Hi all, This series adds support for wakeup capable GPIOs. It is based on Thierry's hiearchical GPIO domains. This approach is based on Stephen's idea [1]. The SoC that is used for this development is a QCOM SDM845. The current patchset is rebased on top of 5.0 and adds documentation for the wakeup-parent and irqdomain-map DT properties along with the the optional irqdomain-map-mask and irqdomain-map-pass-thru properties. Also incorporating comments from Marc on the earlier submission [2]. I cleaned up some of the change history in these patches to match the version number with that of the submission. The dtsi patches are based on Bjorn's changes for increased address and cell size [3] and [4]. Kindly review the series. Thanks, Lina [1]. https://lkml.org/lkml/2018/12/19/813 [2]. https://lkml.org/lkml/2019/2/22/716 [3]. https://patchwork.kernel.org/patch/10767511/ [4]. https://lkml.kernel.org/r/20190117042940.25487-2-bjorn.andersson@xxxxxxxxxx Lina Iyer (8): irqdomain: add bus token DOMAIN_BUS_WAKEUP of/irq: document properties for wakeup interrupt parent drivers: irqchip: add PDC irqdomain for wakeup capable GPIOs dt-bindings: sdm845-pinctrl: add wakeup interrupt parent for GPIO drivers: pinctrl: msm: setup GPIO irqchip hierarchy arm64: dts: qcom: add PDC interrupt controller for SDM845 arm64: dts: qcom: setup PDC as wakeup parent for GPIOs for SDM845 arm64: defconfig: enable PDC interrupt controller for Qualcomm SDM845 Stephen Boyd (1): of: irq: add helper to remap interrupts to another irqdomain Thierry Reding (1): gpio: Add support for hierarchical IRQ domains .../interrupt-controller/interrupts.txt | 39 +++++ .../bindings/pinctrl/qcom,sdm845-pinctrl.txt | 7 +- arch/arm64/boot/dts/qcom/sdm845.dtsi | 87 ++++++++++ arch/arm64/configs/defconfig | 1 + drivers/gpio/gpiolib.c | 15 +- drivers/irqchip/qcom-pdc.c | 72 ++++++++- drivers/of/irq.c | 125 +++++++++++++++ drivers/pinctrl/qcom/pinctrl-msm.c | 151 +++++++++++++++--- include/linux/gpio/driver.h | 6 + include/linux/irqdomain.h | 1 + include/linux/of_irq.h | 1 + include/linux/soc/qcom/irq.h | 23 +++ 12 files changed, 497 insertions(+), 31 deletions(-) create mode 100644 include/linux/soc/qcom/irq.h -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project
