[PATCH] arm64: tegra: Add pinctrl nodes for Tegra264

Posted by pshete@nvidia.com 2 months ago

From: Prathamesh Shete <pshete@nvidia.com>

Add the three pin controller (MAIN, UPHY, AON) device tree
nodes found on Tegra264.

Changes in v2:
  - Replaces the v1 "arm64: defconfig: make Tegra238 and Tegra264
    Pinctrl ..." patch (now unnecessary thanks to the 'default m if
    ARCH_TEGRA_{238,264}_SOC' Kconfig change) by adding the three pin
    controller nodes (pinmux, pinmux_aon, pinmux_uphy) to
    tegra264.dtsi.

This patch does not replace the defconfig patch. The defconfig patch was 
dropped which is unrelated to this patch. This patch was added for V2 
for completeness. So all we need to say here is that this was added for 
V2 and that's all.

Obviously something went completely wrong with the patch series 
generation and is not properly added to the series. Please fix up for V3.

What is this doing in the middle of other v2 patchset?

Best regards,
