From b7dbe349e1eb5a1c07b58da83d8ee60030682a3a Mon Sep 17 00:00:00 2001 From: "H. Nikolaus Schaller" Date: Wed, 11 Sep 2019 19:47:08 +0200 Subject: ARM: dts: omap34xx & omap36xx: replace opp-v1 tables by opp-v2 for With the driver installed, we can change the opp-v1 table format to opp-v2. In addition, move omap3 from whitelist to blacklist in cpufreq-dt-platdev in the same patch, because doing either first breaks operation and may make trouble in bisect. We also can remove opp-v1 table for omap3-n950-n9 since its 1GHz capability is now automatically detected. We also fix a wrong OPP4 voltage for omap3430 which must be 0.6V + 54*12.5mV = 1275mV. Otherwise the twl4030 driver will reject this OPP. Note: the high speed OPPs that were not available in the opp-v1 tables are tagged "turbo-mode;" which means they are not automatically activated by the govenors or cpu-freq. To enable you have to write echo 1 >/sys/devices/system/cpu/cpufreq/boost Note: to hard disable an OPP in a board.dts file use e.g. &cpu0_opp_table: { /delete-node/ opp1g-1000000000; /* do not use */ }; or alternatively: &cpu0_opp_table: { opp1g-1000000000 { status = "disabled"; /* do not use */ }; }; Signed-off-by: H.
