From 18d6d8fe4f24938985844d52c481b86fcce9d102 Mon Sep 17 00:00:00 2001 From: Haibo Chen Date: Thu, 9 Jun 2022 21:28:56 +0800 Subject: [PATCH] clk: imx93: use adc_root as the parent clock of adc1 When debug, find after system boot up, all adc register operation will trigger system hang, this is because the internal adc ipg clock is gate off. In dts, only reference the IMX93_CLK_ADC1_GATE, which is adc1, no one touch the adc_root, so adc_root will be gate off automatically after system boot up.
