Just like for the memset, it's used on those SoCs to support framebuffer related operations that cannot be performed either by the display engine or the (non-existent) GPU. Let me know what you think, Maxime Maxime Ripard (2): dmaengine: hdmac: factorise memset descriptor allocation dmaengine: hdmac: Add scatter-gathered memset support drivers/dma/at_hdmac.c | 169 ++++++++++++++++++++++++++++++++++---------- drivers/dma/at_hdmac_regs.h | 2 +- 2 files changed, 134 insertions(+), 37 deletions(-) -- 2.5.3
