ARM: dts: OMAP443x: Add CPU OPP table (e77049bb) · Commits · 戴 / test

Add DT OPP table for OMAP443x family of devices. This data is decoded by OF with of_init_opp_table() helper function. OPP data here is based on existing opp4xxx_data.c Since the omap4460 OPP tables would be different from OMAP443x, introduce an new omap443x.dtsi for 443x specific entries and use existing omap4.dtsi as the common dtsi file for all OMAP4 platforms. This is in preparation to use generic cpufreq-cpu0 driver for device tree enabled boot. Legacy non device tree enabled boot continues to use omap-cpufreq.c and opp4xxx_data.c. Signed-off-by:
