[PATCH 0/2] arm64: dts: qcom: sc7180: enable GPI DMA
From: Erikas Bitovtas
Date: Thu Nov 12 2026 - 07:26:35 EST
Enable GPI DMA controller for SC7180 SoC. This can be used to
make access to I2C, SPI and UART peripherals faster.
Tested on Samsung Galaxy A72 on an I2C peripheral, in particular the
Samsung S3NRN4V NFC module located in i2c0 0x27. The peripheral driver
is not upstream yet, submission can be found here:
