soc/tegra: fuse: Drop Kconfig dependency on TEGRA20_APB_DMA

2022-10-26T11:25:29Z

[ Upstream commit 2254182807fc09ba9dec9a42ef239e373796f1b2 ] The DMA subsystem could be entirely disabled in Kconfig and then the TEGRA20_APB_DMA option isn't available too. Hence kernel configuration fails if DMADEVICES Kconfig option is disabled due to the unsatisfiable dependency. The FUSE driver isn't a critical driver and currently it only provides NVMEM interface to userspace which isn't known to be widely used, and thus, it's fine if FUSE driver fails to load. Let's remove the erroneous Kconfig dependency and let the FUSE driver to fail the probing if DMA is unavailable.

soc/tegra: regulators: Add regulators coupler for Tegra30

2019-10-29T13:02:59Z

Add regulators coupler for Tegra30 SoCs that performs voltage balancing of a coupled regulators and thus provides voltage scaling functionality. There are 2 coupled regulators on all Tegra30 SoCs: CORE and CPU. The coupled regulator voltages shall be in a range of 300mV from each other and CORE voltage shall be higher than the CPU by N mV, where N depends on the CPU voltage.

soc/tegra: regulators: Add regulators coupler for Tegra20

2019-10-29T13:02:59Z

Add regulators coupler for Tegra20 SoCs that performs voltage balancing of a coupled regulators and thus provides voltage scaling functionality. There are 3 coupled regulators on all Tegra20 SoCs: CORE, RTC and CPU. The CORE and RTC voltages shall be in range of 170mV from each other and they both shall be higher than the CPU voltage by at least 120mV. This sounds like it could be handle by a generic voltage balancer, but the CORE voltage scaling isn't implemented in any of the upstream drivers yet. It will take quite some time and effort to hook up voltage scaling for all of the drivers, hence we will use a custom coupler that will manage the CPU voltage scaling for the starter.
