Since v3.10, changes to 'enum pin_config_param', PIN_CONFIG_BIAS_PULL_(UP/DOWN) no longer map 1-to-1 with the expected values in devicetree. This patch adds a small translation between the devicetree values (0..2) and the enum pin_config_param equivalent values. Signed-off-by: Tony Prisk --- v2: Minor change in commit message to indicate time since problem occurred. Change assigned variable to configs[0] rather than reassigning to pull. Add a default case to the switch to prevent static checker errors. drivers/pinctrl/vt8500/pinctrl-wmt.c | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) diff --git a/drivers/pinctrl/vt8500/pinctrl-wmt.c b/drivers/pinctrl/vt8500/pinctrl-wmt.c index 39aec08..25ab2ee 100644 --- a/drivers/pinctrl/vt8500/pinctrl-wmt.c +++ b/drivers/pinctrl/vt8500/pinctrl-wmt.c @@ -276,7 +276,20 @@ static int wmt_pctl_dt_node_to_map_pull(struct wmt_pinctrl_data *data, if (!configs) return -ENOMEM; - configs[0] = pull; + switch (pull) { + case 0: + configs[0] = PIN_CONFIG_BIAS_DISABLE; + break; + case 1: + configs[0] = PIN_CONFIG_BIAS_PULL_DOWN; + break; + case 2: + configs[0] = PIN_CONFIG_BIAS_PULL_UP; + break; + default: + configs[0] = PIN_CONFIG_BIAS_DISABLE; + dev_err(data->dev, "invalid pull state %d - disabling\n", pull); + } map->type = PIN_MAP_TYPE_CONFIGS_PIN; map->data.configs.group_or_pin = data->groups[group];
