2025-04-11	serial: sh-sci: Introduced sci_of_data	Thierry Bultel	1	-1/+9
	The aim here is to provide an easier support to more different SCI controllers, like the RZ/T2H one. The existing .data field of_sci_match is changed to a structure containing all what that can be statically initialized, and avoid a call to 'sci_probe_regmap', in both 'sci_init_single', and 'early_console_setup'. 'sci_probe_regmap' is now assumed to be called in the only case where the device description is from a board file instead of a dts. In this way, there is no need to patch 'sci_probe_regmap' for adding new SCI type, and also, the specific sci_port_params for a new SCI type can be provided by an external file.

2025-04-11	serial: sh-sci: Introduced function pointers	Thierry Bultel	1	-0/+159
	The aim here is to prepare support for new sci controllers like the T2H/RSCI whose registers are too much different for being handled in common code. This named serial controller also has 32 bits register, so some return types had to be changed. The needed generic functions are no longer static, with prototypes defined in sh-sci-common.h so that they can be used from specific implementation in a separate file, to keep this driver as little changed as possible. For doing so, a set of 'ops' is added to struct sci_port.
