x86: pinctrl: Silence the warning when a pin is not found

2020-11-06T01:51:33Z

This does not necessarily indicate a problem, since some pins are optional. Let the caller show an error if necessary. Reviewed-by: Bin Meng Signed-off-by: Simon Glass

x86: Fix up driver names to avoid dtoc warnings

pinctrl: Add support for Kendryte K210 FPIOA

2020-10-08T15:42:36Z

The Fully-Programmable Input/Output Array (FPIOA) device controls pin multiplexing on the K210. The FPIOA can remap any supported function to any multifunctional IO pin. It can also perform basic GPIO functions, such as reading the current value of a pin. However, GPIO functionality remains largely unimplemented (in favor of the dedicated GPIO peripherals).

test: pinmux: Add test for pin muxing

2020-10-08T15:42:36Z

This extends the pinctrl-sandbox driver to support pin muxing, and adds a test for that behaviour. The test is done in C and not python (like the existing tests for the pinctrl uclass) because it needs to call pinctrl_select_state. Another option could be to add a command that invokes pinctrl_select_state and then test everything in test/py/tests/test_pinmux.py. The pinctrl-sandbox driver now mimics the way that many pinmux devices work. There are two groups of pins which are muxed together, as well as four pins which are muxed individually. I have tried to test all normal paths. However, very few error cases are explicitly checked for. Signed-off-by: Sean Anderson Reviewed-by: Simon Glass

pinctrl: Add pinmux property support to pinctrl-generic

2020-10-08T15:42:36Z

The pinmux property allows for smaller and more compact device trees, especially when there are many pins which need to be assigned individually. Instead of specifying an array of strings to be parsed as pins and a function property, the pinmux property contains an array of integers representing pinmux groups. A pinmux group consists of the pin identifier and mux settings represented as a single integer or an array of integers. Each individual pin controller driver specifies the exact format of a pinmux group. As specified in the Linux documentation, a pinmux group may be multiple integers long. However, no existing drivers use multi-integer pinmux groups, so I have chosen to omit this feature. This makes the implementation easier, since there is no need to allocate a buffer to do endian conversions. Support for the pinmux property is done differently than in Linux. As far as I can tell, inversion of control is used when implementing support for the pins and groups properties to avoid allocating. This results in some duplication of effort; every property in a config node is parsed once for each pin in that node. This is not such an overhead with pins and groups properties, since having multiple pins in one config node does not occur especially often. However, the semantics of the pinmux property make such a configuration much more appealing. A future patch could parse all config properties at once and store them in an array. This would make it easier to create drivers which do not function solely as callbacks from pinctrl-generic. This commit increases the size of the sandbox build by approximately 48 bytes. However, it also decreases the size of the K210 device tree by 2 KiB from the previous version of this series. The documentation has been updated from the last Linux commit before it was split off into yaml files. Signed-off-by: Sean Anderson Reviewed-by: Simon Glass
