Community-led projects often modify these drivers to support custom operating systems like . Developers use Device Trees
The Exynos 7885 uses Samsung’s pinctrl driver for GPIO banks (gpa0, gpa1, gpb0, etc.). The pinctrl-exynos.c driver handles interrupt mapping and pin muxing. Serial drivers ( exynos-uart.c ) support four UART ports with DMA. I2C buses use the i2c-s3c2410 driver. exynos 7885 driver
Before diving into downloads and troubleshooting, it is critical to understand what a driver does in the context of an Exynos SoC. Community-led projects often modify these drivers to support
