git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt Pull "reworked dts changes for ti81xx devices and minimal dra62x j5ec-evm support" from Tony Lindgren: Add minimal device tree support for dra62x also known j5eco. It is related to dm814x, just the clocks are a bit different and it has a different set of integrated devices. And let's get some basic dm814x and dra62x devices working as many of the devices are like on am33xx:: - pinctrl using the pinctrl defines as for am33xx - Updated EDMA bindings with support for using exma_xbar - MMC support for dm814x-evm, t410 and dra62x-j5eco-evm - USB support for dm814x-evm, t410 and dra62x-j5eco-evm This branch depends on an earlier omap-for-v4.5/81xx-fixes-signed branch that has dm814x dts fixes interlaced with SoC related fixes to keep things booting. The interlaced SoC and dts fixes were needed because of issues with the device tree defined clocks that just happened to work on bootloader timings for t410 earlier. * tag 'omap-for-v4.5/81xx-dts-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (21 commits) ARM: dts: Add usb support for j5-eco evm ARM: dts: Add usb support for hp t410 ARM: dts: Add usb support for dm814x-evm ARM: dts: Add usb support for dm814x and dra62x ARM: dts: Enable emmc on hp t410 ARM: dts: Add mmc support for dra62x j5-eco evm ARM: dts: Add mmc support for dm8148-evm ARM: dts: Add mmc device entries for dm814x ARM: dts: Update edma bindings on dm814x to use edma_xbar ARM: dts: Add pinctrl macros for dm814x ARM: dts: Add minimal dra62x j5-eco evm support ARM: dts: Add basic support for dra62x j5-eco SoC ARM: OMAP2+: Remove useless check for legacy booting for dm814x ARM: OMAP2+: Enable GPIO for dm814x ARM: dts: Fix dm814x pinctrl address and mask ARM: dts: Fix dm8148 control modules ranges ARM: OMAP2+: Fix timer entries for dm814x ARM: dts: Fix some mux and divider clocks to get dm814x-evm booting ARM: OMAP2+: Add DPPLS clock manager for dm814x clk: ti: Add few dm814x clock aliases ...

2015-12-02ARM: imx: clk-vf610: fix SAI clock treeStefan Agner
The Synchronous Audio Interface (SAI) instances are clocked by independent clocks: The bus clock and the audio clock (as shown in Figure 51-1 in the Vybrid Reference Manual). The clock gates in CCGR0/CCGR1 for SAI0 through SAI3 are bus clock gates, as access tests to the registers with/without gating those clocks have shown. The audio clock is gated by the SAIx_EN gates in CCM_CSCDR1, followed by a clock divider (SAIx_DIV). Currently, the parent of the bus clock gates has been assigned to SAIx_DIV, which is not involved in the bus clock path for the SAI instances (see chapter 9.10.12, SAI clocking in the Vybrid Reference Manual). Fix this by define the parent clock of VF610_CLK_SAIx to be the bus clock. If the driver needs the audio clock (when used in master mode), a fixed device tree is required which assign the audio clock properly to VF610_CLK_SAIx_DIV.

2015-11-28target: fix COMPARE_AND_WRITE non zero SGL offset data corruptionJan Engelhardt
target_core_sbc's compare_and_write functionality suffers from taking data at the wrong memory location when writing a CAW request to disk when a SGL offset is non-zero. This can happen with loopback and vhost-scsi fabric drivers when SCF_PASSTHROUGH_SG_TO_MEM_NOALLOC is used to map existing user-space SGL memory into COMPARE_AND_WRITE READ/WRITE payload buffers. Given the following sample LIO subtopology, % targetcli ls /loopback/ o- loopback ................................. [1 Target] o- naa.6001405ebb8df14a .......

2015-11-28target: Fix race for SCF_COMPARE_AND_WRITE_POST checkingNicholas Bellinger
This patch addresses a race + use after free where the first stage of COMPARE_AND_WRITE in compare_and_write_callback() is rescheduled after the backend sends the secondary WRITE, resulting in second stage compare_and_write_post() callback completing in target_complete_ok_work() before the first can return. Because current code depends on checking se_cmd->se_cmd_flags after return from se_cmd->transport_complete_callback(), this results in first stage having SCF_COMPARE_AND_WRITE_POST set, which incorrectly falls through into second stage CAW processing code, eventually triggering a NULL pointer dereference due to use after free. To address this bug, pass in a new *post_ret parameter into se_cmd->transport_complete_callback(), and depend upon this value instead of ->se_cmd_flags to determine when to return or fall through into ->queue_status() code for CAW.

