2013-10-10i2c: i2c-stu300: replace platform_driver_probe to support deferred probingWolfram Sang
Subsystems like pinctrl and gpio rightfully make use of deferred probing at core level. Now, deferred drivers won't be retried if they don't have a .probe function specified in the driver struct. Fix this driver to have that, so the devices it supports won't get lost in a deferred probe. Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

2013-10-09xhci: Fix spurious wakeups after S5 on HaswellTakashi Iwai
Haswell LynxPoint and LynxPoint-LP with the recent Intel BIOS show mysterious wakeups after shutdown occasionally. After discussing with BIOS engineers, they explained that the new BIOS expects that the wakeup sources are cleared and set to D3 for all wakeup devices when the system is going to sleep or power off, but the current xhci driver doesn't do this properly (partly intentionally). This patch introduces a new quirk, XHCI_SPURIOUS_WAKEUP, for fixing the spurious wakeups at S5 by calling xhci_reset() in the xhci shutdown ops as done in xhci_stop(), and setting the device to PCI D3 at shutdown and remove ops. The PCI D3 call is based on the initial fix patch by Oliver Neukum. [Note: Sarah changed the quirk name from XHCI_HSW_SPURIOUS_WAKEUP to XHCI_SPURIOUS_WAKEUP, since none of the other quirks have system names in them. Sarah also fixed a collision with a quirk submitted around the same time, by changing the xhci->quirks bit from 17 to 18.] This patch should be backported to kernels as old as 3.0, that contain the commit 1c12443ab8eba71a658fae4572147e56d1f84f66 "xhci: Add Lynx Point to list of Intel switchable hosts."

2013-10-09xhci: fix write to USB3_PSSEN and XUSB2PRM pci config registersXenia Ragiadakou
The function pci_write_config_dword() sets the appropriate byteordering internally so the value argument should not be converted to little-endian. This bug was found by sparse. This patch is not suitable for stable. Since cpu_to_lei32 is a no-op on little endian systems, this bug would only affect big endian Intel systems with the EHCI to xHCI port switchover, which are non-existent, AFAIK.

2013-10-09xhci: Don't enable/disable RWE on bus suspend/resume.Sarah Sharp
The RWE bit of the USB 2.0 PORTPMSC register is supposed to enable remote wakeup for devices in the lower power link state L1. It has nothing to do with the device suspend remote wakeup from L2. The RWE bit is designed to be set once (when USB 2.0 LPM is enabled for the port) and cleared only when USB 2.0 LPM is disabled for the port. The xHCI bus suspend method was setting the RWE bit erroneously, and the bus resume method was clearing it. The xHCI 1.0 specification with errata up to Aug 12, 2012 says in section 4.23.5.1.1.1 "Hardware Controlled LPM": "While Hardware USB2 LPM is enabled, software shall not modify the HIRDBESL or RWE fields of the USB2 PORTPMSC register..." If we have previously enabled USB 2.0 LPM for a device, that means when the USB 2.0 bus is resumed, we violate the xHCI specification by clearing RWE. It also means that after a bus resume, the host would think remote wakeup is disabled from L1 for ports with USB 2.0 Link PM enabled, which is not what we want. This patch should be backported to kernels as old as 3.2, that contain the commit 65580b4321eb36f16ae8b5987bfa1bb948fc5112 "xHCI: set USB2 hardware LPM". That was the first kernel that supported USB 2.0 Link PM. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Cc: stable@vger.kernel.org

abort pending TX In patch 0d1862e can: flexcan: fix flexcan_chip_start() on imx6 the loop in flexcan_chip_start() that iterates over all mailboxes after the soft reset of the CAN core was removed. This loop put all mailboxes (even the ones marked as reserved 1...7) into EMPTY/INACTIVE mode. On mailboxes 8...63, this aborts any pending TX messages. After a cold boot there is random garbage in the mailboxes, which leads to spontaneous transmit of CAN frames during first activation. Further if the interface was disabled with a pending message (usually due to an error condition on the CAN bus), this message is retransmitted after enabling the interface again. This patch fixes the regression by: 1) Limiting the maximum number of used mailboxes to 8, 0...7 are used by the RX FIFO, 8 is used by TX. 2) Marking the TX mailbox as EMPTY/INACTIVE, so that any pending TX of that mailbox is aborted.

2013-10-09perf trace: Show path associated with fd in live sessionsArnaldo Carvalho de Melo
For live sessions we can just access /proc to map an fd to its path, on a best effort way, i.e. sometimes the fd will have gone away when we try to do the mapping, as it is done in a lazy way, only when a reference to such fd is made then the path will be looked up in /proc. This is disabled when processing perf.data files, where we will have to have a way to get getname events, be it via an on-the-fly 'perf probe' event or after a vfs_getname tracepoint is added to the kernel. A first step will be to synthesize such event for the use cases where the threads in the monitored workload exist already.

2013-10-09perf annotate: Reuse path from the result of addr2lineNamhyung Kim
In the symbol__get_source_line(), path and src_line->path will have same value, but they were allocated separately, and leaks one. Just share path to src_line->path.

2013-10-09Merge branch 'for-davem' of ↵David S. Miller
git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless John W. Linville says: =================== Please pull this batch of fixes intended for 3.12... Most of the bits are for iwlwifi -- Johannes says: "I have a fix for WoWLAN/D3, a PCIe device fix, we're removing a warning, there's a fix for RF-kill while scanning (which goes together with a mac80211 fix) and last but not least we have many new PCI IDs." Also for iwlwifi is a patch from Johannes to correct some merge damage that crept into the tree before the last merge window. On top of that, Felix Fietkau sends an ath9k patch to avoid a Tx scheduling hang when changing channels to do a scan. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2013-10-09gianfar: Enable eTSEC-20 erratum w/a for P2020 Rev1Claudiu Manoil
Enable workaround for P2020/P2010 erratum eTSEC 20, "Excess delays when transmitting TOE=1 large frames". The impact is that frames lager than 2500-bytes for which TOE (i.e. TCP/IP hw accelerations like Tx csum) is enabled may see excess delay before start of transmission. This erratum was fixed in Rev 2.0. Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-10-09gianfar: Use mpc85xx support for errata detectionClaudiu Manoil
Use the macros and defines from mpc85xx.h to simplify and prevent errors in identifying a mpc85xx based SoC for errata detection. This should help enabling (and identifying) workarounds for various mpc85xx based chips and revisions. For instance, express MPC8548 Rev.2 as: (SVR_SOC_VER(svr) == SVR_8548) && (SVR_REV(svr) == 0x20) instead of: (pvr == 0x80210020 && mod == 0x8030 && rev == 0x0020) Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: David S.

2013-10-09gianfar: Enable eTSEC-A002 erratum w/a for all partsClaudiu Manoil
A002 is still in "no plans to fix" state, and applies to all the current P1/P2 parts as well, so it's resonable to enable its workaround by default, for all the soc's with etsec. The impact of not enabling this workaround for affected parts is that under certain conditons (runt frames or even frames with RX error detected at PHY level) during controller reset, the controller might fail to indicate Rx reset (GRS) completion.
