  mfd: rtsx: replace TAB by SPC after #define
  mfd: rtsx: place register address and values togather
  mfd: rtsx: add debug info when access register failed
  mfd: rtsx: update PETXCFG address
  mfd: rtsx: update driving settings
  mfd: rtsx: update phy register
  mfd: rtsx: remove LCTLR defination
  mfd: rtsx: add support for rts524A
  mfd: rtsx: add support for rts525A
  mfd: rtsx: using pcr_dbg replace dev_dbg

Re-format coding-style, using uniform SPC after "#define" keyword
instead of mixing using TAB and SPC.

Tabs and spaces in this context usually have different meanings
i.e. space after #define usually denotes that the following define is
a register address, whereas a tab commonly describes a bit field.

Please ensure you're not messing with these conventions.  By the looks
of it you are not, but I need you to confirm that you know what you're
doing.

if using TAB describe a bit field, and define TAB length = 8 SPC,
the editor will not show any difference(if not highlight TAB/SPC).
And the mix is not to show difference between address and field.
so all replaced by space, and show difference by next patch(02/10).

From: Micky Ching <micky_ching@realsil.com.cn>

It is more readable to place register address and values define
togather. The values define add two leading space indicate belong
to the register address defined above.

Add debug info when access register failed, this is useful for
debug.

Pull the creation of the macro into another patch.  I'm happy to apply
that, but I don't really want dbg prints scattered everywhere.  Feel
free to keep this patch on a branch and apply it when you need it, but
I'm not keen on having them in Mainline.

From: Micky Ching <micky_ching@realsil.com.cn>

update phy register value and using direct value instead of macros.
It is much easier to debug using constant value than a lot of macros.
We usually need compare the value directly to check the configure.

NACK.  This is the opposite of what I would like to see.

When we debug, we usually need to compare the value provided from hardware,
of course we can compare by print them to kernel log. but I think it more
convenient from source code. And we only set phy register when 
initialize chip,
so the value will not scattered everywhere, we will not benefit from macros.

if we want to know the meaning of setting, we can look at the register 
define.

This is not acceptable and is the complete opposite of what we're
trying to achieve.  I promote readability (by humans) as one of the
highest priorities when writing code.  0xFE6C is far from readable.

Because the truly thing we concerned is the address and value, not
a lot of macros. 0xFE6C is a magic number, but a lot of macros
even hide the magic number we curious. To verify if the source
code is right, we only need to compare the value, if too much macros
joined together, the work is boring and easy to inject errors.
I hate magic number too, but in this case using magic number
is deserved for correctness.

Two method can help enhance readability.
(1). define register address and values
If we want to know what the bit field means, we can jump to the register
define. This is very easy by tag system.
eg.
rtsx_pci_write_phy_register(pcr, PHY_BPCR, 0x05C0);
we can jump to PHY_BPCR to see bit-field define.

(2). add comment for magic number.
I don't like comment.

If you still like macro list, I will update the register next patch.

regards.
micky.

I completely disagree and think the converse to be true.  It's _much_
easier to get the magic number incorrect.

Defining register values and bit fields is the _correct_ way to do
this.  Using magic numbers is the _wrong_ way.

I'm sorry Micky, but I am not moving on this.

From: Micky Ching <micky_ching@realsil.com.cn>

To enable/disable ASPM we should find LINK CONTROL register
in PCI config space. All old chip use 0x80 address, but new
chip may use another address, so we using pci_find_capability()
to get LINK CONTROL address.

rtsx_gops.c was removed, we consider to put some common operations
to this file, but the actual thing is, only a group of chips
are in common ops1, and another group of chips in common ops2,
it is hard to decide put which ops into generic ops file.

PM_CTRL3 have been set in rts5249_optimize_phy, this function
rts5249_extra_init will be call for rts524A/rts525A, but their PM_CTRL3
address is redefined to RTS524A_PM_CTRL3, using a different address.
if we set PM_CTRL3 here, the rts524A/rts525A will also set,
but it's not a right address.

We set LCTLR to disable aspm, all old chip using 0x80 address,
but new chip will not use this address, the best way to find
this address is using pci_find_capability().

This doesn't have anything to do with adding the new chip.

And I'm not sure it's even required.

This function name is now misleading.

Please change it, or at least add a comment saying that it doesn't
only support the 5249.

I have no idea what this is doing!

You might need to change the name of some of these functions (or at
least add comments) if you plan on using them for multiple devices.

I see a couple of these now.  Why don't you make 'ops' a parameter of
*_init_params().

err value will never be positive, but I have to make it consistence

Then all of them should be changed.

I'd prefer not to live in the world of 'what if'.  I think only
checking for a less than zero error value insinuates that a greater
than zero return is acceptable, but in this case is it not.

*_init_params() is called from rtsx_pcr.c, and the ops parameter should
be static, if we make ops as a parameter, the rts524a_pcr_ops defination
should move to rtsx_pcr.c, not reasonable.ÿôèº{.nÇ+‰·Ÿ®‰†+%ŠËÿ±éÝ¶\x17¥Šwÿº{.nÇ+‰·¥Š{±þG«éÿŠ{ayº\x1dÊ‡Ú™ë,j\a¢f£¢·hšïêÿ‘êçz_è®\x03(éšŽŠÝ¢j"ú\x1a¶^[m§ÿÿ¾\a«þG«éÿ¢¸?™¨èÚ&£ø§~á¶iO•æ¬z·švØ^\x14\x04\x1a¶^[m§ÿÿÃ\fÿ¶ìÿ¢¸?–I¥

Shouldn't these be defined somewhere?

I have a particular distaste for magic numbers.

Small formatting nit: I'd prefer if you'd line up the wrap to the '('
and leave a '\n' before the return line.

This might look nicer as a switch().

rtsx_pci_write_register() can't return >0, so just check for (err).

More magic numbers that I have absolutely no idea what the mean.

Please define them (includes the one below).

This is the chip ID number, no need define, just using it.
if we define, it will like RTS525A_PCI_ID, so bad.ÿôèº{.nÇ+‰·Ÿ®‰†+%ŠËÿ±éÝ¶\x17¥Šwÿº{.nÇ+‰·¥Š{±þG«éÿŠ{ayº\x1dÊ‡Ú™ë,j\a¢f£¢·hšïêÿ‘êçz_è®\x03(éšŽŠÝ¢j"ú\x1a¶^[m§ÿÿ¾\a«þG«éÿ¢¸?™¨èÚ&£ø§~á¶iO•æ¬z·švØ^\x14\x04\x1a¶^[m§ÿÿÃ\fÿ¶ìÿ¢¸?–I¥
