This patch adds an initial DRM driver for the Loongson LS7A1000
bridge chip(LS7A). The LS7A bridge chip contains two display
controllers, support dual display output. The maximum support for
each channel display is to 1920x1080@60Hz.
At present, DC device detection and DRM drive
Implement use GPIO and I2C driver to detect connector
and fetch EDID via DDC.
v4:
- Delete the gpioo_chip subsystem call.
- Delete some redundant prints.
v3:
- Change some driver log to the drm_ version.
v2:
- Optimize the error handling process.
- Delete loongson_i2c_bus_match and loongson_i2c_
Add LS7A DC vsync interrupt enable and close function, and
register irq_handler function interface.
Add vbrank event processing flow.
v4:
- Replace drm_irq_install with devm_request_irq.
- Delete the irq_ hooks in drm_driver.
v3:
- Improve code readability.
- Use the to_pci_dev function to get pc
