* usb: dwc3: add support for USB 2.0-only core configurationPaul Zimmerman2014-06-30
| | | | | | | | | | | | | | | Newer DWC3 controllers can be built for USB 2.0-only mode, where most of the USB 3.0 circuitry is left out. To support this mode, the driver must limit the speed programmed into the DCFG register to Hi-Speed or lower. Reads and writes to the PIPECTL register are left as-is, since they should be no-ops in USB 2.0-only mode. Calls to phy_init() etc. for the USB3 phy are also left as-is, since the no-op USB3 phy should be used for USB 2.0-only mode controllers.

| * ARM: 8087/1: ptrace: reload syscall number after secure_computing() checkWill Deacon2014-06-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the syscall tracing path, we call out to secure_computing() to allow seccomp to check the syscall number being attempted. As part of this, a SIGTRAP may be sent to the tracer and the syscall could be re-written by a subsequent SET_SYSCALL ptrace request. Unfortunately, this new syscall is ignored by the current code unless TIF_SYSCALL_TRACE is also set on the current thread. This patch slightly reworks the enter path of the syscall tracing code so that we always reload the syscall number from current_thread_info()->syscall after the potential ptrace traps.

| * ARM: 8076/1: mm: add support for HW coherent systems in PL310 cacheThomas Petazzoni2014-06-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a PL310 cache is used on a system that provides hardware coherency, the outer cache sync operation is useless, and can be skipped. Moreover, on some systems, it is harmful as it causes deadlocks between the Marvell coherency mechanism, the Marvell PCIe controller and the Cortex-A9. To avoid this, this commit introduces a new Device Tree property 'arm,io-coherent' for the L2 cache controller node, valid only for the PL310 cache. It identifies the usage of the PL310 cache in an I/O coherent configuration. Internally, it makes the driver disable the outer cache sync operation. Note that technically speaking, a fully coherent system wouldn't require any of the other .outer_cache operations. However, in practice, when booting secondary CPUs, these are not yet coherent, and therefore a set of cache maintenance operations are necessary at this point. This explains why we keep the other .outer_cache operations and only ->sync is disabled. While in theory any write to a PL310 register could cause the deadlock, in practice, disabling ->sync is sufficient to workaround the deadlock, since the other cache maintenance operations are only used in very specific situations. Contrary to previous versions of this patch, this new version does not simply NULL-ify the ->sync member, because the l2c_init_data structures are now 'const' and therefore cannot be modified, which is a good thing. Therefore, this patch introduces a separate l2c_init_data instance, called of_l2c310_coherent_data.

This change makes the LCD panel and HDMI work again on the NVIDIA Dalmore board anyway.

However, these depend on valid enable_reg, enable_mask and enable_value in regulator descriptor. Currently we do not populate these for SMPS other than SMPS10, this results in spurious results as regmap assumes that the values are valid and ends up reading register 0x0 RTC:SECONDS_REG on Palmas variants that do have RTC! To fix this, we update proper parameters for the descriptor fields. Further, we want to ensure the behavior consistent with logic prior to commit dbabd624d4eec50b6, where, once you do a set_mode, enable/disable ensure the logic remains consistent and configures Palmas to the configuration that we set with set_mode (since the configuration register is common). To do this, we can rely on the regulator core's regulator_register behavior where the regulator descriptor pointer provided by the regulator driver is stored. (no reallocation and copy is done). This lets us update the enable_value post registration, to remain consistent with the mode we configure as part of set_mode.
