H A D | qcom_adm.c | 5c9f8c2d Sat Nov 14 08:02:33 CST 2020 Jonathan McDowell <noodles@earth.li> dmaengine: qcom: Add ADM driver
Add the DMA engine driver for the QCOM Application Data Mover (ADM) DMA controller found in the MSM8x60 and IPQ/APQ8064 platforms.
The ADM supports both memory to memory transactions and memory to/from peripheral device transactions. The controller also provides flow control capabilities for transactions to/from peripheral devices.
The initial release of this driver supports slave transfers to/from peripherals and also incorporates CRCI (client rate control interface) flow control.
The hardware only supports a 32 bit physical address, so specifying !PHYS_ADDR_T_64BIT gives maximum COMPILE_TEST coverage without having to spend effort on kludging things in the code that will never actually be needed on real hardware.
