Subject: [PATCH] clk: bcm2835: Mark the VPU clock as critical
|
|
|
|
The VPU clock is also the clock for our AXI bus, so we really can't
|
|
disable it. This might have happened during boot if, for example,
|
|
uart1 (aux_uart clock) probed and was then disabled before the other
|
|
consumers of the VPU clock had probed.
|
|
|
|
v2: Rewrite to use a .flags in bcm2835_clock_data, since other clocks
|
|
will need this too.
