2eda1cde - pinctrl: aspeed: Add AST2600 pinmux support

Thu, 11 Jul 2019 04:19:42 +0000

pinctrl: aspeed: Add AST2600 pinmux supportThe AST2600 pinmux is fairly similar to the previous generations ofASPEED BMC SoCs in terms of architecture, though differ in some of thedesign details. The complexity of the pin expressions is largely reduced(e.g. there are no-longer signals with multiple expressions muxing themto the associated pin), and there are now signals and buses withmultiple pin groups.The driver implements pinmux support for all 244 GPIO-capable pins plusa further four pins that are not GPIO capable but which expose multiplesignals. pinconf will be implemented in a follow-up patch.The implementation has been smoke-tested under qemu, and run on hardwareby ASPEED.Debugged-by: Johnny Huang Signed-off-by: Andrew Jeffery Link: https://lore.kernel.org/r/20190711041942.23202-7-andrew@aj.id.auSigned-off-by: Linus Walleij List of files: /linux-6.15/drivers/pinctrl/aspeed/Kconfig

4d3d0e42 - pinctrl: Add core support for Aspeed SoCs

Tue, 30 Aug 2016 07:54:24 +0000

pinctrl: Add core support for Aspeed SoCsThe Aspeed SoCs typically provide more than 200 pins for GPIO and otherfunctions. The signal enabled on a pin is determined on a prioritybasis, where a given pin can provide a number of different signal types.In addition to the priority levels, the Aspeed pin controllers describethe signal active on a pin by compound logical expressions involvingmultiple operators, registers and bits. Some difficulty arises as apin's function bit masks for each priority level are frequently not thesame (i.e. we cannot just flip a bit to change from a high to lowpriority signal), or even in the same register(s). Some configurationbits affect multiple pins, while in other cases the signals for a busmust each be enabled individually.Together, these features give rise to some complexity in theimplementation. A more complete description of the complexities isprovided in the associated header file.The patch doesn't implement pinctrl/pinmux/pinconf for any particularAspeed SoC, rather it adds the framework for defining pinmuxconfigurations.Signed-off-by: Andrew Jeffery Reviewed-by: Joel Stanley Signed-off-by: Linus Walleij List of files: /linux-6.15/drivers/pinctrl/aspeed/Kconfig