This patch addresses a case where iscsi_target_do_tx_login_io() fails sending the last login response PDU, after the RX/TX threads have already been started. The case centers around iscsi_target_rx_thread() not invoking allow_signal(SIGINT) before the send_sig(SIGINT, ...) occurs from the failure path, resulting in RX thread hanging indefinately on iscsi_conn->rx_login_comp.

2015-11-26xen/evtchn: dynamically grow pending event channel ringDavid Vrabel
If more than 1024 event channels are bound to a evtchn device then it possible (even with well behaved applications) for the ring to overflow and events to be lost (reported as an -EFBIG error). Dynamically increase the size of the ring so there is always enough space for all bound events. Well behaved applicables that only unmask events after draining them from the ring can thus no longer lose events. However, an application could unmask an event before draining it, allowing multiple entries per port to accumulate in the ring, and a overflow could still occur. So the overflow detection and reporting is retained. The ring size is initially only 64 entries so the common use case of an application only binding a few events will use less memory than before. The ring size may grow to 512 KiB (enough for all 2^17 possible channels). This order 7 kmalloc() may fail due to memory fragmentation, so we fall back to trying vmalloc().

2015-11-26xen/events: Always allocate legacy interrupts on PV guestsBoris Ostrovsky
After commit 8c058b0b9c34 ("x86/irq: Probe for PIC presence before allocating descs for legacy IRQs") early_irq_init() will no longer preallocate descriptors for legacy interrupts if PIC does not exist, which is the case for Xen PV guests. Therefore we may need to allocate those descriptors ourselves.

2015-11-26xen/gntdev: Grant maps should not be subject to NUMA balancingBoris Ostrovsky
Doing so will cause the grant to be unmapped and then, during fault handling, the fault to be mistakenly treated as NUMA hint fault. In addition, even if those maps could partcipate in NUMA balancing, it wouldn't provide any benefit since we are unable to determine physical page's node (even if/when VNUMA is implemented). Marking grant maps' VMAs as VM_IO will exclude them from being part of NUMA balancing.

2015-11-26rtc: ds1307: fix alarm reading at probe timeSimon Guinot
With the actual code, read_alarm() always returns -EINVAL when called during the RTC device registration. This prevents from retrieving an already configured alarm in hardware. This patch fixes the issue by moving the HAS_ALARM bit configuration (if supported by the hardware) above the rtc_device_register() call.

Commit b3a72384fe29 ("ARM/PCI: Replace pci_sys_data->align_resource with global function pointer") introduced an ARM-specific align_resource() function pointer. This is not portable to other arches and doesn't work for platforms with two different PCIe host bridge controllers. Move the function pointer to the pci_host_bridge structure so each host bridge driver can specify its own align_resource() function.

2015-11-25rtc: ds1307: fix kernel splat due to wakeup irq handlingFelipe Balbi
Since commit 3fffd1283927 ("i2c: allow specifying separate wakeup interrupt in device tree") we have automatic wakeup irq support for i2c devices. That commit missed the fact that rtc-1307 had its own wakeup irq handling and ended up introducing a kernel splat for at least Beagle x15 boards. Fix that by reverting original commit _and_ passing correct interrupt names on DTS so i2c-core can choose correct IRQ as wakeup. Now that we have automatic wakeirq support, we can revert the original commit which did it manually. Fixes the following warning: [ 10.346582] WARNING: CPU: 1 PID: 263 at linux/drivers/base/power/wakeirq.c:43 dev_pm_attach_wake_irq+0xbc/0xd4() [ 10.359244] rtc-ds1307 2-006f: wake irq already initialized Cc: Tony Lindgren <tony@atomide.com> Cc: Nishanth Menon <nm@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com> Acked-by: Tony Lindgren <tony@atomide.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
