Merge tag 'reset-for-v6.18' of https://git.pengutronix.de/git/pza/linux into soc/drivers
Reset controller updates for v6.18
* Fix the reset tree git repository link in MAINTAINERS.
* Add support for bcm63xx ephy reset control to reset-bcm6345.
* Add support for the AST2700 reset controller, as an auxiliary
device driver to the corresponding clock controller driver.
* Add support for the remaining TH1520 VO subsystem reset controls to
reset-th1520.
* Drop unnecessary .fast_io setting from MMIO regmap_configs.
* tag 'reset-for-v6.18' of https://git.pengutronix.de/git/pza/linux:
reset: remove unneeded 'fast_io' parameter in regmap_config
reset: th1520: add resets for display pipeline
dt-bindings: reset: thead,th1520-reset: add more VOSYS resets
reset: aspeed: register AST2700 reset auxiliary bus device
reset: bcm6345: add support for bcm63xx ephy control register
dt-bindings: reset: add compatible for bcm63xx ephy control
