gpio: Add a driver for SX1509B Adds a driver for SX1509B I2C GPIO chip. This driver only supports the basic GPIO features and does not currently implement the LED driver and keypad matrix features. Signed-off-by: Aapo Vienamo <aapo.vienamo@iki.fi>

menuconfig GPIO_SX1509B
bool "SX1509B I2C GPIO chip"
kconfig: gpio: Remove lots of redundant GPIO dependencies Most of these are from source'ing a file within an 'if GPIO', and then adding another 'depends on GPIO' within it. 'if FOO' is just shorthand for adding 'depends on FOO' to each item within the 'if'. There are no "conditional includes" in Kconfig, so 'if FOO' has no special meaning around a 'source'. Conditional includes wouldn't be possible, because an 'if' condition could include (directly or indirectly) forward references to symbols not defined yet. Tip: When adding a symbol, check its dependencies in the menuconfig ('ninja menuconfig', then / to jump to the symbol). The menuconfig also shows how the file with the symbol got included, so if you see duplicated dependencies, it's easy to hunt down where they come from.

config GPIO_SX1509B_INIT_PRIORITY
Kconfig: Use a short, consistent style for prompts Consistently use config FOO bool/int/hex/string "Prompt text" instead of config FOO bool/int/hex/string prompt "Prompt text" (...and a bunch of other variations that e.g. swapped the order of the type and the 'prompt', or put other properties between them). The shorthand is fully equivalent to using 'prompt'. It saves lines and avoids tricking people into thinking there is some semantic difference. Most of the grunt work was done by a modified version of https://unix.stackexchange.com/questions/26284/ how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some of the rarer variations had to be converted manually.

drivers: gpio: sx1509b: Kconfig options depend on GPIO_SX1509B When CONFIG_GPIO_SX1509B was not set, the related Kconfig options were still showing up in .config. Let's make them depend on GPIO_SX1509B so they can go away when not being used. Signed-off-by: Michael Scott <mike@foundries.io>
