Merge patch series "Qualcomm: cleanup OF_LIVE fixup and fix RB1/2"

2025-05-02T14:38:27+00:00

Caleb Connolly  says:

Introduce a new event to signal that the live tree has been built,
allowing boards to perform fixups on the tree before devices are bound.
Crucially this allows for devices to be enabled or disabled, but also
allows for properties that are parsed during the bind stage to be
modified (such as dr_mode for dwc3).

With this in place, mach-snapdragon is switched over to use the event
and some hacky U-Boot specific DT overrides (which had to be undone
prior to booting an image) are removed in favour of fixing up the
livetree (which is not passed on to further boot stages).

Finally, some minor fixes are made for the QCM2290 RB1 board, the sdcard
is enabled and it now uses USB host mode in U-Boot like it's bigger
sibling the RB2.

pinctrl: qcom: qcm2290: fix off by 1 in pin_count

2025-05-02T14:38:03+00:00

There are 134 pins not 133, oops! This fixes the sdcard on the RB1 as
the pins now all get configured correctly.

pinctrl: qcom: handle reserved ranges

2025-04-11T13:30:21+00:00

Some Qualcomm boards feature reserved ranges of pins which are protected
by firmware. Attempting to read or write any registers associated with
these pins results the board resetting.

Add support for parsing these ranges from devicetree and ensure that the
pinctrl and GPIO drivers don't try to interact with these pins.

drivers: pinctrl: Add Qualcomm SDM630/660 TLMM driver

2025-04-11T13:25:51+00:00

Add support for TLMM pin controller block (Top Level Mode
Multiplexer) on SDM630/660 SoCs, with support for special pins.

Correct pin configuration is required for working debug UART
and eMMC/SD cards.

SDM630 and SDM660 TLMM blocks are the same.

2025-03-17T13:38:17+00:00

Presently, get_function_mux returns an unsigned int and cannot
differentiate between failure and correct function value. Change its
return type to int and check for failure in the caller.

Additionally, updated drivers/pinctrl/qcom/pinctrl-*.c to accommodate the
above return type change. Only compile test done.

pinctrl: qcom: sm8250: fix pin count

2025-02-26T13:48:27+00:00

The pin count wasn't updated when the special pins were added, as a
result it was never possible to configure the special pins on SM8250
boards.

Fix the pin count and allow the special pins to be configured. This
fixes sdcard support on the RB5.
