2013-06-24usb: chipidea: drop "13xxx" infixAlexander Shishkin14-260/+261
"ci13xxx" is bad for at least the following reasons: * people often mistype it * it doesn't add any informational value to the names it's used in * it needlessly attracts mail filters This patch replaces it with "ci_hdrc", "ci_udc" or "ci_hw", depending on the situation. Modules with ci13xxx prefix are also renamed accordingly and aliases are added for compatibility. Otherwise, no functional changes.

By enabling CONFIG_MEDIA_ATTACH, the configuration becomes valid, as dvb_attach() macro loads the module if needed, making the symbol available to the builtin module. While this bug started to appear after the patches that use IS_DEFINED macro (like changeset 7b34be71db533f3e0cf93d53cf62d036cdb5418a), this bug is a way ancient than that. The thing is that, before the IS_DEFINED() patches, the logic used to be: && defined(MODULE)) struct dvb_frontend *zl10039_attach(struct dvb_frontend *fe, u8 i2c_addr, struct i2c_adapter *i2c); static inline struct dvb_frontend *zl10039_attach(struct dvb_frontend *fe, u8 i2c_addr, struct i2c_adapter *i2c) { printk(KERN_WARNING "%s: driver disabled by Kconfig\n", __func__); return NULL; } The above code, with the .config file used, was evoluting to FALSE (instead of TRUE as it should be, as CONFIG_DVB_ZL10039 is 'm'), and were adding the static inline code at saa7134-dvb, instead of the external call. So, while it weren't producing any compilation error, the code weren't working either. So, as the overhead for using CONFIG_MEDIA_ATTACH is minimal, just enable it, if MODULES is defined.

2013-06-20irqchip: gic: call gic_cpu_init() as well in CPU_STARTING_FROZEN caseShawn Guo1-1/+1
Commit c011470 (irqchip: gic: Perform the gic_secondary_init() call via CPU notifier) moves gic_secondary_init() that used to be called in .smp_secondary_init hook into a notifier call. But it changes the system behavior a little bit. Before the commit, gic_cpu_init() is called not only when kernel brings up the secondary cores but also when system resuming procedure hot-plugs the cores back to kernel. While after the commit, the function will not be called in the latter case, where the 'action' will not be CPU_STARTING but CPU_STARTING_FROZEN. This behavior difference at least causes the following suspend/resume regression on imx6q. $ echo mem > /sys/power/state PM: Syncing filesystems ... done.

2013-06-20ACPI / LPSS: Power up LPSS devices during enumerationRafael J. Wysocki2-6/+35
Commit 7cd8407 (ACPI / PM: Do not execute _PS0 for devices without _PSC during initialization) introduced a regression on some systems with Intel Lynxpoint Low-Power Subsystem (LPSS) where some devices need to be powered up during initialization, but their device objects in the ACPI namespace have _PS0 and _PS3 only (without _PSC or power resources). To work around this problem, make the ACPI LPSS driver power up devices it knows about by using a new helper function acpi_device_fix_up_power() that does all of the necessary sanity checks and calls acpi_dev_pm_explicit_set() to put the device into D0.

2013-06-20ACPI / PM: Fix error code path for power resources initializationRafael J. Wysocki1-0/+1
Commit 781d737 (ACPI: Drop power resources driver) introduced a bug in the power resources initialization error code path causing a NULL pointer to be referenced in acpi_release_power_resource() if there's an error triggering a jump to the 'err' label in acpi_add_power_resource(). This happens because the list_node field of struct acpi_power_resource has not been initialized yet at this point and doing a list_del() on it is a bad idea. To prevent this problem from occuring, initialize the list_node field of struct acpi_power_resource upfront.

