From 11f296870659e1375e7116a859458b254cc3156f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?M=C3=A5ns=20Rullg=C3=A5rd?= Date: Mon, 28 Oct 2013 23:19:53 +0000 Subject: ti814x: Fix illegal use of FP ops in clock_ti814x.c The function pll_sigma_delta_val uses "float" data which is not correct. The exact "why" of this mangling is lost to history, but this changes us to equivalent non-FP math to get the same results.
