Subject: [PATCH] clk: qcom: apss-ipq6018: fix apcs_alias0_clk_src
|
||
|
|
|
||
|
|
While working on IPQ8074 APSS driver it was discovered that IPQ6018 and
|
||
|
|
IPQ8074 use almost the same PLL and APSS clocks, however APSS driver is
|
||
|
|
currently broken.
|
||
|
|
|
||
|
|
More precisely apcs_alias0_clk_src is broken, it was added as regmap_mux
|
||
|
|
clock.
|
||
|
|
However after debugging why it was always stuck at 800Mhz, it was figured
|
||
|
|
out that its not regmap_mux compatible at all.
|
||
|
|
It is a simple mux but it uses RCG2 register layout and control bits, so
|
||
|
|
utilize the new clk_rcg2_mux_closest_ops to correctly drive it while not
|
||
|
|
having to provide a dummy frequency table.
|
||
|
|
|
||
|
|
While we are here, use ARRAY_SIZE for number of parents.
|
||
|
|
|
||
|
|
Tested on IPQ6018-CP01-C1 reference board and multiple IPQ8074 boards.
|
||
|
|

||
