2012-08-07canfd: remove redundant CAN FD flagOliver Hartkopp1-12/+13
The first idea of the CAN FD implementation started with a new struct canfd_frame to be used for both CAN FD frames and legacy CAN frames. The now mainlined implementation supports both CAN frame types simultaneously and distinguishes them only by their required sizes: CAN_MTU and CANFD_MTU. Only the struct canfd_frame contains a flags element which is needed for the additional CAN FD information. As CAN FD implicitly means that the 'Extened Data Length' mode is enabled the formerly defined CANFD_EDL bit became redundant and also confusing as an unset bit would be an error and would always need to be tested. This patch removes the obsolete CANFD_EDL bit and clarifies the documentation for the use of struct canfd_frame and the CAN FD relevant flags.

2012-08-07igb: add delay to allow igb loopback test to succeed on 8086:10c9Stefan Assmann1-0/+3
Some 8086:10c9 NICs have a problem completing the ethtool loopback test. The result looks like this: ethtool -t eth1 The test result is FAIL The test extra info: Register test (offline) 0 Eeprom test (offline) 0 Interrupt test (offline) 0 Loopback test (offline) 13 Link test (on/offline) 0 A bisect clearly points to commit a95a07445ee97a2fef65befafbadcc30ca1bd145. However that seems to only trigger the bug. While adding some printk the problem disappeared, so this might be a timing issue. After some trial and error I discovered that adding a small delay just before igb_write_phy_reg() in igb_integrated_phy_loopback() allows the loopback test to succeed. I was unable to figure out the root cause so far but I expect it to be somewhere in the following executing path igb_integrated_phy_loopback ->igb_write_phy_reg_igp ->igb_write_phy_reg_mdic ->igb_acquire_phy_82575 ->igb_acquire_swfw_sync_82575 The problem could only be observed on 8086:10c9 NICs so far and not all of them show the behaviour. I did not restrict the workaround to this type of NIC as it should do no harm to other igb NICs. With the patch below the loopback test succeeded 500 times in a row using a NIC that would otherwise fail.

2012-08-07e1000e: 82571 Tx Data Corruption during Tx hang recoveryTushar Dave1-2/+4
A bus trace shows that while executing e1000e_down, TCTL is cleared except for the PSP bit. This occurs while in the middle of fetching a TSO packet since the Tx packet buffer is full at that point. Before the device is reset, the e1000_watchdog_task starts to run from the middle (it was apparently pre-empted earlier, although that is not in the trace) and sets TCTL.EN. At that point, 82571 transmits the corrupted packet, apparently because TCTL.MULR was cleared in the middle of fetching a packet, which is forbidden. Driver should just clear TCTL.EN in e1000_reset_hw_82571 instead of clearing the entire register, so as not to change any settings in the middle of fetching a packet.

2012-08-07gpio/mxc: specify gpio base for device tree probeShawn Guo1-1/+2
Currently, unlike the non-DT probe where the gpio base is specified with pdev->id, the DT probe uses the base dynamically allocated by gpio core, which uses a completely different numbering scheme. This causes two issues to user space applications which access sysfs entry /sys/class/gpio/gpioN. * It breaks the compatibility with user space applications between non-DT and DT kernels. * It's not intuitive and sometimes hard for users to map the Linux gpio number to the actual hardware pin. Use alias to identify the gpio port/bank, and then the gpio base can be specified with port id to solve above issues. If alias is not defined in device tree, the base number dynamically allocated by gpio core will be used.

2012-08-06fuse: verify all ioctl retry iov elementsZach Brown1-1/+1
Commit 7572777eef78ebdee1ecb7c258c0ef94d35bad16 attempted to verify that the total iovec from the client doesn't overflow iov_length() but it only checked the first element. The iovec could still overflow by starting with a small element. The obvious fix is to check all the elements. The overflow case doesn't look dangerous to the kernel as the copy is limited by the length after the overflow. This fix restores the intention of returning an error instead of successfully copying less than the iovec represented. I found this by code inspection. I built it but don't have a test case.

2012-08-06drm/i915: Workaround hang with BSD and forcewake on SandyBridgeChris Wilson1-9/+10
For reasons that are not apparent to anybody, 990bbdadaba (drm/i915: Group the GT routines together in both code and vtable) breaks the use of the BitStream Decoder ring on SandyBridge. The active ingredient of that patch is the conversion from a udelay(10) to a udelay(1) in the busy-wait loop of waiting for the forcewake acknowledge. If we restore that udelay(10) or insert another udelay(1) afterwards (or any wait longer than 250ns) everything works again. An alternative is also to remove any delay from the busy-wait loop. Given that in the atomic sections we want to complete the wait as quick as possible to avoid blocking the CPU for too long, it makes sense to remove the delay altogether and simply spin on the exit condition until it completes. So we replace the udelay(1) with cpu_relax().

2012-08-05GPIO: gpio-pxa: fix devicetree functionsDaniel Mack1-0/+26
Provide an of_xlate function for the PXA GPIO chips and make it work for devicetree environments. Successfully tested on a PXA3xx board. Signed-off-by: Daniel Mack <[email protected]> Acked-by: Haojian Zhuang <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
2012-08-05gpio: msic: Fix calculating register address in msic_gpio_to_oreg()Axel Lin1-1/+1
In the case offset is 20 ... 23, the equation to get the register should be: INTEL_MSIC_GPIO1HV0CTLO - offset + 20 With above equation, we can get below mapping between offset and the register: offset is 20: INTEL_MSIC_GPIO1HV0CTLO offset is 21: INTEL_MSIC_GPIO1HV1CTLO offset is 22: INTEL_MSIC_GPIO1HV2CTLO offset is 23: INTEL_MSIC_GPIO1HV3CTLO Signed-off-by: Axel Lin <[email protected]> Acked-by: Mathias Nyman <[email protected]> Signed-off-by: Linus Walleij <[email protected]>

2012-08-05pinctrl/pinctrl-u300: remove unneeded devm_kfree callDevendra Naga1-6/+2
the allocated memory will be destroyed at the driver unload time, automatically if driver uses the devm_ functions, so no need of doing devm_kfree at the error path Signed-off-by: Devendra Naga <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
2012-08-05pinctrl: mxs: register driver at postcore_initcall timeShawn Guo2-2/+2
It's not so usual, but there are still some cases which require pinctrl driver function at arch_initcall time. So register imx23 and imx28 pinctrl driver at postcore_initcall time.
