-Subject: [PATCH] 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.
