[PATCH v3 0/2] Add K230 SoC GPIO controller support

Hi,

Thanks to Daniel Henrique Barboza for reviewing v2. This v3 addresses
all the comments you raised on patch 1/2; patch 2/2 (the qtest) is
unchanged.

The Kendryte K230 SoC contains two APB GPIO controllers derived from
the Synopsys DesignWare APB GPIO (the Linux gpio-k230 driver is itself
based on gpio-dwapb.c, and shares the same register layout), with a
Canaan-specific compatible ("canaan,k230-apb-gpio") and hardlock
integration. This series implements the device model, wires it into
the K230 SoC, and adds qtest coverage.


Changes in v3 (patch 1/2 only):

* Removed the unused `intstatus` field from the device state, the
  vmstate description and the reset hook.

* Moved `qemu/osdep.h` out of k230_gpio.h and into k230_gpio.c as the
  first include.

* Flattened the nested `if` blocks in the SWPORTA_DDR and SWPORTA_CTL
  write paths with an early `continue`, reducing the indentation by two
  levels. `curr_level` and `pol` are now declared at the top of
  k230_gpio_write() to avoid mid-block declarations after the
  `continue`.
