Subject: [PATCH] ARM: dts: stm32: enable STM32MP1 crypto/CRC accelerators unconditionally
Date: Tue, 19 Jan 2021 10:52:39 +0100 [thread overview]
Message-ID: <20210119095241.17888-1-a.fatoum@pengutronix.de> (raw)
There is no SoC-external hardware support needed for the hash1, rng1,
crc1 and cryp1 IP blocks to function. Enable them thus unconditionally
instead of replicating their enablement in board device trees.
Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de>
