Subject: [PATCH 0/2] mmc: jz4740: Don't change parent clock rate for some SoCs
Date: Tue, 8 Nov 2022 07:52:58 +0300 [thread overview]
Message-ID: <20221108045300.2084671-1-lis8215@gmail.com> (raw)
Some SoCs have one clock divider for all MMC units, thus changing one
affects others as well. This leads to random hangs and memory
corruptions, observed on the JZ4755 based device with two MMC slots
used at the same time.
List of SoCs affected includes: JZ4725b, JZ4755, JZ4760 and JZ4760b.
The MMC core has its own clock divisor and it goes to the first plan in
that case.
