2021-01-29ARM: dts: stm32: add #clock-cells property to usbphyc node on stm32mp151Amelie Delaunay
usbphyc is a 48Mhz clock provider: the clock can be used as clock source for USB OTG. Add #clock-cells property to usbphyc node to reflect this capability. Signed-off-by: Amelie Delaunay <amelie.delaunay@foss.st.com> Signed-off-by: Alexandre Torgue <alexandre.torgue@foss.st.com>

2020-11-26ARM: dts: stm32: support child mfd cells for the stm32mp1 TAMP sysconAhmad Fatoum
The stm32mp1 TAMP peripheral has 32 backup registers that survive a warm reset. This makes them suitable for storing a reboot mode, which the vendor's kernel tree is already doing[0]. The actual syscon-reboot-mode child node can be added by a board.dts or fixed up by the bootloader. For the child node to be probed, the compatible needs to include simple-mfd. The binding now specifies this, so have the SoC dtsi adhere to it.

2020-11-26ARM: dts: stm32: update stm32mp151 for remote proc synchronization supportArnaud Pouliquen
Two backup registers are used to store the Cortex-M4 state and the resource table address. Declare the tamp node and add associated properties in m4_rproc node to allow Linux to attach to a firmware loaded by the first boot stages. Associated driver implementation is available in commit 9276536f455b3 ("remoteproc: stm32: Parse syscon that will manage M4 synchronisation").
