From: dillon min <[email protected]>
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 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 <[email protected]>
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/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

This patch adds STM32H750 pinctrl and GPIO support
since stm32h750 has the same pin alternate functions
with stm32h743, so just reuse the stm32h743's pinctrl
driver

From: dillon min <[email protected]>
To use additional properties 'bluetooth' on serial, need replace false with
'type: object' for 'additionalProperties' to make it as a node, else will
run into dtbs_check warnings.
'arch/arm/boot/dts/stm32h750i-art-pi.dt.yaml: serial@40004800:
'bluetooth' does not match any of the regexes: 'pinctrl-[0-9]+'
Fixes: af1c2d81695b ("dt-bindings: serial: Convert STM32 UART to json-schema")
Reported-by: kernel test robot <[email protected]>
