From: Sricharan Ramabadhran <quic_srichara@xxxxxxxxxxx>
Add the qfprom, cpu clocks, A53 PLL and cpu-opp-table required for
CPU clock scaling.
Signed-off-by: Sricharan Ramabadhran <quic_srichara@xxxxxxxxxxx>
[ Added interconnect related entries, fix dt-bindings errors ]
Signed-off-by: Varadarajan Narayanan <quic_varada@xxxxxxxxxxx>
---
v5: Add opp-816000000
Have one item per line for clocks and clock-names
v4: s/gpll0/clk_ref/ in clock-names
s/apss-clock/clock/ in node name
v3: Remove L3_CORE_CLK from cpu node as it comes through icc-clk
v2: Add 'interconnects' to cpu nodes
Add 'opp-peak-kBps' to opp table
Add '#interconnect-cells' to apss_clk
Remove unnecessary comment
Fix dt-binding-errors in qfprom node
