Returns N+1 bytes, where N is the number of Moxtet connected		modules. The first byte is from the CPU board itself. 		Example:: 			101214 		==  =======================================		10  CPU board with SD card		12  2 = PCIe module, 1 = IRQ not active		14  4 = Peridot module, 1 = IRQ not active		==  ======================================= What:		/sys/kernel/debug/moxtet/outputDate:		March 2019KernelVersion:	5.3Contact:	Marek Behún <kabel@kernel.org>Description:	(RW) Read last written value to the shift registers, in		hexadecimal, or write values to the shift registers, also		in hexadecimal. 		Example:: 		    0102 		==  ================================================		01  01 was last written, or is to be written, to the		    first module's shift register		02  the same for second module		==  ================================================
