Changelog: * add support for > 1k zero sum buffer sizes * added dma/aau platform devices to iq80321 and iq80332 setup * fixed the calculation in iop_desc_is_aligned * support xor buffer sizes larger than 16MB * fix places where software descriptors are assumed to be contiguous, only hardware descriptors are contiguous for up to a PAGE_SIZE buffer size * convert to async_tx * add interrupt support * add platform devices for 80219 boards * do not call platform register macros in driver code * remove switch() statements for compatible register offsets/layouts * change over to bitmap based capabilities Cc: Russell King Signed-off-by: Dan Williams --- arch/arm/mach-iop32x/glantank.c | 2 arch/arm/mach-iop32x/iq31244.c | 5 arch/arm/mach-iop32x/iq80321.c | 3 arch/arm/mach-iop32x/n2100.c | 2 arch/arm/mach-iop33x/iq80331.c | 3 arch/arm/mach-iop33x/iq80332.c | 3 arch/arm/plat-iop/Makefile | 2 arch/arm/plat-iop/adma.c | 216 ++++++++ include/asm-arm/arch-iop32x/adma.h | 5 include/asm-arm/arch-iop33x/adma.h | 5 include/asm-arm/hardware/iop3xx-adma.h | 893 ++++++++++++++++++++++++++++++++ include/asm-arm/hardware/iop3xx.h | 68 -- 12 files changed, 1147 insertions(+), 60 deletions(-) diff --git a/arch/arm/mach-iop32x/glantank.c b/arch/arm/mach-iop32x/glantank.c index 45f4f13..2e0099b 100644 --- a/arch/arm/mach-iop32x/glantank.c +++ b/arch/arm/mach-iop32x/glantank.c @@ -180,6 +180,8 @@ static void __init glantank_init_machine(void) platform_device_register(&iop3xx_i2c1_device);
