[PATCH try#4] Blackfin ethernet driver: on chip ethernet MAC controller driver
This patch implements the driver necessary use the Analog Devices Blackfin processor's on-chip ethernet MAC controller. [try#2] - add timeout control - kill dma_config_reg bitfields - some trivial cleanup [try#3] - add endianess check - add DRV_NAME, DRV_VERSION... driver information string - add some comments for silicon anomaly and dma API confusion - some code trivial cleanup [try#4] - add Blackfin latest GPIO pin mux opertion with Michael Hennerich's help and Dan's review - rewrite the DMA descriptor list operation in a more readable way by Joe's review Signed-off-by: Michael Hennerich <[EMAIL PROTECTED]> Signed-off-by: Bryan Wu <[EMAIL PROTECTED]> Cc: Michael Buesch <[EMAIL PROTECTED]> Cc: Mike Frysinger <[EMAIL PROTECTED]> Cc: Jeff Garzik <[EMAIL PROTECTED]> Cc: Christoph Hellwig <[EMAIL PROTECTED]> Cc: Dan Williams <[EMAIL PROTECTED]> Cc: Joe Perches <[EMAIL PROTECTED]> Signed-off-by: Andrew Morton <[EMAIL PROTECTED]> --- MAINTAINERS|7 + drivers/net/Kconfig| 44 ++ drivers/net/Makefile |1 + drivers/net/bfin_mac.c | 1015 drivers/net/bfin_mac.h | 132 +++ 5 files changed, 1199 insertions(+), 0 deletions(-) create mode 100644 drivers/net/bfin_mac.c create mode 100644 drivers/net/bfin_mac.h diff --git a/MAINTAINERS b/MAINTAINERS index 3914269..65d5805 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -754,6 +754,13 @@ L: [EMAIL PROTECTED] (subscribers-only) W: http://blackfin.uclinux.org S: Supported +BLACKFIN EMAC DRIVER +P: Bryan Wu +M: [EMAIL PROTECTED] +L: [EMAIL PROTECTED] (subscribers-only) +W: http://blackfin.uclinux.org +S: Supported + BLACKFIN RTC DRIVER P: Mike Frysinger M: [EMAIL PROTECTED] diff --git a/drivers/net/Kconfig b/drivers/net/Kconfig index d17d64e..7a3edaf 100644 --- a/drivers/net/Kconfig +++ b/drivers/net/Kconfig @@ -848,6 +848,50 @@ config ULTRA32 .
