Hi,

Hi,

Add SDIO ids for use with the muRata 1YN (Cypress CYW43439).
The odd thing about this is that the previous 1YN populated
on M.2 card for evaluation purposes had BRCM SDIO vendor ID,
while the chip populated on real hardware has a Cypress one.
The device ID also differs between the two devices. But they
are both 43439 otherwise, so add the IDs for both.

```
/sys/.../mmc_host/mmc2/mmc2:0001 # cat vendor device
0x04b4
0xbd3d
```

Thanks, patch looks good to me:

Thanks. I now assembled the old device and got both IDs, so I will add them to the commit message and send V2. I also noticed that the old device is some ES1.4 chip, while the new one is production silicon:

On-device 1YN (43439), the new one, chip label reads "1YN":
```
/sys/.../mmc_host/mmc2/mmc2:0001 # cat vendor device
0x04b4
0xbd3d
```

EA M.2 evaluation board 1YN (43439), the old one, chip label reads "1YN ES1.4":
```
/sys/.../mmc_host/mmc0/mmc0:0001/# cat vendor device
0x02d0
0xa9a6
```
