* pin_repository: provide readable pin names in error cases
* io_pins: remove getBrain_pin_eExt
We have getBrain_pin_eExt in io_pins.cpp and hwPortname in
pin_repository.cpp.
First uses auto-generated enums, second one uses runtime data to
provide name of hw pin.
Removing first saves us about 2K of flash couse big auto-generated
switch with pin names no more used by anyone and gets optimized out.
* gpios: mc33972: CS pin is now requested at smart_gpios.pcc
* getSpiDevice: support SPI4
* smart_gpios.cpp: startSmartCsPins set CSs to inactive state
OutputPin:initPin initializes pin with false value. This is active
state for SPI Chip Selects. Set to 1 to deselect all chips.
* smart_gpio.cpp: check _add return values
And occupy gpiochip's pin range if disabled of failed. So base will
align with enum.
* TLE8888: cleanup, move high level code to smart_gpio.cpp
* smart_gpio.cpp: fix compilation when BOARD_EXT_GPIOCHIPS == 0
* board-subaru: fix compilation after latest smart_gpio updates
* tle8888: now we have all 28 pins supported
* gpio-chips core function renames
* efi_gpio, pin_repository: add support for external gpios
* gpio-chips update
* gpio-chips: add api to name each pin of gpiochip
* tle6240: provide individual names for each pin
