2022-01-05[NOT-FOR-UPSTREAM] Add build instructionsvisionfive-5.15.yEmil Renner Berthing10-0/+492
For convenience this also adds a small visionfive_defconfig and the firmware needed for the brcmfmac driver along with the signed regulatory database. The firmware is from the linux-firmware repo and the regulatory database from the wireless-regdb Fedora package.

2022-01-05RISC-V: Support non-coherent DMA operationsAtish Patra4-0/+79
** Do not upstream ** This is hacky fix just for testing. The actual patch would read the RISCV_UNCACHED_OFFSET from the DT for only the non-coherent devices. All other devices on beagleV and all other platform should just set dma_default_coherent to true.

2022-01-05pinctrl: starfive: Reset pinmux settingsEmil Renner Berthing2-0/+70
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.

2022-01-05reset: starfive: Add JH7100 audio reset driverEmil Renner Berthing6-15/+112
The audio resets are almost identical to the system resets, there are just fewer of them. So factor out and export a generic probe function, so most of the reset controller implementation can be shared. Signed-off-by: Emil Renner Berthing <kernel@esmil.dk>
2022-01-05reset: starfive: Use 32bit I/O on 32bit registersEmil Renner Berthing1-20/+20
The driver currently uses 64bit I/O on the 32bit registers. This works because there are 4 assert registers and 4 status register, so they're only ever accessed on 64bit boundaries. There are however other reset controllers for audio and video on the SoC with only one status register that isn't 64bit aligned so 64bit I/O would result in an unaligned access exception. Switch to 32bit I/O in preparation for supporting these resets too. Signed-off-by: Emil Renner Berthing <kernel@esmil.dk>
