44510daea4 dm: pinctrl: fix for introduce PINCONF_RECURSIVE option
Correct the name of the define used CONFIG_IS_ENABLED which is
not aligned with Kconfig name: CONFIG_$(SPL_)PINCONF_RECURSIVE.

The recursive calls is conditional only for UCLASS_PINCONFIG
"pinconfig" driver.
It is always needed to call pinctrl_post_bind for UCLASS_PINCTRL
"pinctrl", the test CONFIG_IS_ENABLED(PINCONF_RECURSIVE) need to
be removed for this driver.

This correct a regression introduced because the same patch is
applied twice times in u-boot-dm branch:
- commit e878b53a79 ("dm: pinctrl: introduce PINCONF_RECURSIVE
  option")
- commit c20851b3d8 ("dm: pinctrl: introduce PINCONF_RECURSIVE

e878b53a79 dm: pinctrl: introduce PINCONF_RECURSIVE option
In the Linux pinctrl binding, the pin configuration nodes don't need to
be direct children of the pin controller device (may be grandchildren for
example). This behavior is managed with the pinconfig u-class which
recursively bind all the sub-node of the pin controller.

But for some binding (when pin configuration is only children of pin
controller) that is not necessary. U-Boot can save memory and reduce
the number of pinconf instance when this feature is deactivated
(for arch stm32mp for example for SPL).

This patch allows to control this feature with a new option
CONFIG_PINCONF_RECURSIVE when it is possible for each individual
pin controller device.

c115cd154c pinctrl: nxp: DM_FLAG_PRE_RELOC by default
For NXP SoCs we have to set pinmux configuration ASAP (ideally
before relocation) to get serial console working. Without this we miss
almost the half of output (U-boot version, CPU defails, Reset cause,
DRAM details etc.).

To achieve this we need to force appropriate pinctrl drivers to get
probed before relocation.

abee80d789 pinctrl: stmfx: update pinconf settings
Alignment with kernel driver.

According to the following tab (coming from STMFX datasheet), updates
have to done in stmfx_pinctrl_conf_set function:

-"type" has to be set when "bias" is configured as "pull-up or pull-down"
-PIN_CONFIG_DRIVE_PUSH_PULL should only be used when gpio is configured as
 output. There is so no need to check direction.

7f2e60f1ba pinctrl: renesas: Synchronize Gen2/Gen3 tables with Linux 5.2
In spite of the summary line, U-Boot commits [1-2] seem to have
aligned the U-Boot PFC tables to Linux v5.1 rather than to v5.0, since
they also imported the Linux 5.1 commits listed in [3].

What current commit tries to accomplish is to align the Gen2 and Gen3
pinctrl tables to Linux v5.2. Importing these updates in two steps
as done before (i.e. separately for Gen2 and Gen3) is somewhat difficult
due to Linux commits like [5-6] which atomically update both Gen2/3
platforms and whose breakdown would not be easily possible.

The detailed list of Linux commits squashed into this U-Boot patch is
shown in [4]. The second column in [4] depicts the patch id mismatch
between the original Linux and the resulted U-Boot commit. The
exclamation mark means that manual conflict resolution was involved
during cherry picking Linux commit into U-Boot repository (this is
mainly caused by dropped changes in files like pfc-r8a7795-es1.c and
pfc-r8a77980.c which are missing in U-Boot).

This patch has been applied on top of v2019.07-rc4-155-g8754656680b6 and
boot-tested on:
 - H3-ES2.0-Salvator-X
 - M3-ES1.1-Salvator-XS

0f66653310 pinctrl: mxs: Add support for i.MX2[38] mxs pinctrl driver
The code responsible for setting proper values in the MUX registers
(in the mxs_pinctrl_set_state()) has been ported from Linux kernel
- SHA1: 17bb763e7eaf tag v5.1.11 from linux-stable.

As the pinctrl node in the imx28.dtsi file has gpio pins nodes as subnodes,
it was necessary to use 'dm_scan_fdt_dev()' (as a .bind method) to also
make them 'visible' by the DM's "gpio_mxs" driver.

b9308f2c05 pinctrl: meson-axg: add support for getting pinmux status
In order to support the "pinmux status" command, use the common functions
to get the pins count and names, and add the AXG specific function to get
the current function from registers.

The GPIO_TEST_N was in the wrong pmx group table, move it back with the AO
groups, GPIODV_18 was missing, add it back, and finally the GPIOCLK_*

c0df121a97 pinctrl: imx: Define imx6_pinctrl_soc_info in .data section
This commit is necessary to be able to re-use the pinctrl code in early
SPL to properly configure pins.

The problem is that those "static" structures (without explicit
initialization) are placed in the SDRAM area, which corresponds to
u-boot proper (not even SPL).
Hence, when one wants to configure pins before relocation via DTS/DM,
the board hangs (imx6q SoC powered one) as only OCRAM area is available
(0x009xxxxx).

This commit prevents from this issue by moving the imx6_pinctrl_soc_info
structure to data section (from BSS).
