usb: typec: tipd: Separate reset for TPS6598x
Some platforms like SK-AM62, SK-AM62A cannot boot up to prompt if TPS6598x is cold-reset during unconditionally on probe failures by sending "GAID" sequence. The probe can fail initially because USB0 remote-endpoint may not be probed yet, which defines the usb-role-switch property. Fixes: d49f90822015 ("usb: typec: tipd: add init and reset functions to tipd_data") Closes: https://lore.kernel.org/linux-usb/vmngazj6si7xxss7txenezkcukqje2glhvvs7ipdcx3vjiqvlk@ohmmhhhlryws/ Signed-off-by: Jai Luthra <j-luthra@ti.com> Reviewed-by: Roger Quadros <rogerq@kernel.org> Reviewed-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Link: https://lore.kernel.org/r/20240105-next-tps-fix-v1-1-158cabaec168@ti.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
