Hello, These patches are part of the GSoC unselected 'QEMU visualizer' project.
This series introduce a LED device that can be easily connected to a GPIO output. Since v4: - Fixed typos (Luc) - Removed TYPE_TOSA_MISC_GPIO qdev conversion patch (Peter) Since v3: - Rebased (TYPE_TOSA_MISC_GPIO) - Rebased (Meson) - Addressed Richard's review comments - Improved doc/comments Since v2: - Rebased on PCA9552 - Model intensity to be ready for PWM use (Dave) - Remove QMP events until we get a UI visualizer (Peter) - Remove microbit patch (Peter) Since v1: addressed Eric Blake review comments - Added QMP rate limit Next steps planned: - PoC visualizer... - look at using a dbus backend (elmarco) - look at LED array/matrix such 7segments. Regards, Phil.
