Currently the device MMIO APIs is only able to map single DT-defined
regions and also the _NAMED variant is assuming that each DT-defined
device has only one single region to map.
This is a limitation and a problem when in the DT are defined devices
with multiple regions that need to be mapped.
This patch is trying to overcome this limitation by introducing the
DEVICE_MMIO_NAMED_ROM_INIT_BY_NAME macro that leveraged the 'reg-names'
DT property to map multiple regions defined by a single device.
So for example in the DT we can have a device like:
driver@c4000000 {
reg = <0xc4000000 0x1000>, <0xc4001000 0x1000>;
reg-names = "region0", "region1";
};
and then we can use DEVICE_MMIO_NAMED_ROM_INIT_BY_NAME doing:
struct driver_config config = {
DEVICE_MMIO_NAMED_ROM_INIT_BY_NAME(region0, DT_DRV_INST(0)),
DEVICE_MMIO_NAMED_ROM_INIT_BY_NAME(region1, DT_DRV_INST(0)),
};
