[PATCH V2 0/3] at24: parse OF-data

Here is the second round of this series: * 1/3 now uses __be32 instead of u32. * 2/3 is new and adds some more sanity checks * 3/3 is unchanged Grant, I hope you can pick 2/3 as well. Should make things easier and it is just a misc-driver (which I maintain) :) Wolfram Sang (3): misc: at24: par

Information about the pagesize and read-only-status may also come from the devicetree. Parse this data, too, and act accordingly. While we are here, change the initialization printout a bit. write_max is useful to know to detect performance bottlenecks, the rest is superfluous. Signed-off-by: Wolf
