ESP32-S3 SDMMC not running 40Mhz on 4.4.3

[narrob]

Using ESP32-S3-N8R2 with SDMMC 4-bit mode. It runs fine on 20 MHz SD Mode when compiling with 4.4.3. Fails when trying to up it to 40 MHz. The same exact board & code runs 40 MHz when compiling with v5.0 or Master branch. On v5.0+ it run 40 MHz with no issue every reset.

External Pull-ups are in place for the SD Card pins.

There was a patch released for V5 to fix the io clock and fixed this exact issue with ESP32-S3.

I've asked months ago if there was a patch for 4.4.3 but no replies. Here is the reference to that patch & question

Looking for a fix so the S3 can always mount correctly on 4.4.3 with SDMMC_FREQ_HIGHSPEED.

Thanks
