We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

It depends on the board implementation whether to have each pins of CTS/RTS, and others for modem. So it is necessary to divide current uart_ctsrts group into uart_ctsrts and uart_modem groups. Since the number of implemented pins for modem differs depending on SoC, each uart_modem group also has a different number of pins. Signed-off-by:

The AST2600 pinmux is fairly similar to the previous generations of ASPEED BMC SoCs in terms of architecture, though differ in some of the design details. The complexity of the pin expressions is largely reduced (e.g. there are no-longer signals with multiple expressions muxing them to the associated pin), and there are now signals and buses with multiple pin groups. The driver implements pinmux support for all 244 GPIO-capable pins plus a further four pins that are not GPIO capable but which expose multiple signals. pinconf will be implemented in a follow-up patch. The implementation has been smoke-tested under qemu, and run on hardware by ASPEED. Debugged-by:

The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match. Signed-off-by:

Rename macros as follows: * s/SS_PIN_DECL()/PIN_DECL_1()/ * s/MS_PIN_DECL()/PIN_DECL_2()/ * s/MS_PIN_DECL_()/PIN_DECL_()/ This is in preparation for adding PIN_DECL_3(). We could clean this up with e.g. CPPMAGIC_MAP() from ccan, but that might be a bridge too far given how much of a macro jungle we already have. Signed-off-by:

The BCM2711 has a new way of selecting the pull-up/pull-down setting for a GPIO pin. The registers used for the BCM2835, GP_PUD and GP_PUDCLKn0, are no longer connected. A new set of registers, GP_GPIO_PUP_PDN_CNTRL_REGx must be used. This commit will add a new compatible string "brcm,bcm2711-gpio" and the kernel driver will use it to select which method is used to select pull-up/pull-down. This patch based on a patch by Al Cooper which was intended for the BCM7211. This is a bugfixed and improved version. Signed-off-by:
