From 1fb500476f609008ee1c499540af32c4fa5a19de Mon Sep 17 00:00:00 2001 From: Sheetal Date: Mon, 12 May 2025 05:17:42 +0000 Subject: [PATCH] ASoC: tegra: Update PLL rate for Tegra264 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The PLLs should be set with a VCO frequency in the 900MHz – 1GHz range to minimize jitter and ppm error for Tegra264. Add the PLLA rate accordingly. Therefore, use 983040000 frequency is for multiple of 8K frequencies and 993484800 frequency is for multiple of 11.025K frequencies.
