have full and immediate control over the state of the reset line, and shared (clock-like) access, where drivers only request reset deassertion while active, but don't care about the state of the reset line while inactive.
Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting reset lines") started to transition the reset control request API calls to explicitly state whether the driver needs exclusive or shared reset control behavior.
This series converts all drivers that currently implicitly request exclusive reset controls to the corresponding explicit API call. It is, for the most part, generated from the following semantic patch:
@@ expression rstc, dev, id; @@ -rstc = reset_control_get(dev, id); +rstc = reset_control_get_exclusive(dev, id); @@ expression rstc, dev, id; @@ -rstc = reset_control_get_optional(dev, id); +rstc = reset_control_get_optional_exclusive(dev, id); @@ expression rstc, node, id; @@ -rstc = of_reset_control_get(node, id); +rstc = of_reset_control_get_exclusive(node, id); @@ expression rstc, node, index; @@ -rstc = of_reset_control_get_by_index(node, index); +rstc = of_reset_control_get_exclusive_by_index(node, index); @@ expression rstc, dev, id; @@ -rstc = devm_reset_control_get(dev, id); +rstc = devm_reset_control_get_exclusive(dev, id); @@ expression rstc, dev, id; @@ -rstc = devm_reset_control_get_optional(dev, id); +rstc = devm_reset_control_get_optional_exclusive(dev, id); @@ expression rstc, dev, index; @@ -rstc = devm_reset_control_get_by_index(dev, index); +rstc = devm_reset_control_get_exclusive_by_index(dev, index);
After all driver patches are applied, the temporary transition helpers can be removed.
