Update Patrick and my email address with the one dedicated to upstream activities.

| * arm: stm32mp: stm32prog: always flush DFU on start command for uartPatrick Delaunay2021-01-131-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the test on data->dfu_seq, because dfu_seq=0 not only when the DFU is not started (mask with 0xffff). This flush is mandatory as the final treatment, common with USB, is done in DFU callback. This patch avoids issue if the received length is a multiple of the DFU packet. For example if size of bootfs partition is egual to 0x4000000, data->dfu_seq=0 at the end of the partition, the flush it not requested and the phase is not increased in the callback. U-Boot continue to request the bootfs in the next GetPhase command.

| | | | | | | | | | | | | | | | | | | | | | Activate the live DT to reduce the DT parsing time. For example the boot time is reduced by 200ms on STM32MP157C-EV1 board for stm32mp15_basic_defconfig (boot with SPL) or stm32mp15_trusted_defconfig (boot with TF-A).

| * ARM: dts: stm32: Switch to MCO2 for PHY 50 MHz clockMarek Vasut2021-01-132-7/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LAN8710i PHY currently uses 50 MHz clock direct from PLL4P. To permit PLL4P to run at faster frequency, use MCO2 as a divider. The PLL4P runs at 100 MHz, supplies MCO2 which divides it by 2 to 50MHz, and supplies the PHY with 50 MHz via pin PG2. The feedback clock are fed back in via pin PA1.

| * ARM: stm32: Use firmware property instead of loadablesMichal Simek2021-01-132-5/+5
| | | | | | | | | | | | | | | | | | | | | | There shouldn't be a need to use loadables propertyn because u-boot can be pointed by firmware property. This change should also speedup boot process because loadables property is list of strings which code is going through. On the other hand firmware can just point to one image.

| * board: stm32pm1: update USB-C power detection algorithm on DK boardsPatrice Chotard2021-01-131-43/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB-C power supply which are Power Delivery compliant (USB-PD) are able to provide different voltage/current (for example 5V/3A 9V/3A 12V/2.25A...) In this case, the power supply need to negotiate the voltage/current to use with the device using CC1/CC2 USB-C signals. If this negotiation occurs during ADC measurement (done also on CC1/CC2 USB-C signals) some ADC acquisition can be corrupted which cause wrong power supply current detection. To avoid this, the power supply current detection algorithm is updated as following: - perform an ADC measurement, if a 3A current is detected, continue the boot process. - else, wait 20ms (max tPDDebounce duration) to ensure that USB-PD negotiation is done and perform another ADC measurement.
