+Subject: [PATCH V2] USB: bcma: switch to GPIO descriptor for power control
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+So far we were using simple (legacy) GPIO functions & some poor logic to
+control power. It got many drawbacks: we were ignoring OF flags
+(GPIO_ACTIVE_LOW), we were not setting direction to output and we were
+assuming gpio_request success all the time.
+Fix it by switching to gpiod functions and adding appropriate checks.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-It wasn't working (on most of devices?) without setting GPIO direction
-and wasn't respecting ACTIVE_LOW flag.
