My question was more related to the idle path. In a scenario where
you start using the SDIO functionality and after some time you leave
the SDIO card idle, does the FCLK still remain enabled? Or do you see
that sdio_irq_thread exits and disables the FCLK?
What do you mean

Perhaps I'm misunderstanding what you're referring to, but it seems there

Also, keep in mind that the buffers for transfers must begin and end on
a word boundary. The OMAP's DMA controller can only transfer whole
words to the MMC FIFO.

The 6882a8c sdhci: Add better ADMA error reporting commit added
sdhci_show_adma_error() which is built when DEBUG is defined.
Since we already have CONFIG_MMC_DEBUG used elsewhere in this driver,
may as well make consistent use of that config knob instead.

If I look in the mainline kernel today there is only one SDIO card driver
sdio_uart.c. And at least I don't see a way I can test any of these

There are many other SDIO drivers in the kernel today:

Although the SD Host Controller Simplified Specification Version 2.00
does not clearly document support for 8-bit bus width, it does show
an Extended Data Transfer Width field in bit-5 of the Host Control
