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 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]

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

https://lore.kernel.org/lkml/20210308195033.GA2855292@robh.at.kernel.org/
- 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@gmail.com/
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@foss.st.com>
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

There are some mirror difference between stm32h743 and stm32h750: Number of A/D Converters (typ): stm32h743(none), stm32h750(3) Crypto: stm32h743(none), stm32h750(HASH-AES, DES/TDES, HMAC, MD5, SHA) you can find detail diff at link: https://www.st.com/en/microcontrollers-microprocessors/stm32h7-series.html#products (select stm32h743xi, stm32h750xb to compare) I have two options for this changes. - rename stm32h743.dtsi to stm32h7.dtsi, add crypto part to stm32h7.dtsi in the future. - make the reference like this (just like stm32f429 <-- stm32f469, stm32mp151 <-- stm32mp153 <-- stm32mp157 did) stm32h743.dtsi <-- stm32h75x.dtsi (stm32h750, stm32h753, stm32h757 all with HW crypto/hash inside) we can add crypto to stm32h75x.dtsi, i will just rename stm32h750.dtsi to stm32h75x.dtsi I'd like to use option-2, which one do you like? thanks. regards.
