[PATCH 0/4] pinctrl: More compile testing

[Krzysztof Kozlowski]

Follows https://lore.kernel.org/r/20260410103005.163128-2-krzysztof.kozlowski@oss.qualcomm.com/
but should not depend on it anyhow.

More compile testing means better bot coverage. Plus having ||
COMPILE_TEST and obj-CONFIG_ARCH_FOO is kind of pointless.

I built these on arm, arm64, i386, x86_64, sparc, m68k, s390, riscv and
powerpc. Branch is pushed also to LKP, so more build tests will follow.

Best regards,
Krzysztof

[PATCH 1/4] pinctrl: realtek: Enable compile testing

[Krzysztof Kozlowski]

Enable compile testing for Realtek pin controller drivers for increased
build and static checkers coverage.  PINCTRL_RTD uses
pinconf_generic_dt_node_to_map(), thus needs OF.

[PATCH 2/4] pinctrl: aspeed: Enable compile testing outside of ARCH_ASPEED

[Krzysztof Kozlowski]

Since inception in commit 4d3d0e4272d8 ("pinctrl: Add core support for
Aspeed SoCs"), the Aspeed pin controller drivers cannot be compile
tested, unless ARCH_ASPEED is selected.  .  That partially defeats the
purpose of compile testing, since ARCH_ASPEED is pulled when building
platform kernels.

Enable compile testing for Realtek pin controller drivers for increased

Hi Krzysztof,

Small nit, but this looks like a copy-paste error from the other patch.

	Realtek -> VIA/Wondermedia (or vt8500, whatever you prefer)

Best,

[PATCH 4/4] ARM: realtek: MAINTAINERS: Include pin controller drivers

[Krzysztof Kozlowski]

No dedicated maintainers are shown for Realtek SoC pin controllers,
except pinctrl subsystem maintainer, which means reduced review and
impression of abandoned drivers.  Pin controller drivers are essential
part of an SoC, so in case of lack of dedicated entry at least cover it
by the SoC platform maintainers.

This patch should go via Realtek SoC maintainers, not pinctrl.
