Merge tag 'riscv-for-linus-5.16-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V fixes from Palmer Dabbelt: - A handful of DT updates for the SiFive HiFive Unmatched, that fix the regulator handling. These should stop some warning spew. - A pair of fixes for both the SiFive Hifive Unleashed and Unmatched, that correctly hook up the MMC card detect signal. * tag 'riscv-for-linus-5.16-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: dts: sifive unmatched: Link the tmp451 with its power supply riscv: dts: sifive unmatched: Fix regulator for board rev3 riscv: dts: sifive unmatched: Expose the PMIC sub-functions riscv: dts: sifive unmatched: Expose the board ID eeprom riscv: dts: sifive unmatched: Name gpio lines riscv: dts: unmatched: Add gpio card detect to mmc-spi-slot riscv: dts: unleashed: Add gpio card detect to mmc-spi-slot
