From: Charles Keepax Date: Fri, 7 Jun 2024 10:34:23 +0000 (+0100) Subject: spi: cs42l43: Drop cs35l56 SPI speed down to 11MHz X-Git-Tag: v6.10-rc5~9^2~5 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=60980cf5b8c8cc9182e5e9dbb62cbfd345c54074;p=thirdparty%2Fkernel%2Flinux.git spi: cs42l43: Drop cs35l56 SPI speed down to 11MHz Some internals of the cs35l56 can only support SPI speeds of up to 11MHz. Whilst some use-cases could support higher rates, keep things simple by dropping the SPI speed down to this avoid any potential issues.
