The RCU (Reset controller Unit) register block provides many different functionalities. Before they were handed by the code in arch/mips/lantiq /xway/reset.c, now there are separate drivers for the functionality. This block provides support for reset controller, GPHY firmware loading, USB PHY initialization and cross bar configuration. These changes are making the old device tree incompatible with the current kernel. The upstream Linux kernel supports loading the device tree blob from the boot loader since about one year, the latest released vendor kernel does not support loading the device tree from a bot loader. I would prefer if this would go through the mips tree. There are more patches planed which would convert the Lantiq code to the common clock framework. This is based on patches from Martin Blumenstingl and is a preparation to convert the Lantiq target to the common clock framework which was also started by Martin Blumenstingl. Changelog: v2: * remove the rcu_ prefix for device names in device tree * add both clocks to the gphy driver documentation * use 2 cells for the reset controller, one for the status bit and one for the set bit, they are different for some reset bits. reset-status and reset-request attribute were removed then. * remove the documentation of the not existing sub nodes of the usb phy * remove manual gpio vbus handling in the usb phy driver and use the generic phy regulator now. * do not check if the usb phy reset is not null, the reset framework does this. * do not print an error message when -EPROBE_DEFER was returned Hauke Mehrtens (7): mtd: lantiq-flash: drop check of boot select mtd: spi-falcon: drop check of boot select watchdog: lantiq: access boot cause register through regmap MIPS: lantiq: remove ltq_reset_cause() and ltq_boot_select() MIPS: lantiq: remove old reset controller implementation MIPS: lantiq: remove old GPHY loader code MIPS: lantiq: remove old USB PHY initialisation Martin Blumenstingl (8): MIPS: lantiq: Use of_platform_populate instead of __dt_register_buses MIPS: lantiq: Enable MFD_SYSCON to be able to use it for the RCU MFD Documentation: DT: MIPS: lantiq: Add docs for the RCU bindings MIPS: lantiq: Convert the xbar driver to a platform_driver reset: Add a reset controller driver for the Lantiq XWAY based SoCs MIPS: lantiq: Add a GPHY driver which uses the RCU syscon-mfd phy: Add an USB PHY driver for the Lantiq SoCs using the RCU module MIPS: lantiq: Remove the arch/mips/lantiq/xway/reset.c implementation .../devicetree/bindings/mips/lantiq/rcu-gphy.txt | 38 ++ .../devicetree/bindings/mips/lantiq/rcu.txt | 84 +++++ .../devicetree/bindings/mips/lantiq/xbar.txt | 24 ++ .../bindings/phy/phy-lantiq-rcu-usb2.txt | 41 +++ .../devicetree/bindings/reset/lantiq,rcu-reset.txt | 30 ++ MAINTAINERS | 1 + arch/mips/include/asm/mach-lantiq/lantiq.h | 4 - arch/mips/lantiq/Kconfig | 2 + arch/mips/lantiq/falcon/reset.c | 22 -- arch/mips/lantiq/prom.c | 3 +- arch/mips/lantiq/xway/Makefile | 4 +- arch/mips/lantiq/xway/reset.c | 387 --------------------- arch/mips/lantiq/xway/sysctrl.c | 69 +--- arch/mips/lantiq/xway/xrx200_phy_fw.c | 113 ------ drivers/mtd/maps/lantiq-flash.c | 6 - drivers/phy/Kconfig | 8 + drivers/phy/Makefile | 1 + drivers/phy/phy-lantiq-rcu-usb2.c | 275 +++++++++++++++ drivers/reset/Kconfig | 6 + drivers/reset/Makefile | 1 + drivers/reset/reset-lantiq-rcu.c | 201 +++++++++++ drivers/soc/Makefile | 1 + drivers/soc/lantiq/Makefile | 2 + drivers/soc/lantiq/gphy.c | 243 +++++++++++++ drivers/soc/lantiq/xbar.c | 101 ++++++ drivers/spi/spi-falcon.c | 5 - drivers/watchdog/lantiq_wdt.c | 48 ++- include/dt-bindings/mips/lantiq_rcu_gphy.h | 15 + 28 files changed, 1135 insertions(+), 600 deletions(-) create mode 100644 Documentation/devicetree/bindings/mips/lantiq/rcu-gphy.txt create mode 100644 Documentation/devicetree/bindings/mips/lantiq/rcu.txt create mode 100644 Documentation/devicetree/bindings/mips/lantiq/xbar.txt create mode 100644 Documentation/devicetree/bindings/phy/phy-lantiq-rcu-usb2.txt create mode 100644 Documentation/devicetree/bindings/reset/lantiq,rcu-reset.txt delete mode 100644 arch/mips/lantiq/xway/reset.c delete mode 100644 arch/mips/lantiq/xway/xrx200_phy_fw.c create mode 100644 drivers/phy/phy-lantiq-rcu-usb2.c create mode 100644 drivers/reset/reset-lantiq-rcu.c create mode 100644 drivers/soc/lantiq/Makefile create mode 100644 drivers/soc/lantiq/gphy.c create mode 100644 drivers/soc/lantiq/xbar.c create mode 100644 include/dt-bindings/mips/lantiq_rcu_gphy.h -- 2.11.0 -- 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
