I don't have corresponing hardware nor documentation. But it seems to be a copy-paste mistake from early driver development that was not fixed later, maybe because the original developer had only a board with port LEDs in LED group 0... --- drivers/net/dsa/realtek/rtl8366rb-leds.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/net/dsa/realtek/rtl8366rb-leds.c b/drivers/net/dsa/realtek/rtl8366rb-leds.c index 99c890681ae6..509ffd3f8db5 100644 --- a/drivers/net/dsa/realtek/rtl8366rb-leds.c +++ b/drivers/net/dsa/realtek/rtl8366rb-leds.c @@ -12,11 +12,11 @@ static inline u32 rtl8366rb_led_group_port_mask(u8 led_group, u8 port) case 0: return FIELD_PREP(RTL8366RB_LED_0_X_CTRL_MASK, BIT(port)); case 1: - return FIELD_PREP(RTL8366RB_LED_0_X_CTRL_MASK, BIT(port)); + return FIELD_PREP(RTL8366RB_LED_X_1_CTRL_MASK, BIT(port)); case 2: - return FIELD_PREP(RTL8366RB_LED_0_X_CTRL_MASK, BIT(port)); + return FIELD_PREP(RTL8366RB_LED_2_X_CTRL_MASK, BIT(port)); case 3: - return FIELD_PREP(RTL8366RB_LED_0_X_CTRL_MASK, BIT(port)); + return FIELD_PREP(RTL8366RB_LED_X_3_CTRL_MASK, BIT(port)); default: return 0; } -- 2.52.0
