Hi, This is the fourth version of the patchset adding the new Exynos USB 2.0 PHY driver. The driver uses the Generic PHY Framework. A month has passed since the last version. I have addressed numerous comments that appeared on the mailing list in this patch. I would like to specially thank Kishon, Tomasz, Matt and Vivek for their comments. This patch contains two necessary patches to the phy core. It is very useful to be able to get phy using a device tree node. In addition this patch depends on: [PATCH V11 1/3] ARM: dts: Add pmu sysreg node to exynos5250 and exynos5420 dtsi files [1]. Best wishes, Kamil Debski [1] - http://www.spinics.net/lists/linux-samsung-soc/msg24528.html ---------------- Changes from v3: - using PMU and system registers indirectly via syscon - change labelling - change Kconfig name - fixed typos/stray whitespace - move of_phy_provider_register() to the end of probe - add a regular error return code to the rate_to_clk functions - cleanup code and remove unused code - change struct names to avoid collisions - add mechanism to support multiple phys by the ehci driver ---------------- Changes from v2: - rebase all patches to the usb-next branch - fixes in the documentation file - remove wrong entries in the phy node (ranges, and #address- & #size-cells) - add clocks and clock-names as required properites - rephrase a few sentences - fixes in the ehci-exynos.c file - move phy_name variable next to phy in exynos_ehci_hcd - remove otg from exynos_ehci_hcd as it was no longer used - move devm_phy_get after the Exynos5440 skip_phy check - fixes in the s3c-hsotg.c file - cosmetic fixes (remove empty line that was wrongfully added) - fixes in the main driver - remove cpu_type in favour for a boolean flag matched with the compatible value - rename files, structures, variables and Kconfig entires - change from simple "uphy" to "usb2_phy" - fix multiline comments style - simplify #ifdefs in of_device_id - fix Kconfig description - change dev_info to dev_dbg where reasonable - cosmetic changes (remove wrongful blank lines) - remove unnecessary reference counting ---------------- Changes from v1: - the changes include minor fixes of the hardware initialization of the PHY module - some other minor fixes were introduced ---------------------- Original cover letter: Hi, This patch adds a new drive for USB PHYs for Samsung SoCs. The driver is using the Generic PHY Framework created by Kishon Vijay Abrahan I. It can be found here https://lkml.org/lkml/2013/8/21/29. This patch adds support to Exynos4 family of SoCs. Support for Exynos3 and Exynos5 is planned to be added in the near future. I welcome your comments. ---------------------- [1] https://lkml.org/lkml/2013/8/21/29 Kamil Debski (8): phy: core: Change the way of_phy_get is called phy: core: Add devm_of_phy_get to phy-core phy: Add new Exynos USB PHY driver usb: ehci-s5p: Change to use phy provided by the generic phy framework usb: s3c-hsotg: Use the new Exynos USB phy driver with the generic phy framework phy: Add Exynos 5250 support to the Exynos USB 2.0 PHY driver dts: Add usb2phy to Exynos 4 dts: Add usb2phy to Exynos 5250 Mateusz Krawczuk (1): phy: Add support for S5PV210 to the Exynos USB PHY driver .../devicetree/bindings/arm/samsung/pmu.txt | 2 + .../devicetree/bindings/phy/samsung-usbphy.txt | 56 +++ .../devicetree/bindings/usb/samsung-hsotg.txt | 4 + Documentation/devicetree/bindings/usb/usb-ehci.txt | 35 ++ arch/arm/boot/dts/exynos4.dtsi | 31 ++ arch/arm/boot/dts/exynos4210.dtsi | 17 + arch/arm/boot/dts/exynos4x12.dtsi | 17 + arch/arm/boot/dts/exynos5250.dtsi | 33 +- drivers/phy/Kconfig | 35 ++ drivers/phy/Makefile | 5 + drivers/phy/phy-core.c | 43 ++- drivers/phy/phy-exynos4210-usb2.c | 264 ++++++++++++++ drivers/phy/phy-exynos4212-usb2.c | 312 +++++++++++++++++ drivers/phy/phy-exynos5250-usb2.c | 363 ++++++++++++++++++++ drivers/phy/phy-s5pv210-usb2.c | 206 +++++++++++ drivers/phy/phy-samsung-usb2.c | 240 +++++++++++++ drivers/phy/phy-samsung-usb2.h | 74 ++++ drivers/usb/gadget/s3c-hsotg.c | 11 +- drivers/usb/host/ehci-exynos.c | 95 +++-- include/linux/phy/phy.h | 3 + 20 files changed, 1789 insertions(+), 57 deletions(-) create mode 100644 Documentation/devicetree/bindings/phy/samsung-usbphy.txt create mode 100644 drivers/phy/phy-exynos4210-usb2.c create mode 100644 drivers/phy/phy-exynos4212-usb2.c create mode 100644 drivers/phy/phy-exynos5250-usb2.c create mode 100644 drivers/phy/phy-s5pv210-usb2.c create mode 100644 drivers/phy/phy-samsung-usb2.c create mode 100644 drivers/phy/phy-samsung-usb2.h -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
