From f278f05e748cdce3d7994c5de7cc2f02cc185f65 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Mon, 20 May 2019 22:03:17 +0200 Subject: [PATCH] clk: meson: meson8b: add the cts_amclk clocks Add the I2S master clock also referred as cts_amclk. The setup for this clock is identical to GXBB, so this ports commit 4087bd4b21702d ("clk: meson: gxbb: add cts_amclk") to the Meson8/Meson8b/Meson8m2 clock driver.
