All, just noticed belatedly that the Makefile hunk of patch 9 does no longer apply cleanly in 4.17-rc1, sorry. My series was based on 4.16. I'll resend that one, OK? Cheers, Michael On Wed, Apr 18, 2018 at 4:26 PM, Michael Schmitz <schmitzmic@xxxxxxxxx> wrote:
This patch series adds support for the Individual Computers X-Surf 100 network card for m68k Amiga, a network adapter based on the AX88796 chip set. The driver was originally written for kernel version 3.19 by Michael Karcher (see CC:), and adapted to 4.16 for submission to netdev by me. Questions regarding motivation for some of the changes are probably best directed at Michael Karcher. The driver has been tested by Adrian <glaubitz@xxxxxxxxxxxxxxxxxxx> who will send his Tested-by tag separately. A few changes to the ax88796 driver were required: - to read the MAC address, some setup of the ax99796 chip must be done, - attach to the MII bus only on device open to allow module unloading, - allow to supersede ax_block_input/ax_block_output by card-specific optimized code, - use an optional interrupt status callback to allow easier sharing of the card interrupt, - set IRQF_SHARED if platform IRQ resource is marked shareable, The Asix Electronix PHY used on the X-Surf 100 is buggy, and causes the software reset to hang if the previous command sent to the PHY was also a soft reset. This bug requires addition of a PHY driver for Asix PHYs to provide a fixed .soft_reset function, included in this series. Some additional cleanup: - do not attempt to free IRQ in ax_remove (complements 82533ad9a1c), - clear platform drvdata on probe fail and module remove. Changes since v1: Raised in review by Andrew Lunn: - move MII code around to avoid need for forward declaration - combine patches 2 and 7 to add cleanup in error path Changes since v2: - corrected authorship attribution to Michael Karcher Suggested by Geert Uytterhoeven: - use ei_local->reset_8390() instead of duplicating ax_reset_8390() - use %pR to format struct resource pointers - assign pdev and xs100 pointers in declaration - don't split error messages - change Kconfig logic to only require XSURF100 set on Amiga Suggested by Andrew Lunn: - add COMPILE_TEST to ax88796 Kconfig options - use new Asix PHY driver for X-Surf 100 Suggested by Andrew Lunn/Finn Thain: - declare struct sk_buff in ax88796.h - correct whitespace error in ax88796.h This series' patches, in order: 1/9 net: phy: new Asix Electronics PHY driver 2/9 net: ax88796: Fix MAC address reading 3/9 net: ax88796: Attach MII bus only when open 4/9 net: ax88796: Do not free IRQ in ax_remove() (already freed in ax_close()). 5/9 net: ax88796: Add block_input/output hooks to ax_plat_data 6/9 net: ax88796: add interrupt status callback to platform data 7/9 net: ax88796: set IRQF_SHARED flag when IRQ resource is marked as shareable 8/9 net: ax88796: release platform device drvdata on probe error and module remove 9/9 net: New ax88796 platform driver for Amiga X-Surf 100 Zorro board (m68k) drivers/net/ethernet/8390/Kconfig | 17 ++- drivers/net/ethernet/8390/Makefile | 1 + drivers/net/ethernet/8390/ax88796.c | 228 ++++++++++++-------- drivers/net/ethernet/8390/xsurf100.c | 381 ++++++++++++++++++++++++++++++++++ drivers/net/phy/Kconfig | 6 + drivers/net/phy/Makefile | 1 + drivers/net/phy/asix.c | 65 ++++++ drivers/net/phy/phy_device.c | 3 +- include/linux/phy.h | 1 + include/net/ax88796.h | 14 ++ 10 files changed, 621 insertions(+), 96 deletions(-) Cheers, Michael
