[PATCH] soc/tegra: pmc: fix #ifdef block in header

From: Arnd Bergmann

Date: Tue Jun 16 2026 - 15:58:19 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

When build testing on ARM without the PMC driver, the other drivers
fail to link:

ld.lld: error: undefined symbol: tegra_pmc_core_domain_state_synced
>>> referenced by regulators-tegra30.c
>>> drivers/soc/tegra/regulators-tegra30.o:(tegra30_regulator_balance_voltage) in archive vmlinux.a
>>> referenced by regulators-tegra20.c
>>> drivers/soc/tegra/regulators-tegra20.o:(tegra20_core_rtc_update) in archive vmlinux.a

Adapt the checks in the header to cover both cases on other architectures
and without PMC.

Fixes: 8318af5dd29c ("soc/tegra: pmc: Move legacy code behind CONFIG_ARM guard")
