AM623: Software SDIO over GPIO using ti,am62-sdhci driver

Part Number: AM623

Tool/software:

We want to interface silicon lab Si917x WiFi+BLE module with AM623 on our prototype board. Unfortunately, we haven't any mmc pin connected to it. So, I want to use GPIO pins as software SDIO pins over ti,am62-sdhci driver code. (CLK, CMD and DATA pin all are connected with GPIO on AM623 side)

What should be example device tree with some random GPIO for that?

Please check possibility and reply soon.

Part used: AM6232ATCGHAALW

Pin connected with wifi module

  1. MCASP0_AXR2: A19: D1 (Wi-Fi Module)
