2021-09-12[NOT-FOR-UPSTREAM] Add build instructionsbeaglev-5.13.yEmil Renner Berthing9-0/+449
For convenience this also adds a small beaglev_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.

2021-09-12riscv: dts: Add early A1 variant of the BeagleV Starlight boardEmil Renner Berthing2-1/+26
This is an early version of the BeagleV Starlight board that has GPIO63 wired up to tell the PMIC to reset the whole board rather than just the ethernet phy as it does on the later versions sent out as part of the BeagleV beta program. Signed-off-by: Emil Renner Berthing <kernel@esmil.dk>

2021-09-12RISC-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.

2021-09-12pinctrl: starfive: Reset pinmux settingsEmil Renner Berthing2-0/+72
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.

2021-09-12pinctrl: starfive: Add pinctrl driver for the JH7100 SoCEmil Renner Berthing5-0/+1705
This adds a combined pinctrl and gpio driver for the StarFive Ltd. JH7100 RISC-V SoC [1]. For each "GPIO" there are two registers for configuring the output and output enable signals, which may come from other peripherals, and controlling the GPIOs from software amounts to setting these signals to constant 0 or constant 1. In other words the same registers are used for both pinmuxing and controlling the GPIOs, which makes it easier to combine the pinctrl and gpio driver in one. The gpio code is adapted from the gpio driver in the vendor tree written by Huan Feng with cleanups and fixes by Drew and me.

Add a preliminary driver for the StarFive JH7100 Clock Generator, based on work by Ahmad Fatoum for Barebox. Functional differences compared to the Barebox driver: - Addition of starfive_clk_pll_mult(), to make the PLL outputs reasonable, - Add temporary overrides for critical clocks (uart, i2c, spi) until we get the clock tree right, so we don't have to keep dummy clocks like uartclk and hs_uartclk in the DTS.
