pinctrl: tegra: Display pin function in pinconf-groups

2023-11-13T13:57:22Z

The function that a pin is muxed to can be read from the top-level pinctrl-maps debugfs file. However, this only reflects the values that were specified in device tree, so they will only show deviations from the hardware default setting. Display the current pinmux setting in the per-controller pinconf-groups debugfs file along with the rest of the per-pin configuration settings.

pinctrl: tegra: add OF node when logging OF parsing errors

2023-09-27T08:54:59Z

These errors are not quite clear without also logging they device tree node being parsed, especially when the pinmux node has lots of subnodes. Adding the node name helps a lot in finding the node that triggers the error.

This reverts commit d1cd5b51bc9152dc2b63c5f843590272d6694d50. It was reported that some I2C3 functions stop working after this patch, and it is just debug help so let's revert it and investigate. Link: https://lore.kernel.org/linux-gpio/20230925183049.10a40546@booty/ Signed-off-by: Linus Walleij

pinctrl: tegra: Switch to use DEFINE_NOIRQ_DEV_PM_OPS() helper

2023-08-21T16:07:44Z

Since pm.h provides a helper for system no-IRQ PM callbacks, switch the driver to use it instead of open coded variant. With that, make sure the PM ops are used only in CONFIG_PM_SLEEP=y case by wrapping them in pm_sleep_ptr() macro.

pinctrl: Explicitly include correct DT includes

2023-07-20T19:41:24Z

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

pinctrl: tegra: avoid duplicate field initializers

2023-06-19T08:54:35Z

The drv_reg field is initialized both in the DRV_PINGROUP_ENTRY_N/DRV_PINGROUP_ENTRY_Y macros and in DRV_PINGROUP_Y. Since each pingroup expands both macros, the are always duplicate and turning on -Woverride-init (which is disabled by default) causes a huge amount of warnings like: drivers/pinctrl/tegra/pinctrl-tegra234.c:1384:27: error: initialized field overwritten [-Werror=override-init] 1384 | #define DRV_PINGROUP_Y(r) ((r)) | ^ drivers/pinctrl/tegra/pinctrl-tegra234.c:1397:28: note: in expansion of macro 'DRV_PINGROUP_Y' 1397 | .drv_reg = DRV_PINGROUP_Y(r), \ | ^~~~~~~~~~~~~~ drivers/pinctrl/tegra/pinctrl-tegra234.c:1447:49: note: in expansion of macro 'DRV_PINGROUP_ENTRY_Y' 1447 | #define drive_soc_gpio08_pb0 DRV_PINGROUP_ENTRY_Y(0x500c, 12, 5, 20, 5, -1, -1, -1, -1, 0) | ^~~~~~~~~~~~~~~~~~~~ ...
