* hw/char/cadence_uart: add clock supportDamien Hedde2020-04-301-0/+3
| | | | | | | | | | | | | | | | | | | Switch the cadence uart to multi-phase reset and add the reference clock input. The input clock frequency is added to the migration structure. The reference clock controls the baudrate generation. If it disabled, any input characters and events are ignored. If this clock remains unconnected, the uart behaves as before (it default to a 50MHz ref clock). Signed-off-by: Damien Hedde <damien.hedde@greensocs.com> Reviewed-by: Edgar E.

* hw/char/exynos4210_uart: Add receive DMA supportGuenter Roeck2020-01-231-0/+2
| | | | | | | | | | | | | | To support receive DMA, we need to inform the DMA controller if receive data is available. Otherwise the DMA controller keeps requesting data, causing receive errors. Implement this using an interrupt line. The instantiating code then needs to connect the interrupt with the matching DMA controller GPIO pin.

* trace-events: Fix attribution of trace points to sourceMarkus Armbruster2019-03-221-1/+1
| | | | | | | | | | | | | | | Some trace points are attributed to the wrong source file. Happens when we neglect to update trace-events for code motion, or add events in the wrong place, or misspell the file name. Clean up with help of cleanup-trace-events.pl. Same funnies as in the previous commit, of course. Manually shorten its change to linux-user/trace-events to */signal.c.

* trace-events: Shorten file names in commentsMarkus Armbruster2019-03-221-12/+12
| | | | | | | | | | | | | | | We spell out sub/dir/ in sub/dir/trace-events' comments pointing to source files. That's because when trace-events got split up, the comments were moved verbatim. Delete the sub/dir/ part from these comments. Gets rid of several misspellings.
