linux-toradex.git/drivers/clk, branch v3.12.42 Linux kernel for Apalis and Colibri modules clk-gate: fix bit # check in clk_register_gate() 2015-03-16T13:58:21+00:00 Sergei Shtylyov sergei.shtylyov@cogentembedded.com 2014-12-24T14:43:27+00:00 13538bcabe53f06d64e65f6dd101f3ba07f3c9c0 commit 2e9dcdae4068460c45a308dd891be5248260251c upstream. In case CLK_GATE_HIWORD_MASK flag is passed to clk_register_gate(), the bit # should be no higher than 15, however the corresponding check is obviously off- by-one.

For all pll-s on sun6i n == 0 means use a multiplier of 1, rather then 0 as it means on sun4i / sun5i / sun7i. n_start = 1 is already correctly set for sun6i pll6, but was missing for pll1, this commit fixes this.

clk: prevent erronous parsing of children during rate change 2014-10-13T13:41:41+00:00 Tero Kristo t-kristo@ti.com 2014-08-21T13:47:45+00:00 3386c069c54344797c4d2da55ebef2f555a7a4a3 commit 067bb1741c27c8d3b74ac98c0b8fc12b31e67005 upstream. In some cases, clocks can switch their parent with clk_set_rate, for example clk_mux can do this in some cases. Current implementation of clk_change_rate uses un-safe list iteration on the clock children, which will cause wrong clocks to be parsed in case any of the clock children change their parents during the change rate operation. Fixed by using the safe list iterator instead. The problem was detected due to some divide by zero errors generated by clock init on dra7-evm board, see discussion under http://article.gmane.org/gmane.linux.ports.arm.kernel/349180 for details.
