struct platform_device { const char *name; int id; bool id_auto; struct device dev; u32 num_resources; struct resource *resource; const struct platform_device_id *id_entry; /* MFD cell pointer */ struct mfd_cell *mfd_cell; /* arch specific additions */ struct pdev_archdata archdata; };

- pdev_archdata? platform_device.archdata?
ドキュメント
メモ
- platform_driver.probeの引数として渡される
- platform_deviceは，name, id, resource (ともちろん dev へのポインタ) だけの構造体で，これがbus? に相当する。
- platform_device.resource構造体の中にIRQ,メモリマップ、レジスタなどのアドレス情報などを入れる．
例
使われ所
- dwc3_probe(platform_device *pdev) //platform_driver.probe
