Compared with previous version the reset controller embedded on SAMA7G5 is able to reset individual on SoC devices (e.g. USB PHY controllers). Among with this I took the change and converted reset controller bindings to YAML (patch 2/8) and adapt reset controller nodes in device tree files to comply with DT specifications (patch 1/8). Thank you, Claudiu Beznea Changes in v3: - use spin_lock_irqsave()/spin_unlock_irqrestore() and lock only on update path - collected tags Changes in v2: - added patches 5/10 and 10/10 - in patch 2/10 use my microchip email address - in patch 4/10 added "SAMA7G5_" in front of macros to cope with file naming and used (GPL-2.0-only OR BSD-2-Clause) - in patch 6/10 documented the structure's members - in patch 7/10: - protect access to reset->dev_base with spin lock - check for valid values of reset_spec->args[0] in at91_reset_of_xlate() - s/if (IS_ERR(reset->rstc_base))/if (IS_ERR(reset->dev_base)) - include dt-bindings/reset/sama7g5-reset.h - document new added structure's members - collected tags Claudiu Beznea (10): ARM: dts: at91: use generic name for reset controller dt-bindings: reset: convert Atmel/Microchip reset controller to YAML dt-bindings: reset: atmel,at91sam9260-reset: add sama7g5 bindings dt-bindings: reset: add sama7g5 definitions power: reset: at91-reset: document structures and enums power: reset: at91-reset: add at91_reset_data power: reset: at91-reset: add reset_controller_dev support power: reset: at91-reset: add support for SAMA7G5 ARM: dts: at91: sama7g5: add reset-controller node ARM: configs: sama7: enable CONFIG_RESET_CONTROLLER .../devicetree/bindings/arm/atmel-sysregs.txt | 15 -- .../reset/atmel,at91sam9260-reset.yaml | 68 +++++++ arch/arm/boot/dts/at91sam9260.dtsi | 2 +- arch/arm/boot/dts/at91sam9261.dtsi | 2 +- arch/arm/boot/dts/at91sam9263.dtsi | 2 +- arch/arm/boot/dts/at91sam9g45.dtsi | 2 +- arch/arm/boot/dts/at91sam9n12.dtsi | 2 +- arch/arm/boot/dts/at91sam9rl.dtsi | 2 +- arch/arm/boot/dts/at91sam9x5.dtsi | 2 +- arch/arm/boot/dts/sam9x60.dtsi | 2 +- arch/arm/boot/dts/sama5d2.dtsi | 2 +- arch/arm/boot/dts/sama5d3.dtsi | 2 +- arch/arm/boot/dts/sama5d4.dtsi | 2 +- arch/arm/boot/dts/sama7g5.dtsi | 7 + arch/arm/configs/sama7_defconfig | 1 + drivers/power/reset/at91-reset.c | 173 ++++++++++++++++-- include/dt-bindings/reset/sama7g5-reset.h | 10 + 17 files changed, 257 insertions(+), 39 deletions(-) create mode 100644 Documentation/devicetree/bindings/reset/atmel,at91sam9260-reset.yaml create mode 100644 include/dt-bindings/reset/sama7g5-reset.h
