* SD8787 has a "powerdown" line, and CW1200 has a "powerup" line.. I know this is a simple logic inversion.If this is a GPIO line, the GPIO subsystem can flag a line for inverted logic. GPIO_ACTIVE_LOW from device tree for example.
Slight ping on Ulf on this thread :). I do understand the inverted logic flag but that doesn't help if there are different logic states between various chipsets.
