* clk: starfive-jh7100: Fix duplicate numbersGeert Uytterhoeven2021-06-251-2/+2
| | | | | | | | Fixes: 6f92e74e5b94d8e6 ("clk: add initial StarFive clock support") Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Tested-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Link: https://lore.barebox.org/20210624150931.891123-1-geert@linux-m68k.org Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* reset: add StarFive reset controller driverAhmad Fatoum2021-06-241-0/+126
| | | | | | | | | | | | | | | | The StarFive SoC has a single reset controller, which seems to control reset of all clocks and peripherals. It differs from the ones supported by the Linux reset-simple driver in that it has a dedicated status registers that needs to be polled to verify the reset has completed. Also special is that most resets (> 70) are synchronous. As the reset status poll would just time out without the clock, have the reset controller enable the clock as part of the reset. OS can decide later, which clocks to disable again.

* clk: add initial StarFive clock supportAhmad Fatoum2021-06-241-0/+203
| | | | | | | | | | | | | | | | | | | | | | All clocks seem to share a common format: struct starfive_clk { u32 divisor : 24; /* LSB */ u32 mux : 6; u32 invert : 1; u32 enable : 1; /* MSB */ }; There is no documentation, what the acceptable divisor values are, but we could already register gates and muxes, do so for now until documentation is available. The bulk of this code has been machine-generated by parsing the macros in the vendor U-Boot <asm/arch-vic7100/clkgen_ctrl_macro.h>.

* reset: remove duplicate imx8mq-reset.h and use correct definesLucas Stach2020-03-231-64/+0
| | | | | | | | | | | | The defines in the Barebox copy of imx8mq-reset.h had a typo, which has been fixed in the upstream Linux version of this file. So depending on include ordering the reset driver using those defines would fail to compile. Use the typo fixed versions of the define in the driver and remove the duplicate include file, as we also have the proper upstream version now.
