These patches are a respin of Clement's work on the rpi2 sd controller/gpio. They fix the valgrind issue that I was seeing because we got reparenting of the card wrong.
This patchset adds a new qdev patch which makes the qdev_set_parent_bus() function do most of the work of unplugging and replugging if the device was already on a bus. In particular it calls bus_remove_child() which does a lot of things that the previous "just call object_unparent" attempt didn't do. Comments on whether this makes sense to people welcome. I'm still kind of hoping we can squeeze this into 2.9; comments on whether that would be unwise also welcome. thanks -- PMM Clement Deschamps (3): hw/sd: add card-reparenting function bcm2835_gpio: add bcm2835 gpio controller bcm2835: add sdhost and gpio controllers Peter Maydell (1): qdev: Have qdev_set_parent_bus() handle devices already on a bus hw/gpio/Makefile.objs | 1 + include/hw/arm/bcm2835_peripherals.h | 4 + include/hw/gpio/bcm2835_gpio.h | 39 ++++ include/hw/sd/sd.h | 11 ++ hw/arm/bcm2835_peripherals.c | 43 ++++- hw/core/qdev.c | 14 ++ hw/gpio/bcm2835_gpio.c | 353 +++++++++++++++++++++++++++++++++++ hw/sd/core.c | 27 +++ 8 files changed, 490 insertions(+), 2 deletions(-) create mode 100644 include/hw/gpio/bcm2835_gpio.h create mode 100644 hw/gpio/bcm2835_gpio.c -- 2.7.4
