[PATCH v3 0/4] gpio: sifive: Module support

With the call to of_irq_count() removed, the SiFive GPIO driver can be
built as a module. This helps to minimize the size of a multiplatform
kernel, and is required by some downstream distributions (Android GKI).

This series removes the rest of the of_* API usage in the process.

Changes in v3:
 - Use dev_fwnode() instead of member access
 - Mention the SIFIVE_GPIO_MAX check in the commit message
 - Keep the variable for the parent IRQ domain
 - Add a comment explaining why the IRQ data lookup will succeed

Changes in v2:
 - Add 3 new patches removing of_* API usage
 - Add MODULE_AUTHOR and MODULE_DESCRIPTION

Samuel Holland (4):
  gpio: sifive: Directly use the device's fwnode
  gpio: sifive: Look up IRQs only once during probe
  gpio: sifive: Get the parent IRQ's domain from its irq_data
  gpio: sifive: Allow building the driver as a module
