[PATCH 1/3] arm: mach-k3: am62: add &main_uart6 to clock and pwr tree

rs at ti.com rs at ti.com
Tue Mar 17 23:37:58 CET 2026


From: Bryan Brattlof <bb at ti.com>

The pocketbeagle2 uses the main_uart6 as the debug console. To get debug
console prints at the R5 SPL stage, add the &main_uart6 to the R5 clk
and dev data so we can configure the uart as early as possible during
the bootup of the pocketbeagle2
