Revert "pinctrl: freescale: imx: Use 'devm_of_iomap()' to avoid a resource leak in case of error in 'imx_pinctrl_probe()'"

2020-06-20T20:04:39+00:00

This reverts commit ba403242615c2c99e27af7984b1650771a2cc2c9.

After commit 26d8cde5260b ("pinctrl: freescale: imx: add shared
input select reg support"). i.MX7D has two iomux controllers
iomuxc and iomuxc-lpsr which share select_input register for
daisy chain settings.
If use 'devm_of_iomap()', when probe the iomuxc-lpsr, will call
devm_request_mem_region() for the region <0x30330000-0x3033ffff>
for the first time. Then, next time when probe the iomuxc, API
devm_platform_ioremap_resource() will also use the API
devm_request_mem_region() for the share region <0x30330000-0x3033ffff>
again, then cause issue, log like below:

[    0.179561] imx7d-pinctrl 302c0000.iomuxc-lpsr: initialized IMX pinctrl driver
[    0.191742] imx7d-pinctrl 30330000.pinctrl: can't request region for resource [mem 0x30330000-0x3033ffff]
[    0.191842] imx7d-pinctrl: probe of 30330000.pinctrl failed with error -16

pinctrl: freescale: imx: Use 'devm_of_iomap()' to avoid a resource leak in case of error in 'imx_pinctrl_probe()'

2020-06-03T12:35:41+00:00

Use 'devm_of_iomap()' instead 'of_iomap()' to avoid a resource leak in
case of error.

Update the error handling code accordingly.

pinctrl: freescale: imx: Fix an error handling path in 'imx_pinctrl_probe()'

2020-06-03T12:34:21+00:00

'pinctrl_unregister()' should not be called to undo
'devm_pinctrl_register_and_init()', it is already handled by the framework.

This simplifies the error handling paths of the probe function.
The 'imx_free_resources()' can be removed as well.

pinctrl: imx: Add imx8dxl driver

2020-04-16T12:21:22+00:00

i.MX8DXL 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, add support for the SCU based i.MX8DXL pinctrl driver.

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v5.7 kernel cycle.

There are no core changes this time, only driver developments:

- New driver for the Dialog Semiconductor DA9062 Power Management
Integrated Circuit (PMIC).

- Renesas SH-PFC has improved consistency, with group and register
checks in the configuration checker.

- New subdriver for the Qualcomm IPQ6018.

- Add the RGMII pin control functionality to Qualcomm IPQ8064.

- Performance and code quality cleanups in the Mediatek driver.

- Improve the Broadcom BCM2835 support to cover all the GPIOs that
exist in it.

- The Allwinner/Sunxi driver properly masks non-wakeup IRQs on
suspend.

- Add some missing groups and functions to the Ingenic driver.

- Convert some of the Freescale device tree bindings to use the new
and all improved JSON YAML markup.

- Refactorings and support for the SFIO/GPIO in the Tegra194 SoC
driver.

- Support high impedance mode in the Spreadtrum/Unisoc driver"

the dependency on ARM64 to make the driver could be selected for
ARM32.

pinctrl: imx: scu: Align imx sc msg structs to 4

2020-02-21T15:33:27+00:00

The imx SC api strongly assumes that messages are composed out of
4-bytes words but some of our message structs have odd sizeofs.

This produces many oopses with CONFIG_KASAN=y.

Fix by marking with __aligned(4).

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes, nothing too exciting about
this.

Some changes hit arch/sh and arch/arm but are well isolated and
acknowledged by the respective arch maintainers.

Core changes:

- Dropped the chained IRQ setup callback into GPIOLIB as we got rid
of the last users of that in this changeset.

New drivers:

- New driver for Ingenic X1830.

- New driver for Freescale i.MX8MP.

Driver enhancements:

- Fix all remaining Intel drivers to pass their IRQ chips along with
the GPIO chips.

- Intel Baytrail allocates its irqchip dynamically.

- Intel Lynxpoint is thoroughly rewritten and modernized.

- Aspeed AST2600 pin muxing and configuration is much improved.

- Qualcomm SC7180 functions are updated and wakeup interrupt map is
provided.

- A whole slew of Renesas SH-PFC cleanups and improvements.

- Fix up the Intel DT bindings to use the generic YAML DT bindings
schema (a first user of this)"
