Subject: [PATCH v7 4/4] mmc: sdhci-tegra: Enable MMC_CAP2_ALT_GPT_TEGRA
Date: Fri, 20 Aug 2021 03:45:36 +0300	[thread overview]
Message-ID: <20210820004536.15791-5-digetx@gmail.com> (raw)
In-Reply-To: <20210820004536.15791-1-digetx@gmail.com>

Tegra20/30/114/124 Android devices place GPT at a non-standard location.
Enable GPT entry scanning at that location.
