From mboxrd@z Thu Jan 1 00:00:00 1970 From: Laurent Pinchart Subject: [PATCH v5 00/22] SH pinctrl DT support Date: Wed, 12 Jun 2013 00:22:29 +0200 Message-ID: <1370989371-30846-1-git-send-email-laurent.pinchart+renesas@ideasonboard.com> Return-path: Sender: linux-sh-owner@vger.kernel.org To: linux-sh@vger.kernel.org Cc: devicetree-discuss@lists.ozlabs.org, linux-arm-kernel@lists.infradead.org, Linus Walleij , Magnus Damm , Guennadi Liakhovetski , James Hogan List-Id: devicetree@vger.kernel.org Hello, Here's the fifth version of the SuperH and SH Mobile pin controllers (PFC) DT support patch set. The patches are based on tags/renesas-next-20130611v2 from Simon's tree (git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git) and the R-Car GPIO DT bindings proposal ("[RFC/PATCH v2 0/2] R-Car GPIO DT bindings"). The result is available in my tree at git://linuxtv.org/pinchartl/fbdev.git pinmux/3.10/dt The series starts with a proposal for generic pinconf DT bindings, already posted as "[RFC] pinctrl: generic: Add DT bindings". The rest is pretty self-explanatory. DT bindings are added in patch 03/22, and the following patches gradually move SoC code and board code over to the device tree for the armadilla800eva-reference, kzm9g-reference and marzen-reference boards. The code has been tested on the three boards, but armadillo800eva has received less testing as it can't be booted all the way to userspace with network support due to missing DT bindings. Comments will be very appreciated on the DT bindings (01/22 and 03/22). Points I'm a bit unsure about include: - Should the driver support pin configuration subnodes as currently implemented, or should the subnodes be promoted to regular pin configuration nodes, with clients referencing multiple nodes ? - Should the driver allow mixing function and configuration properties in a pin configuration node as currently implemented, or should it restrict the pin configuration nodes to either a function or one (or more) configuration(s) ? I'd like to get this series in v3.11. Linus, do you think that would be possible ? If the generic pinconf DT bindings can't make it in time I can respin the patches with pinconf support removed, and add it back along with the generic pinconf DT bindings for v3.12. Changes since v4: - Added generic pinconf bindings - Use symbolic names for GPIO flags Changes since v3: - Fixed the GPIO flags description in the DT bindings documentation - Mention the gpio-rcar driver in the DT bindings documentation for platforms that use it - Removed unneeded #ifdef CONFIG_OF...#endif - Removed unused support for platform data - Simplified error path in sh_pfc_dt_node_to_map() - Added gpio-ranges for r8a7778, r8a7779 and r8a7790 Changes since v2: - Added pin configuration properties - Rewrote all arch changes Changes since v1: - Fixed gpio cell number 2 documentation - Added missing gpio-controller and #gpio-cells properties to r8a7740 DT - Split kzm9g DT patch into SoC and board patches - Dropped pinctrl mappings move to DT Laurent Pinchart (22): pinctrl: generic: Add DT bindings sh-pfc: Remove support for platform data sh-pfc: Add DT support ARM: shmobile: r8a73a4: Add pin control device to device tree ARM: shmobile: r8a7740: Add pin control device to device tree ARM: shmobile: r8a7778: Add pin control device to device tree ARM: shmobile: r8a7778: Add GPIO controller devices to device tree ARM: shmobile: r8a7779: Add pin control device to device tree ARM: shmobile: r8a7779: Add GPIO controller devices to device tree ARM: shmobile: r8a7790: Add pin control device to device tree ARM: shmobile: r8a7790: Add GPIO controller devices to device tree ARM: shmobile: sh7372: Add pin control device to device tree ARM: shmobile: sh73a0: Add pin control device to device tree ARM: shmobile: armadillo-reference: Move pinctrl mappings to device tree ARM: shmobile: armadillo-reference: Add st1232 pin mappings ARM: shmobile: armadillo-reference: Move st1232 reset GPIO to DT ARM: shmobile: armadillo-reference: Add LED1-LED4 to the device tree ARM: shmobile: kzm9g-reference: Move pinctrl mappings to device tree ARM: shmobile: kzm9g-reference: Move SDHI regulators to DT ARM: shmobile: kzm9g-reference: Add LED1-LED4 to the device tree ARM: shmobile: marzen-reference: Move pinctrl mappings to device tree ARM: shmobile: marzen-reference: Add LED2-LED4 to the device tree .../bindings/pinctrl/pinctrl-bindings.txt | 29 +++ .../bindings/pinctrl/renesas,pfc-pinctrl.txt | 156 ++++++++++++++++ arch/arm/boot/dts/r8a73a4.dtsi | 7 + .../boot/dts/r8a7740-armadillo800eva-reference.dts | 34 ++++ arch/arm/boot/dts/r8a7740.dtsi | 8 + arch/arm/boot/dts/r8a7778.dtsi | 56 ++++++ arch/arm/boot/dts/r8a7779-marzen-reference.dts | 49 +++++ arch/arm/boot/dts/r8a7779.dtsi | 76 ++++++++ arch/arm/boot/dts/r8a7790.dtsi | 66 +++++++ arch/arm/boot/dts/sh7372.dtsi | 8 + arch/arm/boot/dts/sh73a0-kzm9g-reference.dts | 90 +++++++++- arch/arm/boot/dts/sh73a0.dtsi | 8 + .../board-armadillo800eva-reference.c | 18 +- arch/arm/mach-shmobile/board-kzm9g-reference.c | 47 ----- arch/arm/mach-shmobile/board-marzen-reference.c | 28 --- drivers/pinctrl/pinconf-generic.c | 94 ++++++++++ drivers/pinctrl/pinconf.h | 17 ++ drivers/pinctrl/sh-pfc/core.c | 65 ++++++- drivers/pinctrl/sh-pfc/pinctrl.c | 199 +++++++++++++++++++++ 19 files changed, 959 insertions(+), 96 deletions(-) create mode 100644 Documentation/devicetree/bindings/pinctrl/renesas,pfc-pinctrl.txt -- Regards, Laurent Pinchart
