Subject[PATCH 5.17 175/343] clk: ti: Preserve node in ti_dt_clocks_register()
Date
From: Tony Lindgren <tony@atomide.com>

[ Upstream commit 80864594ff2ad002e2755daf97d46ff0c86faf1f ]

In preparation for making use of the clock-output-names, we want to
keep node around in ti_dt_clocks_register().

This change should not needed as a fix currently.
