Pushing this patch myself as no one else did.

Please excuse if this is a duplicate, but I'm configuring a new mail tool and I don't think my other message got sent.
It is XM_A and XM_B that are odd-balls, so the correct code should be something like:
+ switch (get_board_revision()) { + case REVISION_XM_A: + case REVISION_XM_B: + twl4030_led_init(TWL4030_LED_LEDEN_LEDBON); /* LEDA signal set low */ + break; + default: + twl4030_led_init(TWL4030_LED_LEDEN_LEDAON | TWL4030_LED_LEDEN_LEDBON); + break;
}
Am I just too sleepy or the Subject doesn't correlate with what the patch does ...
My understanding of Subject is that it enables power on HUB ... USB HUB ? But the patch enables some LEDs ?
The LED drivers on the power management device (TWL4030-compatible) are used to enable the hub power.
I might be wrong.
