Introduce enum reset_control_flags and replace the list of boolean parameters to the internal reset_control_get functions with a single flags parameter, before adding more boolean options. The separate boolean parameters have been shown to be error prone in the past. See for example commit a57f68ddc886 ("reset: Fix devm bulk optional exclusive control getter"). Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> --- Changes in v2: - Clear RESET_CONTROL_FLAGS_BIT_OPTIONAL out of flags. - Check flags in __of_reset_control_get(). - Fix devm_reset_control_array_get() documentation. --- drivers/reset/core.c | 71 ++++++++++++---------- include/linux/reset.h | 161 +++++++++++++++++++++++++++++++------------------- 2 files changed, 139 insertions(+), 93 deletions(-)
