As I assume you will send a v2 (due to kbuild issue) remove empty line
please.
Sure. I will do. (But unfortunately it will not happen very soon :( )
No pb.
In the meantime comments and testing are appreciated. Also, I forgot
to say that, if one wants to try this, he/she will need the bootloader
to set properly the 48MHz clk for SD (for afboot use my tree -
pull-req pending on Maxime Coquelin tree). For clk driver probably my
patch for making it aware of the 48MHz setting is still needed (I've
not looked into other recent clk patches yet)..
did you see patches sent by Gabriel Fernandez: "[PATCH 0/6] Add STM32F4
missing clocks". This series should add support for 48 MHz. So it is
needed to check first if Gabriel's series is enough.
Thanks
Alex
