Hi, The series adds reset controller support for SAMA7G5 SoCs. 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 2/9) and adapt reset controller nodes in device tree files to comply with DT specifications (patch 1/9). Thank you, Claudiu Beznea Changes in v5: - in patch 6/9 added device_reset_min_id, device_reset_max_id to struct at91_reset_data; these will be used in at91_reset_of_xlate() (patch 7/9) allowing expansion of device reset code for future devices; with this member of type const struct at91_reset_data * has been added to struct at91_reset and at91_rcdev_init() gets now only 2 arguments. - in patch 8/9 use filled .device_reset_min_id, .device_reset_max_id - in patch 6/9 use device_get_match_data() - collected tags Changes in v4: - removed patch 10/10 from v3 as it has been taken though at91 tree 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 (9): 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 .../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 + drivers/power/reset/at91-reset.c | 184 ++++++++++++++++-- include/dt-bindings/reset/sama7g5-reset.h | 10 + 16 files changed, 265 insertions(+), 41 deletions(-) create mode 100644 Documentation/devicetree/bindings/reset/atmel,at91sam9260-reset.yaml create mode 100644 include/dt-bindings/reset/sama7g5-reset.h -- 2.34.1
