Subject: [PATCH] STOPSHIP: clk: mediatek: mt8192-msdc: Set CLK_IGNORE_UNUSED
on CLK_MSDC_AXI_WRAP
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
During clk_disable_unused(), the status of CLK_MSDC_AXI_WRAP is read in
order to determine whether it should be disabled. However, the simple
act of reading this clock, causes i2c0 to fail subsequent operations.
Set the CLK_IGNORE_UNUSED on this clock so it is not even read, fixing
the side-effect issue in the i2c0 bus.
