Fix codying style broken by recent libfdt sync

2016-10-24T12:04:42+00:00

Commit b02e4044ff8e ("libfdt: Bring in upstream stringlist
functions") broke codying style in some places especially
by inserting an extra whitespace before fdt_stringlist_count().

pinctrl: uniphier: fix unused-const-variable warnings for GCC 6.x

2016-10-18T05:06:46+00:00

Marek reports warnings in UniPhier pinctrl drivers when compiled by
GCC 6.x, like:

  drivers/pinctrl/uniphier/pinctrl-uniphier-ld20.c:58:18: warning:
  'usb3_muxvals' defined but not used [-Wunused-const-variable=]
   static const int usb3_muxvals[] = {0, 0};
                    ^~~~~~~~~~~~

My intention here is to compile minimum set of pin data for SPL to
save memory footprint, but GCC these days is clever enough to notice
unused data arrays.

We can fix it by sprinkling around __maybe_unused on those arrays,
but I did not do that because they are counterparts of the pinctrl
drivers in Linux.  All the pin data were just copy-pasted from Linux
and are kept in sync for maintainability.

I chose a bit tricky way to fix the issue; calculate ARRAY_SIZE of
*_pins and *_muxvals and set their sum to an unused struct member.
This trick will satisfy GCC because the data arrays are used anyway,
but such data arrays will be dropped from the final binary because
the pointers to them are not used.

libfdt: Bring in upstream stringlist functions

2016-10-13T19:54:10+00:00

These have now landed upstream. The naming is different and in one case the
function signature has changed. Update the code to match.

This applies the following upstream commits by
Thierry Reding  :

   604e61e fdt: Add functions to retrieve strings
   8702bd1 fdt: Add a function to get the index of a string
   2218387 fdt: Add a function to count strings

pinctrl: imx: do not announce driver initialization

2016-10-07T10:26:14+00:00

It is not usual that drivers announce when they have been initialized.
use dev_dbg to announce device initialization.

pinctrl: imx6: support i.MX6ULL

2016-10-04T13:41:01+00:00

There two iomuxc for i.MX6ULL. one iomuxc is compatible is i.MX6UL,
the other iomuxc is for SVNS usage, similar with the one in mx7.

pinctrl: uniphier: support 4bit-width pin-mux register capability

2016-09-18T14:10:11+00:00

On LD4 SoC or later, the pin-mux registers are 8bit wide, while 4bit
wide on sLD3 SoC.  Support it for the sLD3 pinctrl driver.

pinctrl: uniphier: move register base macros from header to .c file

2016-09-14T13:54:19+00:00

These macros are only referenced in pinctrl-uniphier-core.c, so
they need not reside in a header file.
