2016-06-30mfd: max77620: Fix FPS switch statementsRhyland Klein
When configuring FPS during probe, assuming a DT node is present for FPS, the code can run into a problem with the switch statements in max77620_config_fps() and max77620_get_fps_period_reg_value(). Namely, in the case of chip->chip_id == MAX77620, it will set fps_[mix|max]_period but then fall through to the default switch case and return -EINVAL. Returning this from max77620_config_fps() will cause probe to fail.

2016-06-29ACPI: Execute _PTS before system rebootOcean He
The _PTS control method is defined in the section 7.4.1 of acpi 6.0 spec. The _PTS control method is executed by the OS during the sleep transition process for S1, S2, S3, S4, and for orderly S5 shutdown. The _PTS control method provides the BIOS a mechanism for performing some housekeeping, such as writing the sleep type value to the embedded controller, before entering the system sleeping state. Note that some Lenovo Server BIOS use this mechanism to detect reboot event and prompt user by popped dialog box. According to section 7.5 of acpi 6.0 spec, _PTS should run after _TTS. Add a _PTS evaulation to the existing _TTS reboot notifier and change the notifier name to reflect the fact that it's not for _TTS only any more.

2016-06-29ACPI / APEI: Add Boot Error Record Table (BERT) supportHuang Ying
ACPI/APEI is designed to verifiy/report H/W errors, like Corrected Error(CE) and Uncorrected Error(UC). It contains four tables: HEST, ERST, EINJ and BERT. The first three tables have been merged for a long time, but because of lacking BIOS support for BERT, the support for BERT is pending until now. Recently on ARM 64 platform it is has been supported. So here we come. Under normal circumstances, when a hardware error occurs, kernel will be notified via NMI, MCE or some other method, then kernel will process the error condition, report it, and recover it if possible. But sometime, the situation is so bad, so that firmware may choose to reset directly without notifying Linux kernel. Linux kernel can use the Boot Error Record Table (BERT) to get the un-notified hardware errors that occurred in a previous boot. In this patch, the error information is reported via printk. For more information about BERT, please refer to ACPI Specification version 6.0, section 18.3.1: http://www.uefi.org/sites/default/files/resources/ACPI_6.0.pdf The following log is a BERT record after system reboot because of hitting a fatal memory error: BERT: Error records from previous boot: [Hardware Error]: It has been corrected by h/w and requires no further action [Hardware Error]: event severity: corrected [Hardware Error]: Error 0, type: recoverable [Hardware Error]: section_type: memory error [Hardware Error]: error_status: 0x0000000000000400 [Hardware Error]: physical_address: 0xffffffffffffffff [Hardware Error]: card: 1 module: 2 bank: 3 row: 1 column: 2 bit_position: 5 [Hardware Error]: error_type: 2, single-bit ECC [Tomasz Nowicki: Clear error status at the end of error handling] [Tony: Applied some cleanups suggested by Fu Wei] [Fu Wei: delete EXPORT_SYMBOL_GPL(bert_disable), improve the code] Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Tomasz Nowicki <tomasz.nowicki@linaro.org> Signed-off-by: Chen, Gong <gong.chen@linux.intel.com> Tested-by: Jonathan (Zhixiong) Zhang <zjzhang@codeaurora.org> Signed-off-by: Fu Wei <fu.wei@linaro.org> Tested-by: Tyler Baicar <tbaicar@codeaurora.org> Reviewed-by: Borislav Petkov <bp@suse.de> Signed-off-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Rafael J.

2016-06-29igb: Only DMA sync frame lengthAndrew Lunn
On some platforms, syncing a buffer for DMA is expensive. Rather than sync the whole 2K receive buffer, only synchronise the length of the frame, which will typically be the MTU, or a much smaller TCP ACK. For an IMX6Q, this gives around 6% increased TCP receive performance, which is cache operations bound and reduces CPU load for TCP transmit.

2016-06-29reset: Ensure drivers are explicit when requesting reset linesLee Jones
Phasing out generic reset line requests enables us to make some better decisions on when and how to (de)assert said lines. If an 'exclusive' line is requested, we know a device *requires* a reset and that it's preferable to act upon a request right away. However, if a 'shared' reset line is requested, we can reasonably assume sure that placing a device into reset isn't a hard requirement, but probably a measure to save power and is thus able to cope with not being asserted if another device is still in use. In order allow gentle adoption and not to forcing all consumers to move to the API immediately, causing administration headache between subsystems, this patch adds some temporary stand-in shim-calls. This will ease the burden at merge time and allow subsystems to migrate over to the new API in a more realistic time-frame.

