From: Xianwei Zhao Date: Fri, 24 May 2024 06:35:09 +0000 (+0800) Subject: spi: meson-spicc: set SPI clock flag CLK_SET_RATE_PARENT X-Git-Tag: v6.11-rc1~205^2~29 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=022bd9c520d8f9dd51f29326eb369b8ec958f687;p=thirdparty%2Flinux.git spi: meson-spicc: set SPI clock flag CLK_SET_RATE_PARENT Add SPI clock flag CLK_SET_RATE_PARENT for using pclk as parent clock. This gives SPI more flexibility in frequency selection.
