Subject: [PATCH 4/9] clk: qcom: krait-cc: register REAL qsb fixed clock
|
|
|
|
With some tools it was discovered the real frequency of the qsb fixed
|
|
clock. While not 100% correct it's still better than using 1 as a dummy
|
|
frequency.
|
|
Correctly register the qsb fixed clock with the frequency of 225 MHz
|
|
instead of 1.
