From aad7ad2a01e774f5cd0dde8f0bc6e253ae3f0d35 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 9 Aug 2019 18:33:18 +0200 Subject: [PATCH] dma: iop-adma: allow building without platform headers Now that iop3xx and iop13xx are gone, the iop-adma driver no longer needs to deal with incompatible register layout defined in machine specific header files. Move the iop32x specific definitions into drivers/dma/iop-adma.h and the platform_data into include/linux/platform_data/dma-iop32x.h, and change the machine code to no longer reference those. The DMA0_ID/DMA1_ID/AAU_ID macros are required as part of the platform data interface and still need to be visible, so move those from one header to the other.
