After commit 34e61801 "pinctrl: meson-gxbb: Add missing GPIODV_18 pin entry" I started to get the following warning: "meson-pinctrl c8834000.periphs:pinctrl@4b0: names 119 do not match number of GPIOs 120" It turned out that not the mentioned commit has a problem, it just revealed another problem which had existed before. There is no PIN GPIOX_22 on Meson GXBB.

With "SPI_MASTER=y && I2C=m", we can build mcp23s08 as a built-in driver, which then results in a link failure: drivers/pinctrl/built-in.o: In function `mcp23s08_probe_one.isra.0': :(.text+0x7910): undefined reference to `__devm_regmap_init_i2c' drivers/pinctrl/built-in.o: In function `mcp23s08_init': :(.init.text+0x110): undefined reference to `i2c_register_driver' drivers/pinctrl/built-in.o: In function `mcp23s08_exit': :(.exit.text+0x3c): undefined reference to `i2c_del_driver' To avoid the problem, this adds another dependency on I2C that enforces mcp23s08 to be a loadable module whenever the I2C core is a module.

David Wu authored
On the some rockchip SOCS, some things like rk3399 specific uart2 can use multiple pins. Somewhere between the pin io-cells and the uart it seems to have some sort of switch to decide to which pin to actually route the data. +-------+ +--------+ /- GPIO4_B0 (pinmux 2) | uart2 | -- | switch | --- GPIO4_C0 (pinmux 2) +-------+ +--------+ \- GPIO4_C3 (pinmux 2) (switch selects one of the 3 pins base on the GRF_SOC_CON7[BIT0, BIT1]) The routing switch is determined by one pin of a specific group to be set to its special pinmux function. If the pinmux setting is wrong for that pin the ip block won't work correctly anyway.

Fixups here tend to be more of a conglomerate of some of the other repeated/systematic ones we've seen in the earlier pinctrl cleanups. We remove module.h from code that isn't doing anything modular at all; if they have __init sections, then replace it with init.h One driver has a .remove that would be dispatched on module_exit, and as that code is essentially orphaned, so we remove it. In case anyone was previously doing the (pointless) unbind to get to that function, we disable unbind for this one driver as well. A couple bool drivers (hence non-modular) are converted over to to builtin_platform_driver(). Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.

None of the Kconfigs for any of these drivers are tristate, meaning that they currently are not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the drivers there is no doubt they are builtin-only. All drivers get similar changes, so they are handled in batch. We remove module.h from code that isn't doing anything modular at all; if they have __init sections, then replace it with init.h. A couple drivers have module_exit() code that is essentially orphaned, and so we remove that. Quite a few bool drivers (hence non-modular) are converted over to to builtin_platform_driver(). Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit.

This moves irq property handling from spi/i2c specific code into the generic mcp23s08_probe_one. This is possible because the device properties are named equally. As a side-effect this drops support for setting the properties via pdata, which has no mainline users. If boardcode wants to enable the chip as interrupt controller it can attach the device properties instead.