2016-06-29regmap: Support bulk writes for devices without raw formattingChen-Yu Tsai
When doing a bulk writes from a device which lacks raw I/O support we fall back to doing register at a time reads but we still use the raw formatters in order to render the data into the word size used by the device (since bulk reads still operate on the device word size rather than unsigned ints). This means that devices without raw formatting such as those that provide reg_read() are not supported. Provide handling for them by copying the values read into native endian values of the appropriate size.

The i.MX51 datasheet says: Chapter 56.1.2.4 I2S Mode ... When I2S modes are entered (I2S master (01) or I2S slave (10)), the following settings are recommended: ... - TX Frame Rate should be 2 i.e. (STCCR[12:8] = 1) - RX Frame Rate should be 2 i.e. (SRCCR[12:8] = 1) Chapter 56.3.3.12 SSI Transmit and Receive Clock Control Registers (STCCR & SRCCR) ... Bits 12-8 DC4-DC0 Frame Rate Divider Control. These bits are used to control the divide ratio for the programmable frame rate dividers. The divide ratio works on the word clock. In Normal mode, this ratio determines the word transfer rate. In Network mode, this ratio sets the number of words per frame. The divide ratio ranges from 1 to 32 in Normal mode and from 2 to 32 in Network mode. In Normal mode, a divide ratio of 1 (DC=00000) provides continuous periodic data word transfer. A bit-length frame sync must be used in this case. Function fsl_ssi_hw_params() setup Normal mode for MONO output, so with DC=0, SSI enters to continuous periodic data word transfer. To fix this, setup DC for any I2S mode. Patch has tested on custom board based on Digi CCMX-51 module (i.MX51).

2016-06-29fm10k: Remove create_workqueueBhaktipriya Shridhar
alloc_workqueue replaces deprecated create_workqueue(). A dedicated workqueue has been used since the workitem (viz fm10k_service_task, which manages and runs other subtasks) is involved in normal device operation and requires forward progress under memory pressure. create_workqueue has been replaced with alloc_workqueue with max_active as 0 since there is no need for throttling the number of active work items. Since network devices may be used in memory reclaim path, WQ_MEM_RECLAIM has been set to guarantee forward progress. flush_workqueue is unnecessary since destroy_workqueue() itself calls drain_workqueue() which flushes repeatedly till the workqueue becomes empty. Hence the call to flush_workqueue() has been dropped.

Properly stop the extra workqueue items and ensure that we resume cleanly. This is better than using igb_ptp_init and igb_ptp_stop since these functions destroy the PHC device, which will cause other problems if we do so. Since igb_ptp_reset now re-schedules the work-queue item we don't need an equivalent igb_ptp_resume in the resume workflow.

In total, resetting the TSAUXC register, and resetting the system time both happen in igb_ptp_reset already. igb_ptp_reset now also takes care of starting the delayed work item for overflow checks, as well.

2016-06-29e1000e: prevent division by zero if TIMINCA is zeroDenys Vlasenko
Users report that under VMWare, er32(TIMINCA) returns zero. This causes division by zero at init time as follows: ==> incvalue = er32(TIMINCA) & E1000_TIMINCA_INCVALUE_MASK; for (i = 0; i < E1000_MAX_82574_SYSTIM_REREADS; i++) { /* latch SYSTIMH on read of SYSTIML */ systim_next = (cycle_t)er32(SYSTIML); systim_next |= (cycle_t)er32(SYSTIMH) << 32; time_delta = systim_next - systim; temp = time_delta; ====> rem = do_div(temp, incvalue); This change makes kernel survive this, and users report that NIC does work after this change. Since on real hardware incvalue is never zero, this should not affect real hardware use case.

This time around with 109 non-merge commits mostly concentrated on drivers/usb/gadget/udc (41.5%) and drivers/usb/dwc3 (28.1%). There's a big rework on dwc3's transfer handling which gave us almost 3x faster USB3 speeds with Mass Storage on a particular test scenario I measured. We are also removing platform_data from dwc3 after converting all users to built-in properties instead. For the Gadget API, we're just adding tracepoints to aid debugging activities. Other than these, there's the usual set of spelling fixes, minor bug fixes and sparse warnings cleanups.
2016-06-29Input: add SW_PEN_INSERTED defineDouglas Anderson
Some devices with a pen may have a switch that can be used to detect when the pen is inserted or removed to a slot on the device. Let's add a define to the input event codes so that everyone can be on the same page for what event we should generate when the pen is inserted or removed. In general the pen switch could be used by the software on the device to kick off any number of actions when the pen is inserted or removed.
