Hi Michael, Nick, I was wondering if PIKA Warp board still relevant. The reason for my question is that I am interested in dropping legacy gpio APIs, especially OF-specific ones, in favor of newer gpiod APIs, and arch/powerpc/platforms/44x/warp.c is one of few users of it.
The code in question is supposed to turn off green led and flash red led in case of overheating, and is doing so by directly accessing GPIOs owned by led-gpio driver without requesting/allocating them. This is not really supported with gpiod API, and is not a good practice in general. Before I spend much time trying to implement a replacement without access to the hardware, I wonder if this board is in use at all, and if it is how important is the feature of flashing red led on critical temperature shutdown? Thanks. -- Dmitry
