Subject: [PATCH 1/5] mmc: am654_sdhci: Add MMC_HS_52 to timing data
Date: Tue, 8 Apr 2025 12:05:23 -0500 [thread overview]
Message-ID: <20250408170527.2832563-2-jm@ti.com> (raw)
In-Reply-To: <20250408170527.2832563-1-jm@ti.com>
This patch adds MMC_HS_52 to the timing data structure.
Previously, this bus mode tap settings were not populated and
were instead populated for MMC_HS which is a different bus mode
up to 26MHz. Since we intended these settings according to the
device data sheet[0] for MMC_HS_52 up to 52MHz, populate MMC_HS
tap settings for MMC_HS_52.
While we are here, fix typo in ti,itap-del-sel-mms-hs.
