1 This is a place for planning the ongoing long-term work in the GPIO
8 to move away from the global GPIO numberspace and toward a descriptor-based
17 unmanageable: machine board files tend to become full of macros trying to
18 establish the numberspace at compile-time, making it hard to add any numbers
26 The runtime-assigned GPIO numberspace (what you get if you assign the GPIO
27 base as -1 in struct gpio_chip) has also became unpredictable due to factors
28 such as probe ordering and the introduction of -EPROBE_DEFER making probe
37 - Convert all GPIO device drivers to only #include <linux/gpio/driver.h>

58 the device tree back-end. It is legacy and should not be used in new code.
62 - Change all consumer drivers that #include <linux/of_gpio.h> to
63   #include <linux/gpio/consumer.h> and stop doing custom parsing of the
67 - Pull semantics for legacy device tree (OF) GPIO lookups into
68   gpiolib-of.c: in some cases subsystems are doing custom flags and

120 - Look over and identify any remaining easily converted drivers and
121   dry-code conversions to MMIO GPIO for maintainers to test
123 - Expand the MMIO GPIO or write a new library for regmap-based I/O
127 - Expand the MMIO GPIO or write a new library for port-mapped I/O
128   helpers (x86 inb()/outb()) and convert port-mapped I/O drivers to use

136 MMIO case the regmap MMIO with gpio-regmap.c is preferable over gpio-mmio.c.

150 There are already ways to use pin control as back-end for GPIO and
