Subject: [PATCH v2 1/5] arm64: dts: ti: k3-am6*: Set eMMC clock parents to default
Date: Thu, 17 Apr 2025 18:30:36 -0500	[thread overview]
Message-ID: <20250417233040.3658761-2-jm@ti.com> (raw)
In-Reply-To: <20250417233040.3658761-1-jm@ti.com>

Set eMMC clock parents to the defaults which is MAIN_PLL0_HSDIV5_CLKOUT
for eMMC. This change is necessary since DM is not implementing the
correct procedure to switch PLL clock source for eMMC and we have a
non-glich-free mux. To remove any potential issues, lets switch back to
the defaults.

Fixes: c37c58fdeb8a ("arm64: dts: ti: k3-am62: Add more peripheral nodes")
Fixes: d3ae4e8d8b6a ("arm64: dts: ti: k3-am62a-main: Add sdhci0 instance")
Fixes: b5080c7c1f7e ("arm64: dts: ti: k3-am62p: Add nodes for more IPs")
