Subject: [PATCH v2 08/14] scsi: ufs: host: ufs-exynos: Add EXYNOS_UFS_OPT_UFSPR_SECURE option
Date: Tue, 23 Apr 2024 21:50:00 +0100 [thread overview]
Message-ID: <20240423205006.1785138-9-peter.griffin@linaro.org> (raw)
In-Reply-To: <20240423205006.1785138-1-peter.griffin@linaro.org>
This option is intended to be set on platforms whose ufspr
registers are only accessible via smc call (such as gs101).
Signed-off-by: Peter Griffin <peter.griffin@linaro.org>
Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
Tested-by: Will McVicker <willmcvicker@google.com>
