Device driver is follow up version on what Andrea posted in April [1]. It is based on sources from here [2]. I just made few cosmetic changes and addressed review comments from earlier submission. I don't have documentation for this controller. Patch 4 wire up power button on RPi5. Patch 5 adds WiFi Devicetree node for RPi5. Patch 6 adds Bluetooth Devicetree node for RPi5. All this have been tested as kernel was directly booted RPi5 via kernel= config.txt option and cmdline.txt file with following content (Note I am using Tumbleweed RPi raw images) # cat /boot/efi/cmdline.txt root=/dev/mmcblk0p3 rootwait rw systemd.show_status=1 console=tty ignore_loglevel earlycon console=ttyAMA10,115200 With all these patches Bluetooth and Wifi are working fine (tm) with firmware files provided by openSUSE Tumbleweed. All comments and suggestions are welcome! Happy hacking!

Renaming the macro name and the macro parameters to better reflect the semantic. - reworked MUX_BIT() macro to be more streamlined and easy to understand. - added PAD_BIT() macro to avoid code duplication. - renamed 'lock' variable to 'fsel_lock'. - added some comments about non-existent pins on D0 silicon revision pin declarations. - brcmstb_pinctrl_fsel_set(), brcmstb_pull_config_set() and brcmstb_pinconf_set() (and functions that call them) can now return -EINVAL as error. - added myself as MODULE_AUTHOR. - dropped the 'brcm,bcm2712-[aon-]pinctrl' fallback compatible. Only c0 or d0 compatibles are permitted now. --- DTS --- - moved 'clock-frequency' property from (uarta) board dts node to SoC dtsi node. - added 'brcm,sdhci-brcmstb' compatible and 'clock-names' property to mmc node to avoid dt_binding_check errors. - added 'brcm,bcm7445-gpio' compatible to gpio node to avoid dt_binding_check errors. - renamed all pinctrl pin nodes as per yaml schema (*-state and *-pins). - changed 'brcm,bcm2712-*pinctrl' to 'brcm,bcm2712c0-*pinctrl' since the former was more of a fallback and does not reflect a real silicon revision. - moved status="okay" to the last entry in 'uarta' node. - removed 'local-*-address' property from everywhere. - dropped 'skip-init' property in 'uarta' node since it does not apply to linux kernel. - renamed 'pwr-button' node to 'gpio-keys' and 'pwr_key' node to 'power_button'. - dropped an userspace related 'brcm,gpio-direct' property from gpio node. --- DT BINDINGS --- - binding schema file renamed to 'brcm,bcm2712c0-pinctrl.yaml' to reflect the compatible name. - dropped the 'brcm,bcm2712-[aon-]pinctrl' fallback compatible. Only c0 or d0 compatibles are permitted now. - added example section. - moved allOf: block at the beginning of the schema. - dropped some unnecessary new lines. - replaced current layout to describe the pin subnodes with patternProperties (nodes now end with -state and -pins). - expanded the schema description to give some context about STB family of pin controller and added some details about C0 and D0 silicon variants. This is also reflected in the commit message. --- MISC --- - enabled CONFIG_PINCTRL_BRCMSTB in arm64 defconfig.

Ivanov" <iivanov@suse.de> The STB pin controller represents a family whose silicon instances are found e.g. on BCM2712 SoC. In particular, on RaspberryPi 5, there are two separate instantiations of the same IP block which differ in the number of pins that are associated and the pinmux functions for each of those pins. The -aon- variant stands for 'Always On'. Depending on the revision of the BCM2712 (CO or D0), the pin controller instance has slight differences in the register layout. Signed-off-by: Ivan T.

Anyway, I'm preparing a new revision (which will be V3) after amending it after Rob's automated script warning. I'll also split the patchset into two, oen with binding / driver for SoC pin controller and another with thie remaining DTS related patches.

* [PATCH 0/7] Add pin control driver for BCM2712 SoC @ 2024-07-31 6:28 Ivan T. Ivanov 2024-07-31 14:25 ` Rob Herring (Arm) 0 siblings, 1 reply; 14+ messages in thread From: Ivan T.

Ivanov Hi, The following patches add a pin control driver for the BCM2712 SoC and few pin/gpio Devicetree nodes for Raspberry Pi 5. Device driver is follow up version on what Andrea posted in April [1]. It is based on sources from here [2]. I just made few cosmetic changes and addressed review comments from earlier submission. I don't have documentation for this controller. Patch 3 was already posted by Andrea and it is in Broadcom integration tree[3]. Unfortunately it is still not in the Linus tree[4]. So I added it here as base for my changes and to easy building and testing. Patch 5 wire up power button on RPi5 Patch 6 adds WiFi Devicetree node for RPi5 Patch 7 adds Bluetooth Devicetree node for RPi5 They are few complaints from checkpatch.pl. Like few lines over 100 columns, which I keep that way for better readability or usage of EOPNOTSUPP, but it is according pin control API document. All this have been tested as kernel was directly booted RPi5 via kernel= config.txt option and cmdline.txt file with following content (Note I am using Tumbleweed RPi raw images) # cat /boot/efi/cmdline.txt root=/dev/mmcblk0p3 rootwait rw systemd.show_status=1 console=tty ignore_loglevel earlycon console=ttyAMA10,115200 With all these patches Bluetooth and Wifi are working fine (tm) with firmware files provided by openSUSE Tumbleweed. All comments and suggestions are welcome! Happy hacking!

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not.
