Subject: [PATCH v2 0/3] Set eMMC clock parent to default
Date: Tue, 29 Apr 2025 11:33:34 -0500	[thread overview]
Message-ID: <20250429163337.15634-1-jm@ti.com> (raw)

This series was split-off from "Misc MMC updates" patch series [0] and the
original patch further divided into three to help with backporting as per
review comments [1].

This series sets clock parent for eMMC to the default clock parent
MAIN_PLL0_HSDIV5_CLKOUT for am62, am62a, & am62p/j722s SoCs. Software (DM)
does not switch MMC clock parent correctly as per the Arasan IP requirement
to hold the IP in reset while clock source is switched. Since muxes to
switch clock parent are not glitch-free and the default parent is tested
and working fine, switch to the default as a preventative action.

Changes since v1:
- split original patch into three
- add cover-letter
- reword patch descriptions
- add review tags
