* phy: miphy365x: Pass sysconfig register offsets via syscfg dt property.Peter Griffin2015-01-111-19/+10
| | | | | | | | | | | | | | | | | | | | Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161, update the miphy365 phy driver to access sysconfig register offsets via syscfg dt property. This is because the reg property should not be mixing address spaces like it does currently for miphy365. This change then also aligns us to how other platforms such as keystone and bcm7445 pass there syscon offsets via DT. This patch breaks DT compatibility, but this platform is considered WIP, and is only used by a few developers who are upstreaming support for it. This change has been done as a single atomic commit to ensure it is bisectable.

* phy: phy-stih407-usb: Pass sysconfig register offsets via syscfg property.Peter Griffin2015-01-111-11/+14
| | | | | | | | | | | | | | | | | | | | | | Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161, update the phy driver to not use the reg property to access the sysconfig register offsets. This is because other phy's (miphy28, miphy365) have a combination of memory mapped registers and sysconfig control regs, and we shouldn't be mixing address spaces in the reg property. In addition we would ideally like the sysconfig offsets to be passed via DT in a uniform way. This new method will also allow us to support devices which have sysconfig registers in different banks more easily and it is also analagous to how keystone and bcm7745 platforms pass there syscon offsets in DT. This breaks DT compatibility, but this platform is considered WIP, and is only used by a few developers who are upstreaming support for it.

Specifics: - Fix a regression in leds-gpio introduced by a recent commit that inadvertently changed the name of one of the properties used by the driver (Fabio Estevam). - Fix a regression in the ACPI backlight driver introduced by a recent fix that missed one special case that had to be taken into account (Aaron Lu). - Drop the level of some new kernel messages from the ACPI core introduced by a recent commit to KERN_DEBUG which they should have used from the start and drop some other unuseful KERN_ERR messages printed by ACPI (Rafael J Wysocki). - Revert an incorrect commit modifying the cpupower tool (Prarit Bhargava). - Fix two regressions introduced by recent commits in the OPP library and clean up some existing minor issues in that code (Viresh Kumar). - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the tree (or drop it where that can be done) in order to make it possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf Hansson, Ludovic Desroches). There will be one more "CONFIG_PM_RUNTIME removal" batch after this one, because some new uses of it have been introduced during the current merge window, but that should be sufficient to finally get rid of it. - Make the ACPI EC driver more robust against race conditions related to GPE handler installation failures (Lv Zheng). - Prevent the ACPI device PM core code from attempting to disable GPEs that it has not enabled which confuses ACPICA and makes it report errors unnecessarily (Rafael J Wysocki). - Add a "force" command line switch to the intel_pstate driver to make it possible to override the blacklisting of some systems in that driver if needed (Ethan Zhao). - Improve intel_pstate code documentation and add a MAINTAINERS entry for it (Kristen Carlson Accardi). - Make the ACPI fan driver create cooling device interfaces witn names that reflect the IDs of the ACPI device objects they are associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B"). That's necessary for user space thermal management tools to be able to connect the fans with the parts of the system they are supposed to be cooling properly.

Most of the commits contained here are sparse or coccinelle fixes ranging from missing 'static' to returning 0 in case of errors. More importantly, we have the removal the now unnecessary 'driver' argument to ->udc_stop(). DWC2 learned about Dual-Role builds. Users of this IP can now have a single driver built for host and device roles. DWC3 got support for two new HW platforms: Exynos7 and AMD. The Broadcom USB 3.0 Device Controller IP is now supported and so is PLX USB338x, which means DWC3 has lost is badge as the only USB 3.0 peripheral IP supported on Linux. Thanks for Tony Lindgren's work, we can now have a distro-like kernel where all MUSB glue layers can be built into the same kernel (statically or dynamically linked) and it'll work in PIO (DMA will come probably on v3.20). Other than these, the usual set of cleanups and non-critical fixes. Signed-off-by: Felipe Balbi <balbi@ti.com>

* phy: phy-mvebu-sata: Add missing error check for devm_kzallocPeter Griffin2014-09-241-0/+2
| | | | | | | | | | | Currently this driver is missing a check on the return value of devm_kzalloc, which would cause a NULL pointer dereference in a OOM situation. This patch adds the aformentioned missing check. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Acked-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

* phy: Renesas R-Car Gen2 PHY driverSergei Shtylyov2014-09-243-0/+349
| | | | | | | | | | | | | | | | | | This PHY, though formally being a part of Renesas USBHS controller, contains the UGCTRL2 register that controls multiplexing of the USB ports (Renesas calls them channels) to the different USB controllers: channel 0 can be connected to either PCI EHCI/OHCI or USBHS controllers, channel 2 can be connected to PCI EHCI/OHCI or xHCI controllers. This is a new driver for this USB PHY currently already supported under drivers/ usb/phy/. The reason for writing the new driver was the requirement that the multiplexing of USB channels to the controller be dynamic, depending on what USB drivers are loaded, rather than static as provided by the old driver. The infrastructure provided by drivers/phy/phy-core.c seems to fit that purpose ideally. The new driver only supports device tree probing for now.

| | | | | | | | | | | | | | | We index the RX/TX speed select values in the following way: rx_tx_spd[miphy_phy->sata_gen]; However rx_tx_spd[] starts at index zero and the SATA_GENx's start at one. In this patch we pad out the first element in rx_tx_spd[] in an attempt to realign the values.
