Álvaro Fernández Rojas 8c405cdccc bcm27xx: add 6.6 kernel patches 
The patches were generated from the RPi repo with the following command:
git format-patch v6.6.34..rpi-6.1.y

Some patches needed rebasing and, as usual, the applied and reverted, wireless
drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0511/1085] pinctrl: bcm2712 pinctrl/pinconf driver
pinctrl: bcm2712: Reject invalid pulls
Reject attempts to set pulls on aon-sgpios, and fix pull shift
values.
pinctrl: bcm2712: Add 7712 support, fix 2712 count
Signed-off-by: Phil Elwell <phil@raspberrypi.com>
pinctrl-bcm2712: add EMMC pins so pulls can be set
These pins have pad controls but not mux controls. They look enough like
GPIOs to squeeze in at the end of the list though.
pinctrl: bcm2712: correct BCM2712C0 AON_GPIO pad pull control offset
Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
pinctrl: bcm2712: on C0 the regular GPIO pad control register moves too
Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
pinctrl: bcm2712: Implement (partially) pinconf_get
Signed-off-by: Phil Elwell <phil@raspberrypi.com>
pinctrl: bcm2712: Convert to generic pinconf
Remove the legacy brcm,* pin configuration support and replace it with
a proper generic pinconf interface, using named functions instead of
alt function numbers. This is nicer for users, less error-prone, and
immune to some of the C0->D0 changes.
Signed-off-by: Phil Elwell <phil@raspberrypi.com>
pinctrl: bcm2712: Remove vestigial pull parameter
Now the legacy brcm, pinconf parameters are no longer supported, this
custom pin config parameter is not needed.
Signed-off-by: Phil Elwell <phil@raspberrypi.com>
pinctrl: bcm2712: Guard against bad func numbers
Signed-off-by: Phil Elwell <phil@raspberrypi.com>
pinctrl: bcm2712: A better attempt at D0 support
The BCM2712D0 sparse pinctrl maps play havoc with the old GPIO_REGS
macro, so make the bit positions explicit. And delete the unwanted
GPIO and pinmux declarations on D0.
Note that a Pi 5 with D0 requires a separate DTS file with "bcm2712d0"
compatible strings.
Signed-off-by: Phil Elwell <phil@raspberrypi.com>
pinctrl: bcm2712: Delete base register constants
BCM2712D0 deletes many GPIOs and their associated mux and pad bits,
so much so that the offsets to the start of the pad control registers
changes. Remove the constant offsets from the *GPIO_REGS macros,
compensating by adjusting the per-GPIO values.