2013-06-19ACPI / resources: call acpi_get_override_irq() only for legacy IRQ resourcesMika Westerberg1-5/+11
acpi_get_override_irq() was added because there was a problem with buggy BIOSes passing wrong IRQ() resource for the RTC IRQ. The commit that added the workaround was 61fd47e0c8476 (ACPI: fix two IRQ8 issues in IOAPIC mode). With ACPI 5 enumerated devices there are typically one or more extended IRQ resources per device (and these IRQs can be shared). However, the acpi_get_override_irq() workaround forces all IRQs in range 0 - 15 (the legacy ISA IRQs) to be edge triggered, active high as can be seen from the dmesg below: ACPI: IRQ 6 override to edge, high ACPI: IRQ 7 override to edge, high ACPI: IRQ 7 override to edge, high ACPI: IRQ 13 override to edge, high Also /proc/interrupts for the I2C controllers (INT33C2 and INT33C3) shows the same thing: 7: 4 0 0 0 IO-APIC-edge INT33C2:00, INT33C3:00 The _CSR method for INT33C2 (and INT33C3) device returns following resource: Interrupt (ResourceConsumer, Level, ActiveLow, Shared,,, ) { 0x00000007, } which states that this is supposed to be level triggered, active low, shared IRQ instead. Fix this by making sure that acpi_get_override_irq() gets only called when we are dealing with legacy IRQ() or IRQNoFlags() descriptors. While we are there, correct pr_warning() to print the right triggering value. This change turns out to be necessary to make DMA work correctly on systems based on the Intel Lynxpoint PCH (Platform Controller Hub).

It adds code to gracefully handle failures by returning standard error values, and changing the driver to handle those failure cases. These are against Greg's usb-next branch, and are not marked for stable. Please queue for 3.11. Sarah Sharp

2013-06-17USB: EHCI: tegra: Fix oops in error cleanupThierry Reding1-3/+3
Under some circumstances it happens that the connected PHY can't be powered up properly, in which case the cleanup path currently crashes because it checks the tegra->transceiver field using !IS_ERR(), which will succeed because it is in fact NULL. Dereferencing that pointer causes an oops in tegra_ehci_probe(). This patch fixes the issue by adding an additional label into the cleanup path to separately take down the PHY and the transceiver.

2013-06-17USB: EHCI: tegra: fix circular module dependenciesStephen Warren2-39/+36
The Tegra EHCI driver directly calls various functions in the Tegra USB PHY driver. The reverse is also true; the PHY driver calls into the EHCI driver. This is problematic when the two are built as modules. The calls from the PHY to EHCI driver were originally added in commit bbdabdb "usb: add APIs to access host registers from Tegra PHY", for the following reasons: 1) The register being touched is an EHCI register, so logically only the EHCI driver should touch it. 2) (1) implies that some locking may be needed to correctly implement the r/m/w access to this shared register. 3) We were expecting to pass only the PHY register space to the Tegra PHY driver, and hence it would not have access to touch the shared registers. To solve this, that commit added functions in the EHCI driver to touch the shared register on behalf of the PHY driver. In practice, we ended up not having any locking in the implementaiton of those functions, and I've been led to believe this is safe. Equally, (3) did not happen either. Hence, it is possible for the PHY driver to touch the shared register directly. Given that, this patch moves the code to touch the shared register back into the PHY driver, to eliminate the module problems. If we actually need locking or co-ordination in the future, I propose we put the lock support into some pre-existing core module, or into a third separate module, in order to avoid the circular dependencies. I apologize for my contribution to code churn here.

2013-06-17USB: EHCI: tegra: remove all power managementStephen Warren1-245/+1
The PM routines in ehci-tegra.c use APIs such as ehci_reset(), ehci_halt(), and ehci_tdi_reset() that would need to be exported to convert ehci-tegra.c into a separate module from ehci-hcd.c. However, we'd prefer not to export them. Instead, simply remove all power management functionality. Runtime PM was disabled since it didn't work correctly, and system suspend isn't yet supported in a meaningful way. So, this change doesn't lose any functionality. Hopefully the power management logic can be reimplemented in a cleaner way in the future.
