I've never heard of anyone having used this driver for debugging at least
in over past decade or so. Since we have tools like evtest, this driver
seems to be rather superficial.
Also, it apparently causes confusion among people who accidentaly enable

Currently the pending_async_copies count is decremented just

In accordance with LicheePi 4A BSP the clock that comes to emmc/sdhci
is 198Mhz which is got through frequency division of source clock
VIDEO PLL by 4 [1].
But now the AP_SUBSYS driver sets the CLK EMMC SDIO to the same
