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: renesas: r8a779h0: Remove STPWT_EXTFXR

2025-11-13T15:30:26+00:00

Rev.0.81 of the R-Car V4M Series Hardware User’s Manual removed the
"STPWT_EXTFXR" signal from the pin control register tables.  As this is
further unused in the pin control driver, it can be removed safely.

pinctrl: renesas: Add initial R8A78000 R-Car X5H PFC tables

2025-11-06T19:09:59+00:00

Add initial pin control tables for the Renesas R-Car X5H R8A78000 SoC.
This SoC is the first one which includes custom DRV register handling,
different from previous generations due to change in DRV register bit
layout.

pinctrl: renesas: Move drive strength configuration into sh_pfc_soc_operations

2025-11-06T19:09:59+00:00

The upcoming Renesas R-Car Gen5 uses different mapping of bits in DRV
control register, which is incompatible with existing DRV register bit
mapping. Add .set_drive_strength callback into sh_pfc_soc_operations
and call it from sh_pfc_pinconf_set(), to allow each SoC specific PFC
driver to implement replacement .set_drive_strength. Make the current
sh_pfc_pinconf_set_drive_strength() non-static, rename it with rcar_
prefix, and pass it as .set_drive_strength for existing PFC drivers.
This is a preparatory patch for R-Car Gen5, no functional change.

[Marek: Consistently use .set_drive_strength() and pass exisiting
        sh_pfc_pinconf_set_drive_strength() as its parameter for
