2017-12-13net: phy: fix resume handlingRussell King
When a PHY has the BMCR_PDOWN bit set, it may decide to ignore writes to other registers, or reset the registers to power-on defaults. Micrel PHYs do this for their interrupt registers. The current structure of phylib tries to enable interrupts before resuming (and releasing) the BMCR_PDOWN bit. This fails, causing Micrel PHYs to stop working after a suspend/resume sequence if they are using interrupts. Fix this by ensuring that the PHY driver resume methods do not take the phydev->lock mutex themselves, but the callers of phy_resume() take that lock. This then allows us to move the call to phy_resume() before we enable interrupts in phy_start().

2017-12-13drm: Update edid-derived drm_display_info fields at edid property set [v2]Keith Packard
There are a set of values in the drm_display_info structure for each connector which hold information derived from EDID. These are computed in drm_add_display_info. Before this patch, that was only called in drm_add_edid_modes. This meant that they were only set when EDID was present and never reset when EDID was not, as happened when the display was disconnected. One of these fields, non_desktop, is used from drm_mode_connector_update_edid_property, the function responsible for assigning the new edid value to the application-visible property. Various drivers call these two functions (drm_add_edid_modes and drm_mode_connector_update_edid_property) in different orders. This means that even when EDID is present, the drm_display_info fields may not have been computed at the time that drm_mode_connector_update_edid_property used the non_desktop value to set the non_desktop property. I've added a public function (drm_reset_display_info) that resets the drm_display_info field values to default values and then made the drm_add_display_info function public. These two functions are now called directly from drm_mode_connector_update_edid_property so that the drm_display_info fields are always computed from the current EDID information before being used in that function. This means that the drm_display_info values are often computed twice, once when the EDID property it set and a second time when EDID is used to compute modes for the device. The alternative would be to uniformly ensure that the values were computed once before being used, which would require that all drivers reliably invoke the two paths in the same order. The computation is inexpensive enough that it seems more maintainable in the long term to simply compute them in both paths. The API to drm_add_display_info has been changed so that it no longer takes the set of edid-based quirks as a parameter. Rather, it now computes those quirks itself and returns them for further use by drm_add_edid_modes. This patch also includes a number of 'const' additions caused by drm_mode_connector_update_edid_property taking a 'const struct edid *' parameter and wanting to pass that along to drm_add_display_info. v2: after review by Daniel Vetter <daniel.vetter@ffwll.ch> Removed EXPORT_SYMBOL_GPL for drm_reset_display_info and drm_add_display_info. Added FIXME in drm_mode_connector_update_edid_property about potentially merging that with drm_add_edid_modes to avoid the need for two driver calls.

2017-12-13staging: fsl-mc: do not print error in case of defer probe errorNipun Gupta
Devices on MC bus can be deferred because of dependencies on other modules (such as IOMMU). Those are not the actual errors; as probing is again done by the kernel at later stages. So this patch avoids the error print in such case. Signed-off-by: Nipun Gupta <nipun.gupta@nxp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-12-13staging: fsl-mc: Allocate IRQ's before scanning DPRC objectsNipun Gupta
Following is the current scenario when the devices are probed: FSL_MC Bus probe ---> dprc probe ---> dprc devices scan ---> probe devices in DPRC container ---> allocate IRQ's In case the devices being probed in the DPRC container need the IRQ's; probing of that device will fail. In current scenario the devices which need IRQ's such as DPIO gets deferred because they aren't registered when first time the probing of these devices is done in the dprc scan. So they are probed once IRQ's have been allocated. In case where DPRC probing itself gets deferred, which does in case IOMMU is enabled; all the devices in DPRC container gets probed before IRQ's are allocated. This causes devices using IRQ's (such as DPIO) to fail. So having IRQ's allocated before any of the devices in the DPRC container are probed is more legitimate. After this patch following is the flow of execution: FSL_MC Bus probe ---> dprc probe ---> dprc devices scan ---> allocate IRQ's ---> probe of devices in DPRC container.

The FIPS manager files were using a naming convention which was inconsistent (ssi vs. cc) and often too long. Make the code more readable by switching to a simpler, consistent naming convention.
