From: Stefan Agner Date: Thu, 28 Apr 2016 21:07:03 +0000 (-0700) Subject: clk: imx7d: fix ahb clock mux 1 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=92a847e3609a8d00bcbe8bdfacbcbbca03135410;p=linux-beck.git clk: imx7d: fix ahb clock mux 1 The clock parent of the AHB root clock when using mux option 1 is the SYS PLL 270MHz clock. This is specified in Table 5-11 Clock Root Table of the i.MX 7Dual Applications Processor Reference Manual. While it could be a documentation error, the 270MHz parent is also mentioned in the boot ROM configuration in Table 6-28: The clock is by default at 135MHz due to a POST_PODF value of 1 (=> divider of 2).
