pinctrl: imx8mq: Add suspend/resume ops

2019-04-11T13:41:43+00:00

To support pinctl hog restore after LPSR resume back,
add the generic suspend/resume in pinctrl-imx along with the
generic pm ops to be used by platform specific drivers. Then
make use of the newly added ops in i.MX8MQ platform specific
driver.

pinctrl: freescale: use devm_platform_ioremap_resource() to simplify code

2019-04-08T11:41:03+00:00

Use the new helper devm_platform_ioremap_resource() which wraps the
platform_get_resource() and devm_ioremap_resource() together, to
simplify the code.

pinctrl: imx: remove an unnecessary NULL check

2019-04-08T11:06:30+00:00

The address of "ipctl->pin_regs[pin_id]" can't be NULL.  It's the offset
into an array in the middle of a struct.  This patch removes the check.

pinctrl: imx: fix scu link errors

2019-03-08T12:17:24+00:00

Currently PINCTRL_IMX8QM and PINCTRL_IMX8QXP will select PINCTRL_IMX_SCU.
However, PINCTRL_IMX_SCU may not be valid due to it depends on IMX_MBOX.
Then we may meet the following link errors:

Rework so that PINCTRL_IMX8QM and PINCTRL_IMX8QXP depends on IMX_SCU
as well in case they're wrongly enabled.

pinctrl: imx: add imx8qm driver

2019-01-11T08:25:01+00:00

MX8QM 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 MX8QM pinctrl driver.
