Message-ID: <1369412476-14245-1-git-send-email-james.hogan@imgtec.com> Date: Fri, 24 May 2013 17:21:07 +0100 From: James Hogan <james.hogan@...tec.com> To: <linux-kernel@...r.kernel.org> CC: James Hogan <james.hogan@...tec.com>, Arnd Bergmann <arnd@...db.de>, "Grant Likely" <grant.likely@...retlab.ca>, Linus Walleij <linus.walleij@...aro.org>, Rob Herring <rob.herring@...xeda.com>, Rob Landley <rob@...dley.net>, Thomas Gleixner <tglx@...utronix.de>, <devicetree-discuss@...ts.ozlabs.org>, <linux-doc@...r.kernel.org> Subject: [PATCH v2 0/9] Add some TZ1090 SoC infrastructure The Toumaz Xenif TZ1090 SoC (AKA Comet) contains a 2-threaded Linux-capable HTP (Meta 2), and is found in a number of development boards and digital radios, such as the Minimorph Development Platform. This patchset adds some core infrastructure for the TZ1090, including drivers for the powerdown controller (PDC) irqchip, general/PDC pin controllers, and general/PDC GPIO controllers. It's not yet enough to get the UARTs going (no common clock framework) so JTAG/QEMU with DA TTY is still needed to get a shell. A QEMU with a Meta frontend and some TZ1090 emulation, and the SoC Technical Reference Manual which documents the registers used by both GPIO drivers and both pin control drivers can be downloaded from the Minimorph SDK (registration of a Minimorph is currently required): http://imgtec.com/meta_insider/metaflow-sdk.asp Changes in v2: There've been plenty of changes since v1 (thanks for all the feedback!) so I think it's time for v2. I believe the only feedback not yet addressed is changing irq-imgpdc driver to use generic irqchip. - rebased on v3.10-rc2 - removed arch/metag/soc/ directory - removed arch/metag/include/asm/soc-tz1090/gpio.h - irq-imgpdc: use cached versions of irq_en and irq_route registers - irq-imgpdc: switch to using raw_spinlock - irq-imgpdc: (not had time to switch to generic irqchip yet) - add drive strength to generic pinconf debugfs output (patch 4) - add BIAS_BUS_HOLD generic pinconf (patch 5) - pinctrl-tz1090: switched to generic pinconf (a previous patch adds the BIAS_BUS_HOLD generic pinconf) - pinctrl-tz1090: changed device tree bindings to more closely match generic pinconf (separate tristate, pull-up, pull-down, bus-hold flags instead of pull=<X>, drive-strength measured in mA) - pinctrl-tz1090: removed "select" pinconf. Instead pins in a pin group have their own individual pin groups and can be individually muxed. Different pins in same pin mux group muxed to different functions is disallowed. Pin switched to peripheral mode when mux enabled. - pinctrl-tz1090: make use of BIT() from linux/bitops.h - pinctrl-tz1090: add a whole bunch of comments - gpio-tz1090: remove references to Linux flags in dt bindings - gpio-tz1090: make use of BIT() from linux/bitops.h - gpio-tz1090: make register accessors inline to match pinctrl - gpio-tz1090: update gpio-ranges to use 3 cells after recent ABI breakage - pinctrl-tz1090-pdc: switched to generic pinconf (a previous patch adds the BIAS_BUS_HOLD generic pinconf) - pinctrl-tz1090-pdc: changed device tree bindings to more closely match generic pinconf (separate tristate, pull-up, pull-down, bus-hold flags instead of pull=<X>, drive-strength measured in mA) - pinctrl-tz1090-pdc: make use of BIT() from linux/bitops.h - pinctrl-tz1090-pdc: add a whole bunch of comments - gpio-tz1090-pdc: remove references to Linux flags in dt bindings - gpio-tz1090-pdc: make use of BIT() from linux/bitops.h - gpio-tz1090-pdc: make register accessors inline to match pinctrl - gpio-tz1090-pdc: update gpio-ranges to use 3 cells after recent ABI breakage Cc: Arnd Bergmann <arnd@...db.de> Cc: Grant Likely <grant.likely@...retlab.ca> Cc: Linus Walleij <linus.walleij@...aro.org> Cc: Rob Herring <rob.herring@...xeda.com> Cc: Rob Landley <rob@...dley.net> Cc: Thomas Gleixner <tglx@...utronix.de> Cc: devicetree-discuss@...ts.ozlabs.org Cc: linux-doc@...r.kernel.org James Hogan (9): metag: of_platform_populate from arch generic code metag: minimal TZ1090 (Comet) SoC infrastructure irq-imgpdc: add ImgTec PDC irqchip driver pinconf-generic: add drive strength to debugfs output pinconf-generic: add BIAS_BUS_HOLD pinconf pinctrl-tz1090: add TZ1090 pinctrl driver gpio-tz1090: add TZ1090 gpio driver pinctrl-tz1090-pdc: add TZ1090 PDC pinctrl driver gpio-tz1090-pdc: add TZ1090 PDC gpio driver .../devicetree/bindings/gpio/gpio-tz1090-pdc.txt | 41 + .../devicetree/bindings/gpio/gpio-tz1090.txt | 83 + .../devicetree/bindings/metag/pdc-intc.txt | 112 + .../bindings/pinctrl/img,tz1090-pdc-pinctrl.txt | 128 ++ .../bindings/pinctrl/img,tz1090-pinctrl.txt | 223 ++ .../devicetree/bindings/vendor-prefixes.txt | 1 + arch/metag/Kconfig.soc | 14 + arch/metag/Makefile | 2 +- arch/metag/boot/dts/Makefile | 2 + arch/metag/boot/dts/tz1090.dtsi | 106 + arch/metag/boot/dts/tz1090_generic.dts | 10 + arch/metag/configs/tz1090_defconfig | 42 + arch/metag/kernel/setup.c | 4 + drivers/gpio/Kconfig | 14 + drivers/gpio/Makefile | 2 + drivers/gpio/gpio-tz1090-pdc.c | 242 +++ drivers/gpio/gpio-tz1090.c | 629 ++++++ drivers/irqchip/Kconfig | 4 + drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-imgpdc.c | 541 +++++ drivers/pinctrl/Kconfig | 12 + drivers/pinctrl/Makefile | 2 + drivers/pinctrl/pinconf-generic.c | 2 + drivers/pinctrl/pinctrl-tz1090-pdc.c | 1105 ++++++++++ drivers/pinctrl/pinctrl-tz1090.c | 2150 ++++++++++++++++++++ include/linux/pinctrl/pinconf-generic.h | 6 + 26 files changed, 5477 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/gpio/gpio-tz1090-pdc.txt create mode 100644 Documentation/devicetree/bindings/gpio/gpio-tz1090.txt create mode 100644 Documentation/devicetree/bindings/metag/pdc-intc.txt create mode 100644 Documentation/devicetree/bindings/pinctrl/img,tz1090-pdc-pinctrl.txt create mode 100644 Documentation/devicetree/bindings/pinctrl/img,tz1090-pinctrl.txt create mode 100644 arch/metag/boot/dts/tz1090.dtsi create mode 100644 arch/metag/boot/dts/tz1090_generic.dts create mode 100644 arch/metag/configs/tz1090_defconfig create mode 100644 drivers/gpio/gpio-tz1090-pdc.c create mode 100644 drivers/gpio/gpio-tz1090.c create mode 100644 drivers/irqchip/irq-imgpdc.c create mode 100644 drivers/pinctrl/pinctrl-tz1090-pdc.c create mode 100644 drivers/pinctrl/pinctrl-tz1090.c -- 1.8.1.2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
