VT6420 seems to have the same hotplug capability as VT6421. However, enabling hotplug needs to expose SCR registers which can cause problems. It works for me but might break elsewhere. So add a module parameter vt6420_hotplug to enable this feature. Signed-off-by:

This commit makes use of the AHCI_HFLAG_YES_ALPM flag to prevent the driver from writing to the read-only Host Capability register. It also sets the AHCI_HFLAG_NO_WRITE_TO_RO flag to prevent the AHCI library from writing to read-only registers. Signed-off-by:

While most hardware will simply ignore a write to a read-only register, some hardware will signal an abort if this occurs. This commit introduces the flag AHCI_HFLAG_NO_WRITE_TO_RO to prevent the AHCI library from attempting to write to the HOST_CAP, HOST_CAP2, and HOST_PORTS_IMPL registers which may be read-only.

Some hardware is capable of supporting Aggresive Link Power Management even though it is not indicated by the Host Capability register. This commit adds the AHCI_HFLAG_YES_ALPM flag to the AHCI library to allow indication of this quirk when the Host Capability register is Read Only and therefore cannot be changed. Signed-off-by:

This adds a driver for the Faraday Technology FTIDE010 PATA IP block. When used with the Storlink/Storm/Cortina Systems Gemini SoC, the PATA interface is accompanied by a PATA<->SATA bridge, so while the device appear as a PATA controller, it attaches physically to SATA disks, and also has a designated memory area with registers to set up the bridge. The Gemini SATA bridge is separated into its own driver file to make things modular and make it possible to reuse the PATA driver as stand-alone on other systems than the Gemini. dmesg excerpt from the D-Link DIR-685 storage router: gemini-sata-bridge 46000000.sata: SATA ID 00000e00, PHY ID: 01000100 gemini-sata-bridge 46000000.sata: set up the Gemini IDE/SATA nexus ftide010 63000000.ata: set up Gemini PATA0 ftide010 63000000.ata: device ID 00000500, irq 26, io base 0x63000000 ftide010 63000000.ata: SATA0 (master) start gemini-sata-bridge 46000000.sata: SATA0 PHY ready scsi host0: pata-ftide010 ata1: PATA max UDMA/133 irq 26 ata1.00: ATA-8: INTEL SSDSA2CW120G3, 4PC10302, max UDMA/133 ata1.00: 234441648 sectors, multi 1: LBA48 NCQ (depth 0/32) ata1.00: configured for UDMA/133 scsi 0:0:0:0: Direct-Access ATA INTEL SSDSA2CW12 0302 PQ: 0 ANSI: 5 ata1.00: Enabling discard_zeroes_data sd 0:0:0:0: [sda] 234441648 512-byte logical blocks: (120 GB/112 GiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA ata1.00: Enabling discard_zeroes_data ata1.00: Enabling discard_zeroes_data sd 0:0:0:0: [sda] Attached SCSI disk After this I can flawlessly mount and read/write copy etc files from /dev/sda[n].

This adds device tree bindings for the Faraday Technology FTIDE010 found in the Storlink/Storm/Cortina Systems Gemini SoC. I am not 100% sure that this part is from Faraday Technology but a lot points in that direction: - A later IDE interface called FTIDE020 exist and share some properties. - The SATA bridge has the same Built In Self Test (BIST) that the Faraday FTSATA100 seems to have, and it has version number 0100 in the device ID register, so this is very likely a FTSATA100 bundled with the FTIDE010.

When running LDom binding/unbinding test, kernel may panic in ldmvsw_open(). It is more likely that because we're removing the ldc connection before unregistering the netdev in vsw_port_remove(), we set up a window of time where one process could be removing the device while another trying to UP the device. This also sometimes causes vio handshake error due to opening a device without closing it completely. We should unregister the netdev before we disable the "hardware".

Every address gets added with TENTATIVE flag even for the addresses with IFA_F_NODAD flag and dad-work is scheduled for them. During this DAD process we realize it's an address with NODAD and complete the process without sending any probe. However the TENTATIVE flags stays on the address for sometime enough to cause misinterpretation when we receive a NS. While processing NS, if the address has TENTATIVE flag, we mark it DADFAILED and endup with an address that was originally configured as NODAD with DADFAILED. We can't avoid scheduling dad_work for addresses with NODAD but we can avoid adding TENTATIVE flag to avoid this racy situation. Signed-off-by:
