pinctrl: tegra: PINCTRL_TEGRA264 should depend on ARCH_TEGRA

2026-06-11T12:04:44+00:00

The NVIDIA Tegra264 MAIN, AON, and UPHY pin controllers are only present on NVIDIA Tegra264 SoCs. Hence add a dependency on ARCH_TEGRA, to prevent asking the user about this driver when configuring a kernel without NVIDIA Tegra SoC support.

pinctrl: tegra238: add missing AON pin groups

2026-06-11T12:03:24+00:00

Add 24 pin groups on ports EE, FF, GG and HH to the AON pin controller group table (tegra238_aon_groups[]). Their pin arrays, drive-group macros and pin descriptors were already defined, but the matching PINGROUP() entries were not present, so these pins could not be muxed or configured through the AON pin controller. The pin arrays were not referenced, so the build emitted -Wunused-const-variable warnings, and commit 119de2c33d96 ("pinctrl: tegra238: remove unused entries") removed three of them. Restore those arrays and add the full set of PINGROUP() entries to make the pins usable.

pinctrl: tegra: Enable easier compile testing

2026-04-28T09:08:48+00:00

Currently NVIDIA Tegra pin controller drivers cannot be compile tested, unless ARCH_TEGRA is selected. That partially defeats the purpose of compile testing, since ARCH_TEGRA is pulled when building platform kernels. Solve it and allow compile testing independently of ARCH_TEGRA choice which requires few less usual changes: 1. Descent in Makefile in to drivers/pinctrl/tegra/ unconditionally, because there is no menu option. 2. Depend on COMMON_CLK for PINCTRL_TEGRA20, because it uses clk_register_mux().
