Pinctrl and Pinmux — Das U-Boot unknown version documentation

WebThis protocol is part of the feature that was designed to separate the pinctrl subsystem from the SCP firmware. The idea is to separate communication of the pin control subsystem with the hardware to SCP firmware (or a similar system, such as ATF), which provides an interface to give the OS ability to control the hardware through SCMI protocol. WebTo specify the pinmux setting in the board-specific dts file, both Linux and u-boot has a Pinctrl subsystem. This pinctrl API can be used to set the pinmux setting of each pin. … Webpinctrl core: initialized pinctrl subsystem random: fast init done NET: Registered protocol family 16 DMA: preallocated 256 KiB pool for atomic coherent allocations cpuidle: using … cunybuy marketplace
