2017-06-12ata: declare ata_port_info structures as constBhumika Goyal
ata_port_info structures are either copied to other objects or their references are stored in objects of type const. So, ata_port_info structures having similar usage pattern can be made const. Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Tejun Heo <tj@kernel.org>
2017-06-12ata: Add driver for Faraday Technology FTIDE010Linus Walleij
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].

2017-05-24Revert "ata: sata_mv: Convert to devm_ioremap_resource()"Andrew Lunn
This reverts commit 368e5fbdfc60732643f34f538823ed4bc8829827. devm_ioremap_resource() enforces that there are no overlapping resources, where as devm_ioremap() does not. The sata phy driver needs a subset of the sata IO address space, so maps some of the sata address space. As a result, sata_mv now fails to probe, reporting it cannot get its resources, and so we don't have any SATA disks.

2017-05-16ata: libahci: properly propagate return value of platform_get_irq()Thomas Petazzoni
When platform_get_irq() fails, it returns an error code, which libahci_platform and replaces it by -EINVAL. This commit fixes that by propagating the error code. It fixes the situation where platform_get_irq() returns -EPROBE_DEFER because the interrupt controller is not available yet, and generally looks like the right thing to do. We pay attention to not show the "no irq" message when we are in an EPROBE_DEFER situation, because the driver probing will be retried later on, once the interrupt controller becomes available to provide the interrupt.

2017-05-16ahci: Acer SA5-271 SSD Not Detected FixSui Chen
(Correction in this resend: fixed function name acer_sa5_271_workaround; fixed the always-true condition in the function; fixed description.) On the Acer Switch Alpha 12 (model number: SA5-271), the internal SSD may not get detected because the port_map and CAP.nr_ports combination causes the driver to skip the port that is actually connected to the SSD. More specifically, either all SATA ports are identified as DUMMY, or all ports get ``link down'' and never get up again. This problem occurs occasionally. When this problem occurs, CAP may hold a value of 0xC734FF00 or 0xC734FF01 and port_map may hold a value of 0x00 or 0x01. When this problem does not occur, CAP holds a value of 0xC734FF02 and port_map may hold a value of 0x07. Overriding the CAP value to 0xC734FF02 and port_map to 0x7 significantly reduces the occurrence of this problem.

Without this patch, failed probe would not free resources like irq. ata port tdev object currently hold a reference to the ata port object. Therefore the ata port object release function will not get called until the ata_tport_release is called. But that would never happen, releasing the last reference of ata port dev is done by scsi_host_release, which is called by ata_host_release when the ata port object is released. The ata device objects actually do not need to explicitly hold a reference to their real counterpart, given the transport objects are the children of these objects and device_add() is call for each child. We know the parent will not be deleted until we call the child's device_del().

2017-02-27scripts/spelling.txt: add "followings" pattern and fix typo instancesMasahiro Yamada
Fix typos and add the following to the scripts/spelling.txt: followings||following While we are here, add a missing colon in the boilerplate in DT binding documents. The "you SoC" in allwinner,sunxi-pinctrl.txt was fixed as well. I reworded "as the followings:" to "as follows:" for drivers/usb/gadget/udc/renesas_usb3.c.
