From 84c53d84a0977afe78d88eb7aebbc5776816811f Mon Sep 17 00:00:00 2001 From: Teknoman117 <linux.robotdude@gmail.com> Date: Wed, 24 Jul 2013 03:02:20 -0700 Subject: [PATCH 4/4] Now this one is mine lol. Reading through the ti-abb documentation, I used their example and pulled the proper operating point settings for OPP1G, or the magic 1 GHz point on the Beagleboard xM. I've added the new operating points to the CPU entry and added the abb bindings for the beagleboard xm. Its nice that once again, we finally have a safe way of running the BBxM to its specifications after almost a year and a half of stagnating behind the kernel. Now 3.11-rc2 has 1 GHz support for the BBxM. So awesome ;) --- arch/arm/boot/dts/omap3-beagle-xm.dts | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) diff --git a/arch/arm/boot/dts/omap3-beagle-xm.dts b/arch/arm/boot/dts/omap3-beagle-xm.dts index 0f7cfc5..5f8ab16 100644 --- a/arch/arm/boot/dts/omap3-beagle-xm.dts +++ b/arch/arm/boot/dts/omap3-beagle-xm.dts @@ -16,9 +16,36 @@ cpus { cpu@0 { cpu0-supply = <&vcc>; + operating-points = < + /* kHz uV */ + 300000 1012500 + 600000 1200000 + 800000 1325000 + 1000000 1380000 + >; }; }; + abb: regulator-abb { + compatible = "ti,abb-v1"; + regulator-name = "abb"; + #address-cell = <0>; + #size-cells = <0>; + reg = <0x483072f0 0x8>, <0x48306818 0x4>; + reg-names = "base-address", "int-address"; + ti,tranxdone-status-mask = <0x4000000>; + clocks = <&sysclk>; + ti,settling-time = <30>; + ti,clock-cycles = <8>; + ti,abb_info = < + /* uV ABB efuse rbb_m fbb_m vset_m */ + 1012500 0 0 0 0 0 /* Bypass */ + 1200000 3 0 0 0 0 /* RBB mandatory */ + 1320000 1 0 0 0 0 /* FBB mandatory */ + 1380000 1 0 0 0 0 + >; + }; + memory { device_type = "memory"; reg = <0x80000000 0x20000000>; /* 512 MB */ -- 1.8.4.rc3
