24 know for example that GPIO #23 controls the write protect line used to
25 protect boot loader segments in flash memory. System upgrade procedures
27 then changing its output state, then updating the code before re-enabling
28 the write protection. In normal use, GPIO #23 would never be touched,

47    -	Control interfaces used to get userspace control over GPIOs;
49    -	GPIOs themselves; and
51    -	GPIO controllers ("gpio_chip" instances).
55 The control interfaces are write-only:
73 and have the following read/write attributes:
94 		If the pin can be configured as interrupt-generating interrupt
103 		re-open it to read the value.
107 		"both". Write these strings to select the signal edge(s)
114 		reads as either 0 (false) or 1 (true). Write
