* phy: miphy365x: Pass sysconfig register offsets via syscfg dt property.Peter Griffin2015-01-30
| | | | | | | | | | | | | | | | | | | | | 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: exynos-video-mipi: Fix regression by adding support for PMU regmapSylwester Nawrocki2015-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the Exynos Power Management Unit (PMU) driver was converted to the platform device driver in commit 14fc8b93d47323561edf5d482 ("ARM: EXYNOS: Add platform driver support for Exynos PMU") and then PMU device nodes added to Exynos4 DTs in commit 7b9613aca42a5522d269 ("ARM: dts: add PMU syscon node for exynos4") the mipi video phy driver started failing probing, due to overlapping memory mapped register region resources. Now all the Exynos peripheral devices which have registers in the PMU region are supposed to use the regmap provided by the syscon driver. So support for regmap is added in this patch, this unfortunately creates yet another indirection into that supposedly trivial driver. The additional mutex is required because single register is used by PHY pairs (they share bit in a register). An improvement here could be to allow a PHY instance be created with a driver custom mutex, which would then be common for each PHY pair. This would eliminate one of 3 mutexes which need to be taken in the phy_power_on/ phy_power_off code path. However, I tried to keep this bug fix patch possibly simple. This change is needed to make MIPI DSI displays and MIPI CSI-2 camera sensors working again on Exynos4 boards.

* phy: phy-stih407-usb: Pass sysconfig register offsets via syscfg property.Peter Griffin2015-01-21
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the DP_PHY_ENABLE register is mapped in the driver, and accessed to control power to the PHY. With mfd-syscon and regmap interface available at our disposal, it's wise to use that instead of using a 'reg' property for the controller and allocating a memory resource for that. To facilitate this, we have added another compatible string for Exynso5420 SoC to acquire driver data which contains different DP-PHY-CONTROL register offset.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | Commit ba0d7ed391b7b "ARM: dts: enable ahci sata and sata phy for exynos5250" added a new binding document for the sata phy device, and changed the sata controller binding. However, in both cases significant aspects of the binding remained undocumented. This attempts to reconstruct the actual binding from the usage.

Besides this there are also some other phy related bits which need poking, which are per phy, but shared between the ohci and ehci controllers, so these are also controlled from this new phy driver.
