Hello All, I have a new iMX6SL custom board with WiLink8 chipset. The chipset has some features of SDIO 3.0 support and the I/O is 1.8v. I used the mainline kernel 3.13 and 3.19, both of them detected it. But, the problem is the voltage signaling is 3.3v and it should be 1.8v. clock: 50000000 Hz actual clock: 49500000 Hz vdd: 7 (1.65 - 1.95 V) bus mode: 2 (push-pull) chip select: 0 (don't care) power mode: 2 (on) bus width: 2 (4 bits) timing spec: 2 (sd high-speed) --->>> signal voltage: 0 (3.30 V) <---> it should be 1.8v I would like to know if there's any available patches out there that I could use in order support SDR25?.
