Driver - Exynos 7885

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.

There is a growing movement to mainline Exynos 7885 drivers into the (not just Android). The Samsung Exynos7885 Mainline Project on GitHub aims to write open-source drivers for: exynos 7885 driver

Android uses libGLES_mali.so for OpenGL ES and libOpenCL.so for Compute. The blob communicates with the kernel via the mali ioctl interface. Performance is adequate for UI rendering (1080p@60fps) but not for heavy gaming (OpenGL ES 3.2 is supported, but shader performance is limited). The Exynos 7885 uses Samsung’s pinctrl driver for

In this deep-dive article, we will unpack everything you need to know: from the technical architecture of the driver to step-by-step installation guides, common bugs, and the latest updates affecting gaming, battery life, and custom ROMs. I2C buses use the i2c-s3c2410 driver

Let’s break down what the Exynos 7885 driver actually controls, why Samsung stopped updating them, and how the custom development community is keeping this chip alive.
