Therefore it shouldn't use the same compatible used for the mt8365 infracfg clocks driver: mediatek,mt8365-infracfg. Since it currently does, probe errors are reported in the kernel logs: [ 0.245959] Failed to register clk ifr_pmic_tmr: -EEXIST [ 0.245998] clk-mt8365 1020e000.infracfg: probe with driver clk-mt8365 failed with error -17 This register space is used only as a syscon for bus control by the power domain controller, so in order to properly describe it and fix the errors, set its compatible to a distinct compatible used exclusively as a syscon, drop the clock-cells, and while at it rename the node to 'syscon' following the naming convention.
