[PATCH] arm64: dts: renesas: sparrow-hawk: Mark OTP and HSCIF0 pins as bootph-all

From: Marek Vasut

Date: Mon Jan 12 2026 - 18:46:50 EST


The U-Boot SPL is responsible for initializing the hardware and it does
also initialize HSCIF0 and its pinmux, mark the HSCIF0 pinmux as needed
in all bootloader stages. The SPL also uses OTP to determine the exact
V4H SoC variant during DRAM initialization, to determine which is the
maximum allowed DRAM rate, mark OTP as required in all bootloader stages
as well.
