Or is there some other corporation I don't know about?

This patch adds OPPs to the CA15 DT node and a max8973 DT node to support clock and voltage scaling, using the cpufreq-cpu0 CPUFreq driver. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski+renesas@gmail.com> --- v2: Subject to Mark acking v2 of my max8973 DT patch, this should be the updated version of my original ape6evm CPUFreq patch. This version puts all max8973 regulator bindings directly under the respective I2C device node instead of creating 2 additional levels. arch/arm/boot/dts/r8a73a4-ape6evm.dts | 22 ++++++++++++++++++++++ 1 files changed, 22 insertions(+), 0 deletions(-)
