Hello Thierry and Sowjanya,

I was trying today's next-20200304 and found that WiFi / Bluetooth got
broken:

[   23.130017] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd:
brcmf_proto_bcdc_msg failed w/status -110
[   23.130167] ieee80211 phy0: brcmf_cfg80211_get_channel: chanspec
failed (-110)

The fix is to replace TEGRA30_CLK_BLINK with TEGRA_PMC_CLK_BLINK in a
device-tree.

I'm not sure that the TEGRA30_CLK_BLINK breakage is expected to happen
because all clk/tegra/ PMC code is still in place. Please take a look,
thanks in advance.
