Subject: [PATCH v4 1/5] phy: tegra: xusb: Protect Tegra186 soc with config
Date:   Wed, 9 Oct 2019 10:43:39 +0800

As xusb-tegra186.c will be reused for Tegra194, it would be good to
protect Tegra186 soc data with CONFIG_ARCH_TEGRA_186_SOC. This commit
also reshuffles Tegra186 soc data single CONFIG_ARCH_TEGRA_186_SOC
will be sufficient.
