From: dillon min <dillon.minfei@xxxxxxxxx> This patchset intend to add art-pi board support, this board developed by rt-thread(https://www.rt-thread.org/). Board resources: 8MiB QSPI flash 16MiB SPI flash 32MiB SDRAM AP6212 wifi,bt,fm comb sw context: - as stm32h750 just has 128k bytes internal flash, so running a fw on internal flash to download u-boot/kernel to qspi flash, boot u-boot/kernel from qspi flash. this fw is based on rt-thread. - kernel can be xip on qspi flash or load to sdram - root filesystem is jffs2(created by buildroot), stored on spi flash to support the boad, add following changes. - fix r0-r3, r12 register restore failed after svc call, - add dts binding - update yaml doc --- changes in v9: - move gpio{a..k} entries from stm32h7-pinctrl.dtsi to stm32h743.dtsi v8 link: https://lore.kernel.org/lkml/1617094704-10040-1-git-send-email-dillon.minfei@xxxxxxxxx/ changes in v8: - drop '[PATCH v7 3/6] ARM: dts: stm32: introduce stm32h7-pinctrl.dtsi to support stm32h750' - stm32h743-pinctrl.dtsi file - move compatible string "st,stm32h743-pinctrl" from stm32h7-pinctrl.dtsi to stm32h743.dtsi - update stm32h743i-{dico/eval}.dtsi to include stm32h7-pinctrl.dtsi - move file stm32h743.dtsi submit position to [PATCH V8 3/6] v7 link: https://lore.kernel.org/lkml/1617071338-9436-1-git-send-email-dillon.minfei@xxxxxxxxx/ changes in v7: - remove changes in Documentation/devicetree/bindings/pinctrl/st,stm32-pinctrl.yaml Hi Rob Herring as you has already ack this patch, please ignore it. thanks history link: https://lore.kernel.org/lkml/1614758717-18223-4-git-send-email-dillon.minfei@xxxxxxxxx/ https://lore.kernel.org/lkml/20210308195033.GA2855292@xxxxxxxxxxxxxxxxxx/ - remove "[PATCH v6 8/9] pinctrl: stm32: Add STM32H750 MCU pinctrl support" remove "[PATCH v6 5/9] ARM: dts: stm32: add stm32h750-pinctrl.dtsi" - reference to stm32h743-pinctrl.dtsi in stm32h750i-art-pi.dts v6 link: https://lore.kernel.org/lkml/1616757302-7889-1-git-send-email-dillon.minfei@xxxxxxxxx/ changes in v6: - add gpiox{gpio-ranges, ngpios} in stm32h7-pinctrl.dtsi - add status="disabled" in stm32h743.dtsi changes in v5: - accroding to rob's suggestion, replace false with 'type: object' of 'additionalProperties'. - add Tested-by: Valentin Caron <valentin.caron@xxxxxxxxxxx> changes in v4: - use unevaluatedProperties: false to fix dtbs_check warrnings instead of add 'bluetooth' in st,stm32-uart.yaml changes in v3: - fix dtbs_check warrning: (8002cbd78fd5 and 4bc21d3dd678) >> arch/arm/boot/dts/stm32h743i-eval.dt.yaml: soc: pin-controller: {'type': 'object'} is not allowed for {'#address-cells': [[1]], '#size-cells': [[1]], 'ranges': [[0, >> arch/arm/boot/dts/stm32h743i-eval.dt.yaml: soc: 'i2c@40005C00', 'i2c@58001C00' do not match any of the regexes: '@(0|[1-9a-f][0-9a-f]*)$', '^[^@]+$', 'pinctrl-[0-9]+' >> arch/arm/boot/dts/stm32h750i-art-pi.dt.yaml: serial@40004800: 'bluetooth' does not match any of the regexes: 'pinctrl-[0-9]+' changes in v2: - reorganize the pinctrl device tree about stm32h7-pinctrl/stm32h743/750-pinctrl stm32h7-pinctrl.dtsi --> stm32h743-pinctrl.dtsi --> stm32h743i-disco.dts | |-> stm32h743i-eval.dts |-> stm32h750-pinctrl.dtsi --> stm32h750i-art-pi.dts same to the stm32f7/f4's pinctrl style - fix author name/copyright mistake - add compatible string st,stm32h750-pinctrl to pinctl-stm32h743.c as they have same pin alternate functions, update Kconfig description - make item in stm32h750i-art-pi.dts sort by letter *** BLURB HERE *** dillon min (6): Documentation: arm: stm32: Add stm32h750 value line doc dt-bindings: arm: stm32: Add compatible strings for ART-PI board ARM: dts: stm32: introduce stm32h7-pinctrl.dtsi to support stm32h750 ARM: dts: stm32: add support for art-pi board based on stm32h750xbh6 ARM: stm32: Add a new SOC - STM32H750 dt-bindings: serial: stm32: Use 'type: object' instead of false for 'additionalProperties' Documentation/arm/index.rst | 1 + Documentation/arm/stm32/stm32h750-overview.rst | 34 +++ .../devicetree/bindings/arm/stm32/stm32.yaml | 4 + .../devicetree/bindings/serial/st,stm32-uart.yaml | 3 +- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/stm32h7-pinctrl.dtsi | 275 ++++++++++++++++++ arch/arm/boot/dts/stm32h743-pinctrl.dtsi | 306 --------------------- arch/arm/boot/dts/stm32h743.dtsi | 176 +++++++++++- arch/arm/boot/dts/stm32h743i-disco.dts | 2 +- arch/arm/boot/dts/stm32h743i-eval.dts | 2 +- arch/arm/boot/dts/stm32h750.dtsi | 6 + arch/arm/boot/dts/stm32h750i-art-pi.dts | 229 +++++++++++++++ arch/arm/mach-stm32/board-dt.c | 1 + 13 files changed, 729 insertions(+), 311 deletions(-) create mode 100644 Documentation/arm/stm32/stm32h750-overview.rst create mode 100644 arch/arm/boot/dts/stm32h7-pinctrl.dtsi delete mode 100644 arch/arm/boot/dts/stm32h743-pinctrl.dtsi create mode 100644 arch/arm/boot/dts/stm32h750.dtsi create mode 100644 arch/arm/boot/dts/stm32h750i-art-pi.dts -- 2.7.4
