Subject: [PATCH 0/3] clk: bcm2835: critical clocks and parent selection

With the new patch 2 inserted between my previous pair, I think this
should cover Martin's bugs with clock disabling.

I tested patch 2 to be important on the downstream kernel: with the
DPI panel support added there, I was losing ethernet (my only I/O)
when the HDMI HSM hanging off of PLLD_PER got disabled due to
EPROBE_DEFER.

Eric Anholt (3):
  clk: bcm2835: Mark the VPU clock as critical
  clk: bcm2835: Mark GPIO clocks enabled at boot as critical.
  clk: bcm2835: Skip PLLC clocks when deciding on a new clock parent
