2016-06-02stmmac: do not sleep in atomic context for mdio_resetVincent Palatin
stmmac_mdio_reset() has been updated to use msleep rather udelay (as some PHY requires a one second delay there). It called from stmmac_resume() within the spin_lock_irqsave block atomic context triggering 'scheduling while atomic'. The stmmac_priv lock usage is not fully documented, but it seems to protect the access to the MAC registers / DMA structures rather than the MDIO bus or the PHY (which have separate locking), so we can push the spin_lock after the stmmac_mdio_reset call.

2016-06-02drm: hdlcd: Revamp runtime power managementLiviu Dudau
Because the HDLCD driver acts as a component master it can end up enabling the runtime PM functionality before the encoders are initialised. This can cause crashes if the component slave never probes (missing module) or if the PM operations kick in before the probe finishes. Move the enabling of the runtime PM after the component master has finished collecting the slave components and use the DRM atomic helpers to suspend and resume the device.

The MMC clock timings were incorrectly calculated, when the conversion from delay value to delay phase was done. The 50M DDR and 50M DDR 8bit timings are off, and make eMMC DDR unusable. Unfortunately it seems different controllers on the same SoC have different timings. The new settings are taken from mmc2, which is commonly used with eMMC. The settings for the slower timing modes seem to work despite being wrong, so leave them be.

When IS_ERR_VALUE was removed from the mmc core code, it was replaced with a simple not-zero check. This does not work, as the value checked is the return value for mmc_select_bus_width, which returns the set bit width on success. This made eMMC modes higher than HS-DDR unusable. Fix this by checking for a positive return value instead.

gcc warns about qed_fill_link possibly accessing uninitialized data: drivers/net/ethernet/qlogic/qed/qed_main.c: In function 'qed_fill_link': drivers/net/ethernet/qlogic/qed/qed_main.c:1170:35: error: 'link_caps' may be used uninitialized in this function [-Werror=maybe-uninitialized] While this warning is only about the specific case of CONFIG_QED_SRIOV being disabled but the function getting called for a VF (which should never happen), another possibility is that qed_mcp_get_*() fails without returning data. This rearranges the code so we bail out in either of the two cases and print a warning instead of accessing the uninitialized data. The qed_link_output structure remains untouched in this case, but all callers first call memset() on it, so at least we are not leaking stack data then. As discussed, we also use a compile-time check to ensure we never use any of the VF code if CONFIG_QED_SRIOV is disabled, and the PCI device table is updated to no longer bind to virtual functions in that configuration.

2016-06-02ACPI / processor: Avoid reserving IO regions too earlyRafael J. Wysocki
Roland Dreier reports that one of his systems cannot boot because of the changes made by commit ac212b6980d8 (ACPI / processor: Use common hotplug infrastructure). The problematic part of it is the request_region() call in acpi_processor_get_info() that used to run at module init time before the above commit and now it runs much earlier. Unfortunately, the region(s) reserved by it fall into a range the PCI subsystem attempts to reserve for AHCI IO BARs. As a result, the PCI reservation fails and AHCI doesn't work, while previously the PCI reservation would be made before acpi_processor_get_info() and it would succeed. That request_region() call, however, was overlooked by commit ac212b6980d8, as it is not necessary for the enumeration of the processors. It only is needed when the ACPI processor driver actually attempts to handle them which doesn't happen before loading the ACPI processor driver module. Therefore that call should have been moved from acpi_processor_get_info() into that module. Address the problem by moving the request_region() call in question out of acpi_processor_get_info() and use the observation that the region reserved by it is only needed if the FADT-based CPU throttling method is going to be used, which means that it should be sufficient to invoke it from acpi_processor_get_throttling_fadt().

At least on n900 we have phy-twl4030-usb only generating cable interrupts, and then have a separate USB PHY. In order for musb to know the real cable status, we need to clear any cached state until musb is ready. Otherwise the cable status interrupts will get just ignored if the status does not change from the initial state. To do this, let's add a return value to musb_mailbox(), and reset cached linkstat to MUSB_UNKNOWN on error.

2016-06-01usb: musb: sunxi: Set state to A_WAIT_VRISE when enabling VbusHans de Goede
When the board is powering attached usb devices via the otg port sometimes / on some devices it takes slightly too long for the Vbus detection code in phy-sun4i-usb.c to signal that Vbus is high after enabling Vbus and the musb hardware signals a MUSB_INTR_VBUSERROR interrupt. This commit sets the otg state to A_WAIT_VRISE upon enabling Vbus making musb_stage0_irq() ignore the first VBUSERR_RETRY_COUNT VBUSERROR interrupts, fixing connection issues in these cases.

2016-06-01usb: musb: host: make musb_tx_dma_set_mode_*() *void*Sergei Shtylyov
Now that the DMA engine check was moved to musb_tx_dma_porgram(), both musb_tx_dma_set_mode_cppi_tusb() and musb_tx_dma_set_mode_mentor() always return 0, so we can make both these functions *void*.

2016-06-01usb: musb: host: move DMA engine check from musb_tx_dma_set_mode_cppi_tusb() ↵Sergei Shtylyov
to its caller Commit 754fe4a92c07 ("usb: musb: Remove ifdefs for TX DMA for musb_host.c") looks incomplete: the DMA engine checks are done outside the Mentor/UX500 handler but inside the CPPI/TUSB handler. Move the checks out of the CPPI/ TUSB handler into its caller, musb_tx_dma_program().
