Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.
Patch generated using:
$ ./scripts/codeconverter/converter.py -i \
--pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')
which will split "typdef struct { ... } TypedefName"
declarations.
Followed by:
$ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
$(git grep -l '' -- '*.[ch]')
which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

|
|
* QEMU interface:
|

* + sysbus MMIO regions 0: GPIO registers
|
|
* + Unnamed GPIO inputs 0-31: Set tri-state input level for GPIO pin.
|
|
* Level -1: Externally Disconnected/Floating; Pull-up/down will be regarded
|
|
* Level 0: Input externally driven LOW
|

* Level 1: Input externally driven HIGH
|
|
* + Unnamed GPIO outputs 0-31:

* Level -1: Disconnected/Floating
|
|
* Level 0: Driven LOW
|
|
* Level 1: Driven HIGH
|
|
*
|
|
* Accuracy of the peripheral model:
|
|
* + The nRF51 GPIO output driver supports two modes, standard and high-current
|
|
* mode. These different drive modes are not modeled and handled the same.
|
|
* + Pin SENSEing is not modeled/implemented.
