Can we do u64 here please.. I dont know where we would end up.. but would hate if we start running out of space ..
No objection.
Also, is the sdw_master_prop right place for a 'quirk' property. I think we can use sdw_master_device or sdw_bus as this seems like a bus quirk..?
It's already part of sdw_bus
struct sdw_bus { struct device *dev; struct sdw_master_device *md; unsigned int link_id; int id; struct list_head slaves; DECLARE_BITMAP(assigned, SDW_MAX_DEVICES); struct mutex bus_lock; struct mutex msg_lock; int (*compute_params)(struct sdw_bus *bus); const struct sdw_master_ops *ops; const struct sdw_master_port_ops *port_ops; struct sdw_bus_params params; struct sdw_master_prop prop;
The quirks could be set by a firmware property, and it seems logical to add them at the same place where we already have properties defined in firmware, no? That way all the standard, vendor-specific and quirks are read or added in the same place.
the sdw_master_device isn't a good place for quirks IMHO, it's a very shallow software-only layer without any existing ties to the hardware definition.
