* 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.
* io_pins: implement efiSetPadUnused
When pin becomes unused it should be switched to safe mode and
disconnected from any IP block. Assume that gpio input mode with
pull-up is safe enough.
* trigger_input: switch triggers pins to safe mode on stop/reinit
* digital_input_exti: rework
* rename enableExti to efiExtiEnablePin
* add efiExtiDisablePin
* keep track of used exti channels
* trigger_input: use digital_input_exti functions
* 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
* Some more include fixes for linux
* Pass cross-compile path through CROSS_COMPILE
* Lower-upper case conversion fixes for linux
* Rename unmarkPin to brain_pin_markUnused
This is part of external gpiochip integration
* Add gpio_pin prefix to markUsed and markUnused
To distinguish from similar functions using brain_pin
* pin_repository: add helpers
this is part of gpio chips integration
* efi_gpio: simplify getHwPin using brain_pin_is_onchip
