We have received your E-mail and are in the process of redirecting it. Your comments and questions we'll probably be reviewed by our Help Analysis Department in (the nearest) due time. If any (or all) of your suggestions are deemed of value they will most likely be included in a future release of the kernel. Please note that based on our preliminary present schedule, we see a possible opening for 3.14.7-rc5 or thereafter. We would like to thank you for your interest in our products and are looking forward to hearing from you in the future. mit Hochachtungsvoll, Your Friendly Kernel Team On Thu, Jul 18, 2013 at 11:00 AM, Arthur Radley < misterarthurrad...@gmail.com> wrote: > Markku Pesonen <tourula <at> gmail.com> writes: > > > > > alex lupu wrote: > > > BTW, what's a "Generic RTC class"? > > > Would save me some research time ... > > > > Generic RTC class supports many different RTC chips found on all kinds > > of hardware, unlike the legacy PC RTC driver. > > > > I assume you are using "make menuconfig".
