Merge tag 'bitmain-soc-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mani/linux-bitmain into arm/dt
Bitmain SoC changes for v5.4: Most of the basic infrastructure is completed for BM1880 SoC except common clock support. We are still couple of patchset away from booting a distro from eMMC/SD with mainline. Below are the changes for this cycle: - Added Reset controller support to BM1880 SoC based on reset-simple driver. - Modified pinctrl memory map for BM1880 SoC. The initial pinctrl support included the PWM registers as a part of the pinctrl memory map. But this turned out to be useless as PWM registers are not handling any pin muxing at all. So removed the PWM registers from pinctrl memory map. * tag 'bitmain-soc-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mani/linux-bitmain: arm64: dts: bitmain: Modify pin controller memory map arm64: dts: bitmain: Add reset controller support for BM1880 SoC Signed-off-by: Arnd Bergmann <arnd@arndb.de>
