Different card reader has different method to switch output voltage,
add this callback to let the card reader implement its individual switch
function.

Different card reader has different method to switch output voltage, so
we have to use the callback function provided by MFD driver to switch
output pad voltage.

Add callback function conv_clk_and_div_n to convert between SSC clock
and its divider N.
For rtl8411, the formula to calculate SSC clock divider N is different
with the other card reader models.

In function rtsx_pci_switch_clock, some variables, such as min_n, max_n,
and max_div, are not necessary. And those assigned values look very
obscure for others. It's more proper to use macro definitions here to
replace these variables.

Hi Chris and Samuel:
This patchset is trying to fix some bugs and some coding style issues.
Would you please help to merge it to v3.8 kernel?

I'll only take bug fixes for 3.8, even minor ones, and I don't see real bug
fixes here. Am I missing something ?

Hi Samuel:
The commits below are all bug fix ( fix rtl8411 specifically)
MFD:rtsx: Add callback function switch_output_voltage
MMC:rtsx: Using callback function to switch output voltage
MFD:rtsx: Add callback function conv_clk_and_div_n
The other commits are for coding style issues

Would you mind building a separate patchset for those 3, against e.g. a
vanilla 3.8-rc4 kernel ? Otherwise they won't apply cleanly against my
for-linus tree.

Hi Samuel:
Sure. I will do it.
Does it mean that the other commits only can be submitted to 3.9-rc?

Hi Samuel:
Sorry, pclinux is also me. I always mess the two mail accounts up.
I would like to repeat my question. Does it mean that the other commits
only can be submitted to 3.9-rc?
BR,
Wei WANG

Yes, that's how I prefer to handle it.

Submit them now. They stay in Samuel's tree and are tested in
linux-next until 3.8 is released. Then Samuel submits them during
the 3.9 merge window.
The merge window is for Samuel => Linus, it's not for you => Samuel.
If your code has not reached Samuel's tree before 3.8 has been
released then it's too late and it will be delayed for another few
months.
