Dmitry Osipenko 187c001c49 soc/tegra: pmc: Fix completion of power-gate toggling 
[ Upstream commit c45e66a6b9 ]

The SW-initiated power gate toggling is dropped by PMC if there is
contention with a HW-initiated toggling, i.e. when one of CPU cores is
gated by cpuidle driver. Software should retry the toggling after 10
microseconds on Tegra20/30 SoCs, hence add the retrying. On Tegra114+ the
toggling method was changed in hardware, the TOGGLE_START bit indicates
whether PMC is busy or could accept the command to toggle, hence handle
that bit properly.

The problem pops up after enabling dynamic power gating of 3D hardware,
where 3D power domain fails to turn on/off "randomly".

The programming sequence and quirks are documented in TRMs, but PMC
driver obliviously re-used the Tegra20 logic for Tegra30+, which strikes
back now. The 10 microseconds and other timeouts aren't documented in TRM,
they are taken from downstream kernel.
