dm: core: Default to using DEVRES outside of xPL

2026-01-09T15:08:14+00:00

The devm alloc functions that we have may follow the Linux kernel model
where allocations are (almost always) automatically free()'d. However,
quite often we don't enable, in full U-Boot, the tracking and free()'ing
functionality. This in turn leads to memory leaks because the driver
author expects that since the functions have the same name as in the
Linux Kernel they have the same behavior. In turn we then get
functionally correct commits such as commit 00e1fed93c8c ("firmware:
ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually
add these calls. Rather than manually tracking allocations and
implementing free()s, rework things so that we follow expectations by
enabling the DEVRES functionality (outside of xPL phases).

This turns DEVRES from a prompted symbol to a symbol that must be
select'd, and we now remove our non-managed alloc/free functions from
outside of xPL builds.

pinctrl: mscc: Add gpio and pinctrl for Jaguar2 SOC family

2019-01-16T12:56:43+00:00

The Jaguar2 SOC family has 63 gpio pins therefore I extended mscc-common
to support new numbe of pins and remove any platform dependency from
mscc-common.

pinctrl: mscc: Add gpio and pinctrl driver for MSCC MIPS SoCs (VcoreIII based)

2018-12-19T14:23:01+00:00

This driver supports the pin and gpio controller found in the Ocelot and
Luton SoCs.

The driver was inspired from the pinctrl driver in Linux, but was
simplified and was modified to allow supporting an other SoCs (Luton).

For Ocelot and Luton the controller is the same, only the pins to program
differ.
