16 A GPIO chip handles one or more GPIO lines. To be considered a GPIO chip, the
17 lines must conform to the definition: General Purpose Input/Output. If the
19 GPIO chip. The use case is the indicative: certain lines in a system may be
24 Inside a GPIO driver, individual GPIO lines are identified by their hardware
30 lines are handled by one bit per line in a 32-bit register, it makes sense to
49 2000-2063 to identify GPIO lines in a bank of I2C GPIO expanders.
65 - optional line names array to identify lines
80 Any debugfs dump method should normally ignore lines which haven't been
94 GPIO lines can be configured for several electrical modes of operation by using
116 GPIO lines with debounce support
133 GPIO lines with open drain/source support
157 is driving the SCL and SDA lines of an I2C bus, which is by definition a
197 hard-wired lines that will only support open drain or open source no matter
230 GPIO lines with pull up/down resistor support
239 most you will think about these lines is that they will very likely be
411 If some GPIO lines do not have corresponding IRQs, the bitmask valid_mask
413 lines as invalid for associating with IRQs.
650 If there is a need to exclude certain GPIO lines from the IRQ domain handled by
653 .irq.valid_mask with as many bits set as there are GPIO lines in the chip, each
654 bit representing line 0..n-1. Drivers can exclude GPIO lines by clearing bits
