Merge tag 'reset-gpio-for-v6.19' of https://git.pengutronix.de/git/pza/linux into gpio/for-next
Reset/GPIO/swnode changes for v6.19 * Extend software node implementation, allowing its properties to reference existing firmware nodes. * Update the GPIO property interface to use reworked swnode macros. * Rework reset-gpio code to use GPIO lookup via swnode. * Fix spi-cs42l43 driver to work with swnode changes.
