pci: brcmstb: Adapt to AXI bridge

2026-06-04T09:50:04Z

Fix-ups for the BCM root complex when it is located behind an AXI bridge and clocked with 54MHz. Some are from kernel commit 377bced88c326, some where picked by Oleksii off a now-stale older branch. All reworked for the simpler setup code in U-Boot. Signed-off-by: Torsten Duwe Co-authored-by: Oleksii Moisieiev Tested-by: Pedro Falcato Reviewed-by: Neil Armstrong

pci: brcmstb: Support different variants using a cfg struct

2026-06-04T09:50:04Z

The Linux kernel driver already had support for multiple hardware variants when the bcm2712 was added (see e.g. linux commit 10dbedad3c818 which is the last in a longer set of changes). This patch brings in this required infrastructure and adds a differentiation between 2711 and 2712 register layouts on top.

pinctrl: bcm283x: Add GPIO pull-up/down control for BCM2835 and BCM2711

2025-11-25T09:22:12Z

This patch adds support for configuring GPIO pull-up and pull-down resistors in the BCM283x pinctrl driver. It implements the brcm,pull device tree property to control pin bias settings. The implementation follows the hardware-specific pull control mechanisms: - BCM2835: two-step GPPUD register sequence - BCM2711: direct per-pin control registers This enables device tree configurations to specify pull-up, pull-down, or no bias for individual GPIO pins. Tested on Raspberry Pi boards with both BCM2835 and BCM2711 SoCs. Signed-off-by: Cibil Pankiras Reviewed-by: Matthias Brugger

arm: mach-bcm283x: Bring in some header files from tianocore

2024-10-27T23:24:13Z

These header files presumably duplicate things already in the U-Boot devicetree. For now, bring them in to get the ASL code and ACPI table code to compile.

rpi5: Use devicetree as alternative way to read IO base addresses

mmc: bcm2835-host: let firmware manage the clock divisor

2023-03-24T14:43:20Z

Newer firmware can manage the SDCDIV clock divisor register, allowing the divisor to scale with the core as necessary. Leverage this ability if the firmware supports it. Adapted from the following raspberrypi Linux kernel commit: bcm2835-sdhost: Firmware manages the clock divisor https://github.com/raspberrypi/linux/commit/08532d242d7702ae0add95096aa49c5e96e066e2 Signed-off-by: Vincent Fazio Signed-off-by: Peter Robinson

arm: rpi: fallback to max clock rate for MMC clock

2023-03-24T14:43:20Z

In rpi-firmware 25e2b597ebfb2495eab4816a276758dcc6ea21f1, the GET_CLOCK_RATE mailbox property was changed to return the last value set by SET_CLOCK_RATE. https://github.com/raspberrypi/firmware/issues/1619#issuecomment-917025502 Due to this change in firmware behavior, bcm2835_get_mmc_clock now returns a clock rate of zero since we do not issue SET_CLOCK_RATE. This results in degraded MMC performance. SET_CLOCK_RATE fixes the clock to a specific value and disables scaling so is not an ideal solution. Instead, fallback to GET_MAX_CLOCK_RATE in bcm2835_get_mmc_clock if GET_CLOCK_RATE returns zero. Signed-off-by: Vincent Fazio Signed-off-by: Peter Robinson
