Subject: clk: pistachio: Fix wrong SDHost card speed
|
|
|
|
The SDHost currently clocks the card 4x slower than it
|
|
should do, because there is fixed divide by 4 in the
|
|
sdhost wrapper that is not present in the clock tree.
|
|
To model this add a fixed divide by 4 clock node in
|
|
the SDHost clock path.
|
|
|
|
This will ensure the right clock frequency is selected when
|
|
the mmc driver tries to configure frequency on card insert.
