This is a patches separated from one sent earlier [1] with just the removal of any hard-coded reg addresses from Dove pinctrl stub. This is a required step for Dove to leave mach-dove, hop into mach-mvebu, and become part of multi_v7. In the meantime, support for new Armada 375/38x was added that also contain patches for pinctrl [2]. The cleanup patches [3] split off from the original patch set take care of pinctrl-related changes for Armada 375/38x. Since this patch set now already depends on Armada 375/38x pinctrl through those cleanup patches, we take care of Armada 375/38x binding updates here, too. For Dove, this patch set removes all hardcoded addresses from pinctrl-dove by either requesting additional resources or a syscon provided regmap for global config registers. As this changes existing driver to DT binding relationship, all additional resources are probed in a backward compatible way. If the corresponding resource cannot be found, we derive it from the existing pinctrl resource and warn about the old DTB firmware. Patches 1-2 add or update binding documentation for dove, global config syscon, and pinctrl-dove. Patch 2 also documents missing reg property requirement for other mvebu pinctrl nodes, including new Armada 375/38x. Patch 3 and 4 add the new pinctrl reg property values and global config register syscon to exisiting dove.dtsi. Patches 5-6 request either additional reg ranges or the syscon regmap in a DT-backward compatible way. If any resource cannot be derived from DT node, we warn about an old DTB firmware. Patches 7-10 finally remove any hardcoded addresses from Dove SoC pinctrl driver and use the iomap/regmap resources instead. DT and binding related patches have also been sent to DT maintainers and corresponding lists, additional pinctrl related patches have been sent to pinctrl/mvebu maintainers and LAKML only. This patch set is based on v3.14-rc1 and depends on some cleanup patches that will go into v3.15. We have a lot of stuff for v3.15 already in mvebu, so I am okay with postponing this and/or the following dove-to- mvebu patches for v3.16. As Jason prepares mvebu pinctrl PRs for LinusW, it is up to him when to take it with LinusW's Acked-by. Nevertheless, there is an *unstable* branch based on v3.14-rc1, with mvebu/pinctrl-3xx and mvebu/pinctrl merged in at (still named -for-3.15) https://github.com/shesselba/linux-dove.git unstable/dove-pinctrl-for-3.15_v1 [1] http://www.spinics.net/lists/arm-kernel/msg303496.html [2] http://www.spinics.net/lists/arm-kernel/msg306409.html [3] http://lkml.org/lkml/2014/2/23/43 Sebastian Hesselbarth (10): devicetree: bindings: add missing Marvell Dove SoC documentation devicetree: bindings: update MVEBU pinctrl binding documentation ARM: dove: add additional pinctrl registers ARM: dove: add global-config register node pinctrl: mvebu: dove: request additional resources pinctrl: mvebu: dove: request syscon regmap for global registers pinctrl: mvebu: dove: use remapped mpp base registers pinctrl: mvebu: dove: use remapped mpp4 register pinctrl: mvebu: dove: use remapped pmu_mpp registers pinctrl: mvebu: dove: use global register regmap .../devicetree/bindings/arm/marvell,dove.txt | 22 ++ .../pinctrl/marvell,armada-370-pinctrl.txt | 1 + .../pinctrl/marvell,armada-375-pinctrl.txt | 1 + .../pinctrl/marvell,armada-38x-pinctrl.txt | 1 + .../bindings/pinctrl/marvell,armada-xp-pinctrl.txt | 1 + .../bindings/pinctrl/marvell,dove-pinctrl.txt | 1 + .../bindings/pinctrl/marvell,kirkwood-pinctrl.txt | 1 + .../bindings/pinctrl/marvell,mvebu-pinctrl.txt | 2 +- arch/arm/boot/dts/dove.dtsi | 10 +- drivers/pinctrl/mvebu/Kconfig | 1 + drivers/pinctrl/mvebu/pinctrl-dove.c | 286 +++++++++++++-------- 11 files changed, 213 insertions(+), 114 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/marvell,dove.txt --- Cc: Rob Herring <robh+dt@xxxxxxxxxx> Cc: Pawel Moll <pawel.moll@xxxxxxx> Cc: Mark Rutland <mark.rutland@xxxxxxx> Cc: Ian Campbell <ijc+devicetree@xxxxxxxxxxxxxx> Cc: Kumar Gala <galak@xxxxxxxxxxxxxx> Cc: Rob Landley <rob@xxxxxxxxxxx> Cc: Linus Walleij <linus.walleij@xxxxxxxxxx> Cc: Russell King <linux@xxxxxxxxxxxxxxxx> Cc: Jason Cooper <jason@xxxxxxxxxxxxxx> Cc: Andrew Lunn <andrew@xxxxxxx> Cc: Gregory Clement <gregory.clement@xxxxxxxxxxxxxxxxxx> Cc: devicetree@xxxxxxxxxxxxxxx Cc: linux-doc@xxxxxxxxxxxxxxx Cc: linux-arm-kernel@xxxxxxxxxxxxxxxxxxx Cc: linux-kernel@xxxxxxxxxxxxxxx -- 1.8.5.3 -- 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
