2011-10-24MIPS: Alchemy: rewrite USB platform setup.Manuel Lauss
Use runtime CPU detection to setup all USB parts. Remove the Au1200 OTG and UDC platform devices since there are no drivers for them anyway. Clean up the USB address mess in the au1000 header.

2011-10-24MIPS: Alchemy: abstract USB block control register accessManuel Lauss
Alchemy chips have one or more registers which control access to the usb blocks as well as PHY configuration. I don't want the OHCI/EHCI glues to know about the different registers and bits; new code hides the gory details of USB configuration from them.

2011-10-24NET: au1000_eth: Pass MACDMA address through platform resource info.Manuel Lauss
This patch removes the last hardcoded base address from the au1000_eth driver. The base address of the MACDMA unit was derived from the platform device id; if someone registered the MACs in inverse order both would not work. So instead pass the base address of the DMA unit to the driver with the other platform resource information. Signed-off-by: Manuel Lauss <manuel.lauss@googlemail.com> Acked-by: David S.

2011-10-20Revert "MIPS: LD/SD o32 macro GAS fix update"Ralf Baechle
This reverts commit 97475f8b42e83be2966aa2d70ab9c98477701c53 (lmo) / 82b89152f00f7ad17844d5614d5011e8d7944ac9 (kernel.org) [MIPS: LD/SD o32 macro GAS fix update]. Turns out this patch is producing many build errors with gcc 4.2. Based on further testing with a test case extracted from the build errors found further build errors and suboptimal generation even in violation of the "R" constraint. To make matters worse, the binutils changes also don't work quite as intended so revert this patch for now.

2011-09-15net: consolidate and fix ethtool_ops->get_settings callingJiri Pirko
This patch does several things: - introduces __ethtool_get_settings which is called from ethtool code and from drivers as well. Put ASSERT_RTNL there. - dev_ethtool_get_settings() is replaced by __ethtool_get_settings() - changes calling in drivers so rtnl locking is respected. In iboe_get_rate was previously ->get_settings() called unlocked. This fixes it. Also prb_calc_retire_blk_tmo() in af_packet.c had the same problem. Also fixed by calling __dev_get_by_index() instead of dev_get_by_index() and holding rtnl_lock for both calls. - introduces rtnl_lock in bnx2fc_vport_create() and fcoe_vport_create() so bnx2fc_if_create() and fcoe_if_create() are called locked as they are from other places. - use __ethtool_get_settings() in bonding code Signed-off-by: Jiri Pirko <jpirko@redhat.com> v2->v3: -removed dev_ethtool_get_settings() -added ASSERT_RTNL into __ethtool_get_settings() -prb_calc_retire_blk_tmo - use __dev_get_by_index() and lock around it and __ethtool_get_settings() call v1->v2: add missing export_symbol Reviewed-by: Ben Hutchings <bhutchings@solarflare.com> [except FCoE bits] Acked-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S.

2011-08-23mips: msp71xx/serial: add workaround for DW UARTJamie Iles
The Synopsys DesignWare UART in pmc-sierra msp71xx has an extra feature where the UART detects a write attempt to the LCR whilst busy and raises an interrupt. The driver needs to clear the interrupt and rewrite the LCR. Move this into platform code and out of the 8250 driver.
