Several adaptions: * Rename stm32mp157c-bytedevkit-common.dtsi to stm32mp157c-bytedevkit.dtsi * Merge everything from stm32mp157c-bytedevkit-v1-1.dts into stm32mp157c-bytedevkit.dtsi * Rename some pinctrls and use predefined * Adapt similar to stm32mp157c-dk2.dts Open issues: * Ethernet is set to 100Mb, as 1Gb is not reliable * USB OTG is fixed to peripheral; HW needs to be checked

Link pwm_stm32 and stm32_timers statically. Using them as modules means that they will be loaded too late and that the boot logo can't be shown because pwm-backlight can't control the pwm yet.

…ATE_QUEUED [ Upstream commit fbe04b4 ] If the callback 'start_streaming' fails, then all queued buffers in the driver should be returned with state 'VB2_BUF_STATE_QUEUED'. Currently, they are returned with 'VB2_BUF_STATE_ERROR' which is wrong. Fix this.

In iavf_shutdown() the adapter state is changed to __IAVF_REMOVE. In ice_shutdown() the call chain above is executed, which at some point calls iavf_remove(). However iavf_remove() expects the VF to be in one of the states __IAVF_RUNNING, __IAVF_DOWN or __IAVF_INIT_FAILED. If that's not the case it sleeps forever. So if iavf_shutdown() gets invoked before iavf_remove() the system will hang indefinitely because the adapter is already in state __IAVF_REMOVE. Fix this by returning from iavf_remove() if the state is __IAVF_REMOVE, as we already went through iavf_shutdown().
