Daniel DeGrasse	ed64818565	sd: sdio: rework frequency and timing selection logic Reword frequency and timing selection logic for SDIO framework so that the maximum supported timing mode between the card and host will be selected, even if the maximum frequency supported by the host is not equal to the maximum frequency for that mode. Also, resolve an issue where a host and card combo only supporting HS mode or worse would still use legacy timing mode, because the CCCR flags were not being checked when checking if HS bus speed could be used.

Daniel DeGrasse	1c0b114bf8	sd: add timeout when taking SD card lock for data operations Previously, if an SD I/O operation was attempted while another thread held the mutex for the SD card, the I/O operation would simply fail. Add a timeout to k_mutex_lock calls within the SD subsystem, so that multithreaded access to the SD card instead blocks until the SD card is available for I/O Fixes #66211 Signed-off-by: Daniel DeGrasse <daniel.degrasse@nxp.com>	2 years ago
Daniel DeGrasse	726128f810	sd: add SDIO subsystem add SDIO subsystem code. SDIO subsystem currently supports card initialization, SDIO read/write, SDIO extended read/write, and SDIO card interrupts. Signed-off-by: Daniel DeGrasse <daniel.degrasse@nxp.com>	2 years ago
Daniel DeGrasse	b7cd970493	sd: add stub for SDIO support Add stub code for SDIO support, capable of verifying card responds to CMD5. This commit also changes the architecture of the SDIO probe step to make adding new protocol support more streamlined, and enable compiling out support for undesired protocols.
