Subject: [PATCH] clk: bcm2835: Don't rate change PLLs on behalf of dividers.
|
|
|
|
Our core PLLs are intended to be configured once and left alone. With
|
|
the flag set, asking to set the PLLD_DSI1 clock rate would change PLLD
|
|
just to get closer to the requested DSI clock, thus changing PLLD_PER,
|
|
the UART and ethernet PHY clock rates downstream of it, and breaking
|
|
ethernet.
