* hw/gpio: Add GPIO model for Nuvoton NPCM7xxHavard Skinnemoen2020-10-271-0/+7
| | | | | | | | | | | | | | | | The NPCM7xx chips have multiple GPIO controllers that are mostly identical except for some minor differences like the reset values of some registers. Each controller controls up to 32 pins. Each individual pin is modeled as a pair of unnamed GPIOs -- one for emitting the actual pin state, and one for driving the pin externally. Like the nRF51 GPIO controller, a gpio level may be negative, which means the pin is not driven, or floating.

* hw/riscv: Move sifive_gpio model to hw/gpioBin Meng2020-09-101-0/+6
| | | | | | | | | | | | | | This is an effort to clean up the hw/riscv directory. Ideally it should only contain the RISC-V SoC / machine codes plus generic codes. Let's move sifive_gpio model to hw/gpio directory. Note this also removes the trace-events in the hw/riscv directory, since gpio is the only supported trace target in that directory.

* trace-events: Shorten file names in commentsMarkus Armbruster2019-03-221-1/+1
| | | | | | | | | | | | | | | 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.

* trace: enforce that every trace-events file has a final newlineDaniel P. Berrangé2019-01-241-1/+1
| | | | | | | | | | | | | | When generating the trace-events-all file, the build system simply concatenates all the individual trace-events files. If any one of those files does not have a final newline, the printf format string will have the contents of the first line of the next file appended to it, which is usually a '#' comment.

* hw/gpio/nrf51_gpio: Add nRF51 GPIO peripheralSteffen Görtz2019-01-071-0/+7
This adds a model of the nRF51 GPIO peripheral. Reference Manual: http://infocenter.nordicsemi.com/pdf/nRF51_RM_v3.0.pdf The nRF51 series microcontrollers support up to 32 GPIO pins in various configurations. The pins can be used as input pins with pull-ups or pull-down. Furthermore, three different output driver modes per level are available (disconnected, standard, high-current). The GPIO-Peripheral has a mechanism for detecting level changes which is not featured in this model.
