* Paul Walmsley <paul@xxxxxxxxx> [081112 10:53]: > Hello, > > this series fixes a bug in the OMAP3 DPLL rate rounding code that will > attempt to program the DPLL to use an internal clock frequency that > does not exist in the FREQSEL table in 34xx TRM 4.7.6.2. This mostly > seems to generate warnings, but can potentially hang the system. > > As part of this process, improve the DPLL rate rounding algorithm to > start from a low divider (N) and count up; this should result in fewer > passes through the loop. > > Tested on 3430SDP ES2 and a custom ES3 board. Thanks to Peter de Schrijver > <peter.de-schrijver@xxxxxxxxx> for help with these patches. Pushing this series today to l-o.
