sdhci_fdt_rockchip: Don't return 0 from probe routine

2026-02-09T16:27:23+00:00

The only write to the softc is a no-op (softcs are initialized to all
zeroes), so remove that and just use BUS_PROBE_DEFAULT.

sdhci: Try to complete the last transaction if dumping

2025-12-17T14:17:06+00:00

If the kernel panics while a thread is in the middle of an SDHCI
transaction, trying to dump to a dump target on the MMC would result in
a hang.  Fix this by completing the transaction first.

machine/stdarg.h -> sys/stdarg.h

2025-06-11T16:39:02+00:00

Switch to using sys/stdarg.h for va_list type and va_* builtins.

Make an attempt to insert the include in a sensible place.  Where
style(9) was followed this is easy, where it was ignored, aim for the
first block of sys/*.h headers and don't get too fussy or try to fix
other style bugs.

sdhci: Refactor the generic FDT driver

2025-02-07T09:06:07+00:00

This patch refactors the 'sdhci_fdt.c' driver by moving all vendor
specific routines into separate files and making the base 'sdhci_fdt'
driver subclassable. The goal is to make adding new FDT-based drivers
easier and more maintainable. No functional change intended.
