m68k: coldfire: fix breakage of missed IO access update

2026-07-20T00:20:53+00:00

Fix the last remaining breakage caused by missing a SoC IO access update. Commit e1f3a00670d1 ("m68k: coldfire: use ColdFire specifc IO access in SoC code") missed this read16() call which should be mcf_read16().

m68k: coldfire: fix breakage of missed IO access updates

2026-07-08T12:51:54+00:00

Commit e1f3a00670d1 ("m68k: coldfire: use ColdFire specifc IO access in SoC code") incorrectly updated a couple of local IO access uses. They use "read8" when they should be using the new "mcf_read8". Fix them. This causes compile time breakage for two specific SoC types, the ColdFire 5235 and 5282. They got missed in original testing due to not having any defconfigs for these specific parts.

m68k: stmark2: use ioport.h macros for resources

2026-06-11T08:01:48+00:00

Change resource declaration using DEFINE_RES_*() macros. DEFINE_DMA_RES() is for a single dma channel, not a range, so used twice. Also, some drivers assume IRQ resources are from index 1, so just to stay uniform, moved IRQ resource at index 1.

m68k: coldfire: use ColdFire specifc IO access in SoC code

Convert all ColdFire specific SoC/board setup code to only use the newly created internal register access methods. This is replacing the mixed and inconsistent use of readx/writex and __raw_readx/__raw_writex for internal SoC registers. Reviewed-by: Arnd Bergmann Signed-off-by: Greg Ungerer

m68k: coldfire: rename timer register access defines

2026-06-08T03:15:18+00:00

With the basic ColdFire IO register functions now consistently named with a "mcf_read"/"mcf_write" prefix it makes sense to name the timers internal access defines the same way. Convert the local __raw_readtrr and __raw_writetrr defines to use the consistent prefixes too. Thus the change is: __raw_readtrr --> mcf_readtrr __raw_writetrr --> mcf_writetrr Reviewed-by: Arnd Bergmann Signed-off-by: Greg Ungerer
