This patch adds a new logic inside the st pinctrl to manage
an unsupported scenario: some sysconfig are not available!
This is the case of STiH407 where, although documented, the
following registers from SYSCFG_FLASH have been removed from the SoC.
SYSTEM_CONFIG3040
Output Enable pad control for all PIO Alternate Functions
and
SYSTEM_ CONFIG3050
Pull Up pad control for all PIO Alternate Functions
Without managing this condition an imprecise external abort
will be detect.
To do this the patch also reviews the st_parse_syscfgs
and other routines to manipulate the registers only if
actually available.
In any case, for example the st_parse_syscfgs detected
an error condition but no action was made in the
st_pctl_probe_dt.

Hm this does not apply to my tree at all. It appears this is not
a stand-alone, patch, so it depends on some other patch to
pinctrl-sti?

Yes, it depends on patch 2 of the series (which is based on v3.14-rc4).
This is my mistake, the title of patch 2 is wrong:
ARM: STi: add pinctrl support for the STiH407 SoC
Should be:
pinctrl: st: add pinctrl support for the STiH407 SoC
I will resend the pinctrl patches rebased on your tree.

B2120 HDK is the reference board for STiH407 SoC.
It has the following characteristics:
- 1GB DDR3
- 8GB eMMC / SD-Card slot
- 32MB NOR Flash
- 1 x Gbit Ethernet
- 1 x USB 3.0 port
- 1 x Mini-PCIe
- 1 x SATA
- 1 x HDMI output
- 1 x HDMI input
- 1 x SPDIF
This patch only introduces basic functionnalities, such as I2C and UART.

So I'd like to take the pinctrl patch through my tree and the rest through
ARM SoC but it seems it does not apply :-/

Sorry, the series was based on v3.14-rc4.
I split the series in two:
- pinctrl patches based on the linux-pinctrl/devel branch
- ARM patches on arm_soc
