From 9563d7290f7e06f1d64ed801c2cef7c802715d64 Mon Sep 17 00:00:00 2001 From: Alex Frid Date: Mon, 3 Dec 2012 15:01:27 -0800 Subject: ARM: tegra11: clock: Support cbus scaling below Fmax@Vmin So far, frequencies of graphics engines on cbus are scaled along the respective DVFS operating points only, which effectively set minimum scaling frequency to Fmax@Vmin level. This commit extended cbus scaling range down to the minimum rate supported by the bus parent pll with the regular frequency steps of 48MHz.
