[WIP] dt-bindings: dma: dw-axi-dmac: Increase DMA channel limit to 16

2021-08-26T21:07:32+00:00

The first DMAC instance in the StarFive JH7100 SoC supports 16 DMA channels. FIXME Given there are more changes to the driver than just increasing DMAC_MAX_CHANNELS, we probably need a new compatible value, too. Signed-off-by: Geert Uytterhoeven

mfd: tps65086: Make interrupt line optional

2021-08-26T21:07:32+00:00

The BeagleV Starlight v0.9 board[1] doesn't have the IRQB line routed to the SoC, but it is still useful to be able to reach the PMIC over I2C for the other functionality it provides such as GPIOs and regulator settings.

dt-bindings: mfd: convert tps65086.txt to YAML

2021-08-26T21:07:32+00:00

This converts the tps65086.txt binding description to YAML schema so dts files can be verified automatically. Signed-off-by: Emil Renner Berthing

pinctrl: starfive: Reset pinmux settings

2021-08-26T21:07:31+00:00

Current u-boot doesn't seem to take into account that some GPIOs are configured as inputs/outputs of certain peripherals on power-up. This means it ends up configuring some GPIOs as inputs to more than one peripheral which the documentation explicitly says is illegal. Similarly it also ends up configuring more than one GPIO as output of the same peripheral. While not explicitly mentioned by the documentation this also seems like a bad idea. The easiest way to remedy this mess is to just disconnect all GPIOs from peripherals and have our pinmux configuration set everything up properly. This, however, means that we'd disconnect the serial console from its pins for a while, so add a device tree property to keep certain GPIOs from being reset. Signed-off-by: Emil Renner Berthing
