* PM / Kconfig: Replace PM_RUNTIME with PM in dependenciesRafael J. Wysocki2014-12-131-2/+2
| | | | | | | | | | | | | | | After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so Kconfig options depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. Replace PM_RUNTIME with PM in Kconfig dependencies throughout the tree. Signed-off-by: Rafael J.

And that symbol depended on CPU_MMP3 at that time. But CPU_MMP3 has never been part of the tree. This means that this drive was unbuildable when it was added.

USB_PHY is no longer a user visible option. It is upto to the PHY drivers to select it if needed. This patch does so for the existing PHY drivers that use the USB_PHY library. Doing so moves the USB_PHY and PHY driver selection problem from the end user to the PHY and controller driver developer. e.g. Earlier, a controller driver (e.g. EHCI_OMAP) that needs to select a PHY driver (e.g. NOP_PHY) couldn't do so because the PHY driver depended on USB_PHY. Making the controller driver depend on USB_PHY has a negative effect i.e. it becomes invisible to the user till USB_PHY is enabled. Most end users will not familiar with this. With this patch, the end user just needs to select the controller driver needed for his/her platform without worrying about which PHY driver to select. Also update USB_EHCI_MSM, USB_LPC32XX and USB_OMAP to not depend on USB_PHY any more. They can safely select the necessary PHY drivers. [ balbi@ti.com : refreshed on top of my next branch.

* | usb: limit OMAP related USB options to OMAP2PLUS platformsPaul Gortmaker2013-07-261-0/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 57f6ce072e35770a63be0c5d5e82f90d8da7d665 ("usb: phy: add a new driver for usb3 phy") added the new Kconfig option OMAP_USB3, but it had no dependencies whatsoever, and hence became available across all arch/platforms. Which presumably caused this to show up in x86 randconfig: warning: (USB_MUSB_HDRC && OMAP_USB3) selects \ OMAP_CONTROL_USB which has unmet direct \ dependencies (USB_SUPPORT && ARCH_OMAP2PLUS) Then commit 6992819feb39cb9adac72170555d957d07f869f2 ("usb: phy: fix Kconfig warning") was added. However, this just deleted the ARCH_OMAP2PLUS dependency from OMAP_CONTROL_USB, further compounding the problem by opening up OMAP_CONTROL_USB to all arch/platforms as well. Earlier it was suggested[1] that we revert the change of 6992819feb to restore the dependency, and add a same ARCH_OMAP2PLUS dependency to the new OMAP_USB3 entry. However that was discouraged on the grounds of people wanting the extra sanity compile testing on x86, even though the driver could probably never be used there. Now we have CONFIG_COMPILE_TEST, so developers who value the ability to compile drivers on an architecture that it never can be used for can have that, and people who want dependencies to shield them from seeing options that aren't relevant to their platform get what they want too. Here we restore the dependency but couple it with COMPILE_TEST, in order to achieve both of the above goals.

Two new platforms, TI Keystone and Rockchips RK3xxx are added in this branch, both containing almost no platform specific code at all, since they are using generic subsystem interfaces for clocks, pinctrl, interrupts etc. The device drivers are getting merged through the respective subsystem maintainer trees. One more SoC (u300) is now multiplatform capable and several others (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving towards that goal with this series but need more work. Also noteworthy is the work on PCI here, which is traditionally part of the SoC specific code. With the changes done by Thomas Petazzoni, we can now more easily have PCI host controller drivers as loadable modules and keep them separate from the platform code in drivers/pci/host.

Compared to it, R8A7778 USB-PHY has extra register range containing two high-speed signal quality characteristic control registers which should be set up during USB-PHY startup depending on whether a ferrite bead is in use or not. So, we now handle an optional second memory range in the driver's probe method, add the 'ferrite_bead' field to the driver's platform data, and add an extra (optional) step to the USB-PHY startup routine which sets up the extended registers. Also mark in the driver's Kconfig section that R8A7778 is now supported and generally clarify that section, uppercasing the word "phy" and also changing the module name that got lost in the big driver rename, while at it... The patch has been tested on the Marzen and BOCK-W boards.

Many of us have been really busy lately getting multiple drivers to a better position. Since this pull request is so large, I will divide it in sections so it's easier to grasp what's included. - cleanups: . UDC drivers no longer touch gadget->dev, that's now udc-core responsibility . Many more UDC drivers converted to usb_gadget_map/unmap_request() . UDC drivers no longer initialize DMA-related fields from gadget's device structure . UDC drivers don't touch gadget.dev.driver directly . UDC drivers don't assign gadget.dev.release directly . Removal of some unused DMA_ADDR_INVALID . Introduction of CONFIG_USB_PHY . All phy drivers have been moved to drivers/usb/phy and renamed to a common naming scheme . Fix PHY layer so it never returns a NULL pointer, also fix all callers to avoid using IS_ERR_OR_NULL() . Sparse fixes all over the place . drivers/usb/otg/ has been deleted . Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock usage - new features: . UDC core now provides a generic way for tracking and reporting UDC's state (not attached, resuming, suspended, addressed, default, etc) . twl4030-usb learned that it shouldn't be enabled during init . Full DT support for DWC3 has been implemented . ab8500-usb learned about pinctrl framework . nop PHY learned about DeviceTree and regulators . DWC3 learned about suspend/resume . DWC3 can now be compiled in host-only and gadget-only (as well as DRD) configurations . UVC now enables streaming endpoint based on negotiated speed . isp1301 now implements the PHY API properly . configfs-based interface for gadget drivers which will lead to the removal of all code which just combines functions together to build functional gadget drivers. . f_serial and f_obex were converted to new configfs interface while maintaining old interface around. - non-critical fixes: . UVC gadget driver got fixes for Endpoint usage and stream calculation . ab8500-usb fixed unbalanced clock and regulator API usage . twl4030-usb got a fix for when OMAP3 is booted with cable connected . fusb300_udc got a fix for DMA usage . UVC got fixes for two assertions of the USB Video Class Compliance specification revision 1.1 . build warning issues caused by recent addition of __must_check to regulator API These are all changes which deserve a mention, all other changes are related to these one or minor spelling fixes and other similar tasks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this driver compiles fine everywhere which means we can use linux-next to compile it for us frequently. By dropping the arch dependency, we also ensure driver writers don't add virtual arch-depdencies to the driver by e.g. using the wrong headers.
