pinctrl: bcm: Add STB family pin controller driver

2025-09-08T12:23:42+00:00

This driver provide pin muxing and configuration functionality
for BCM2712 SoC used by RPi5. According to [1] this chip is an
instance of the one used in Broadcom STB  product line.

arm64: bcmbca: Make BCM4908 drivers depend on ARCH_BCMBCA

2022-08-15T16:55:34+00:00

With Broadcom Broadband arch ARCH_BCMBCA supported in the kernel, this
patch series migrate the ARCH_BCM4908 symbol to ARCH_BCMBCA. Hence
replace ARCH_BCM4908 with ARCH_BCMBCA in subsystem Kconfig files.

2022-03-28T18:52:53+00:00

Pull pin control updates from Linus Walleij:
 "No core changes this time. Just new driver code and improvements!

  New drivers:

   - New driver for the Broadcom BCM4908 SoC.

   - New subdriver for Tesla FSD (Full Self Driving) SoC, a derivative
     of the Samsung Exynos pin control driver.

   - New driver for the Amlogic Meson S4 SoC.

   - New driver for the Sunplus SP7021 SoC.

   - New driver for the Microsemi Ocelot family ServalT SoC.

   - New subdriver for Intel Alder Lake-M SoC.

   - New subdriver for Intel Ice Lake-N SoC, including PCH support.

   - New subdriver for Renesas R8A779F0 SoC.

   - New subdriver for Mediatek MT8186 SoC.

   - New subdriver for NXP Freescale i.MX93 SoC.

   - New driver for Nuvoton WPCM450 SoC.

   - New driver for Qualcomm SC8280XP SoC.

  Improvements:

   - Wakeup support on Samsung Exynos850 and ExynosAutov9.

   - Serious and voluminous maintenance cleanup and refactoring in the
     Renesas drivers. Mainly sharing similar data between the different
     SoC subdrivers.

   - Qualcomm SM8450 EGPIO support.

   - Drive strength support on the Mediatek MT8195.

   - Add some missing groups and functions to the Ralink RT2880"

pinctrl: bcm63xx: fix unmet dependency on REGMAP for GPIO_REGMAP

2022-01-30T01:44:00+00:00

When PINCTRL_BCM63XX is selected,
and REGMAP is not selected,
Kbuild gives the following warning:

WARNING: unmet direct dependencies detected for GPIO_REGMAP
  Depends on [n]: GPIOLIB [=y] && REGMAP [=n]
  Selected by [y]:
  - PINCTRL_BCM63XX [=y] && PINCTRL [=y]

This is because PINCTRL_BCM63XX
selects GPIO_REGMAP without selecting or depending on
REGMAP, despite GPIO_REGMAP depending on REGMAP.

This unmet dependency bug was detected by Kismet,
a static analysis tool for Kconfig. Please advise
if this is not the appropriate solution.

pinctrl: bcm: add driver for BCM4908 pinmux

2022-01-25T00:42:13+00:00

BCM4908 has its own pins layout so it needs a custom binding and a Linux

pinctrl: bcm: ns: use generic groups & functions helpers

2021-12-26T03:22:11+00:00

This simplifies ns driver and gets rid of ~70 lines of code.

"const" had to be dropped from "struct ns_pinctrl_group" @pins to match
"struct group_desc" @pins and pinctrl_generic_add_group(). Otherwise it
would cause:

drivers/pinctrl/bcm/pinctrl-ns.c: In function 'ns_pinctrl_probe':

Add depends on OF so we don't get weird build errors on
randconfig.

Also order selects the same as the other drivers for
pure aestetic reasons.

pinctrl: add a pincontrol driver for BCM6318

2021-03-29T10:20:09+00:00

Add a pincontrol driver for BCM6318. BCM6318 allows muxing most GPIOs
to different functions. BCM6318 is similar to BCM6328 with the addition
of a pad register, and the GPIO meaning of the mux register changes
based on the GPIO number.
