dae5597f25 pinctrl: mvebu: armada-{370,375,38x,39x,xp}: normalize TDM pins
This commit normalizes the naming of the TDM pins accross the
different Marvell SoCs. Mainly it consists in:

 * Removing the 'n' from signal names: 'intn' becomes 'int' and 'rstn'
   becomes 'rst'

 * Renaming the main name 'tdm2c' to 'tdm' on Armada 38x.

 * Change the main name 'tdm-1' to 'tdm' for one of the pins of the
   Armada XP

The last two changes affect DT compatibility, but since the TDM
interface is nowhere near being supported in mainline, it should not
be considered to be a serious problem at this point.

7bd6a26db6 pinctrl: mvebu: armada-{370,375,38x,39x}: normalize dev pins
This commit modifies the definition of the Device Bus interface pins
to be consistent accross SoCs. Especially, it removes the 'n'
indicators that we don't encode in the subnames of pins:

   'dev(wen0)' becomes 'dev(we0)'
   'dev(wen1)' becomes 'dev(we1)'
   'dev(oen)' becomes 'dev(oe)'
   etc.

In addition, it fixes the Armada 375 DT binding documentation, which
forgot to document the 'dev' function for MPP46, MPP57 and MPP63.

Since only the subnames are changed, this commit does not affect DT
compatibility.

100dc5d840 pinctrl: mvebu: armada-{38x,39x,xp}: normalize naming of DRAM functions
This commit makes the dram functions naming (both the name and
subname) consistent accross SoC, by using:

  dram(vttctrl)
  dram(deccerr)

in all Marvell SoCs.

Due to the change to the name, it changes the DT binding, but these
functions are not used by any in-tree Device Tree file, and are very
unlikely to be used by anyone.

9540cf5344 pinctrl: mvebu: armada-{375,38x,39x}: normalize naming of PTP subnames
The subnames are purely informative, but it's nicer when they match
accross SoCs. This commit adjusts the Armada 375, Armada 38x and
Armada 39x MPP definitions so that the subnames of the PTP pins match
the ones used on Armada XP and Kirkwood.

27e7cd0165 pinctrl: mvebu: armada-38x: fix incorrect total number of GPIOs
The pinctrl_gpio_range[] array described a first bank of 32 GPIOs and
a second one of 27 GPIOs. However, since there is a total of 60 MPP
pins that can be muxed as GPIOs, the second bank really has 28 GPIOs.

331642fbf2 pinctrl: mvebu: armada-38x: fix PCIe functions
A new revision of the Marvell Armada 38x hardware datasheet unveiled
that the definition of some of the PCIe functions were not
correct. This commit fixes the pinctrl driver accordingly.

Some PCIe functions simply do not exist, some of the PCIe functions in
fact were corresponding to other functions, and some PCIe functions
have been added.

Note: the seemingly unrelated removal of spi(cs2) on MPP47 is related:
this function is in fact implemented on MPP43, instead of a PCIe
function.

ca6d9a084b pinctrl: mvebu: add pin-muxing driver for the Marvell Armada 380/385
The Marvell Armada 380/385 are new ARM SoCs from Marvell, part of the
mvebu family, but using a Cortex-A9 CPU core. In terms of pin-muxing,
it is similar to Armada 370 and XP for the register layout, only
different in the number of available pins and their
functions. Therefore, we simply use the existing
drivers/pinctrl/mvebu/ infrastructure, with no other changes that the
list of pins and corresponding functions.
