Subject: [PATCH] clk: bcm2835: Mark GPIO clocks enabled at boot as
|
|
critical.
|
|
|
|
These divide off of PLLD_PER and are used for the ethernet and wifi
|
|
PHYs source PLLs. Neither of them is currently represented by a phy
|
|
device that would grab the clock for us.
|
|
|
|
This keeps other drivers from killing the networking PHYs when they
|
|
disable their own clocks and trigger PLLD_PER's refcount going to 0.
|
|
|
|
v2: Skip marking as critical if they aren't on at boot.
