You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From 341604ad839d10314af51669fd454dc0aa2ef288 Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Tue, 3 Nov 2015 14:24:12 +0000 Subject: [PATCH] ASoC: arizona: fix range of OPCLK_REF The code was able to generate illegal OPCLK_REF values because the reference frequency tables listed all values of SYSCLK instead of valid values for OPCLK_REF clock. The maximum OPCLK_REF clock is 49.152MHz or 45.1584MHz.
