pinctrl: freescale: Break dependency on SOC_IMX8MQ for i.MX8MQ

2018-12-27T09:39:27+00:00

The CONFIG_SOC_IMX8MQ will go away, so the dependency can be based on
ARCH_MXC && ARM64.

pinctrl: imx8qxp: break the dependency on SOC_IMX8QXP

2018-12-21T10:23:18+00:00

ARM64 SoC does not encourage people to add more finegrained SoC
config options rather than a single ARCH_ in arch Kconfig.
So this patch aims to break the dependency on SOC_IMX8QXP.

pinctrl: imx: fix NO_PAD_CTL setting for MMIO pads

2018-11-19T13:51:42+00:00

After patch b96eea718bf6 ("pinctrl: fsl: add scu based pinctrl support"),
NO_PAD_CTL pads map are not skipped anymore which results in
a possible memory corruption. As we actually only need to create config
maps for SCU pads and MMIO pads which are not using the default config
(a.k.a IMX_NO_PAD_CTL), so let's add a proper check before creating
the config maps. And during MMIO pads parsing, we also need update the
list_p point as SCU case to ensure the pin data next parsed is correct.

pinctrl: fsl: imx7ulp: change to use imx legacy binding

2018-11-09T09:54:29+00:00

We already had an earlier conclusion that all new i.MX Socs will keep
using the legacy i.MX Pinctrl bindings instead of generic pin config.
However, MX7ULP generic pin config binding support has already been in
tree before that time. Per SoC maintainers' suggestions, in order to
get a better consistency for all i.MX devices, we'd like to go back to
imx legacy binding for MX7ULP as well.

pinctrl: imx: add imx8qxp driver

2018-11-05T08:33:32+00:00

MX8QXP contains a system controller that is responsible for controlling
the pad setting of the IPs that are present. Communication between the
host processor running an OS and the system controller happens through
a SCU protocol. This patch adds the SCU based MX8QXP pinctrl driver.

pinctrl: fsl: add scu based pinctrl support

2018-11-05T08:33:32+00:00

Some i.MX SoCs (e.g. MX8QXP and MX8QM) contain a system controller
that is responsible for controlling the pad setting of the IPs that
are present. Communication between the host processor running an OS
and the system controller happens through a SCU protocol.

This patch classifies the pad settings into two categories: MMIO and SCU.
For the original MMIO method, no functional changes except organize them
into a few imx_*_mmio() functions. Besides that, we add the SCU based
Pad Mux and Pinconf setting support which are implemented in pinctrl-scu.c.

pinctrl: mxs: do not export mxs_pinctrl_probe

2018-09-20T22:45:14+00:00

No user of mxs_pinctrl_probe() can be built as a module, hence
exporting the symbol is not necessary. Drop EXPORT_SYMBOL_GPL.

Inspired by a patch from Stefan Agner for the tegra pinctrl driver.

pinctrl: freescale: off by one in imx1_pinconf_group_dbg_show()

The info->groups[] array is allocated in imx1_pinctrl_parse_dt().  It
has info->ngroups elements.  Thus the > here should be >= to prevent
reading one element beyond the end of the array.
