soc/tegra: Fix an error handling path in tegra_powergate_power_up()

2021-11-18T18:16:51+00:00

[ Upstream commit 986b5094708e508baa452a23ffe809870934a7df ] If an error occurs after a successful tegra_powergate_enable_clocks() call, it must be undone by a tegra_powergate_disable_clocks() call, as already done in the below and above error handling paths of this function. Update the 'goto' to branch at the correct place of the error handling path.

soc/tegra: fuse: Enable fuse clock on suspend for Tegra124

2021-08-11T09:55:56+00:00

The FUSE clock should be enabled during suspend on Tegra124. Currently clk driver enables it on all SoCs, but FUSE may require a higher core voltage on Tegra30 while enabled. Move the quirk into the FUSE driver and make it specific to Tegra124. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

soc/tegra: fuse: Add runtime PM support

2021-08-11T09:55:04+00:00

The Tegra FUSE belongs to the core power domain and we're going to enable GENPD support for the core domain. Now FUSE device must be resumed using runtime PM API in order to initialize the FUSE power state. Add runtime PM support to the FUSE driver.

soc/tegra: fuse: Clear fuse->clk on driver probe failure

2021-08-11T09:54:48+00:00

The fuse->clk must be cleared if FUSE driver fails to probe, otherwise tegra_fuse_readl() will crash. It's unlikely to happen in practice, nevertheless let's correct it for completeness. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

soc/tegra: pmc: Prevent racing with cpuilde driver

2021-08-11T09:51:39+00:00

Both PMC and cpuidle drivers are probed at the same init level and cpuidle depends on the PMC suspend mode. Add new default suspend mode that indicates whether PMC driver has been probed and reset the mode in a case of deferred probe of the PMC driver.

soc/tegra: Make regulator couplers depend on CONFIG_REGULATOR

2021-08-02T12:30:46+00:00

The regulator coupler drivers now use regulator-driver API function that isn't available during compile-testing. Make regulator coupler drivers dependent on CONFIG_REGULATOR in Kconfig.

This branch also contains a few of the fixes that weren't sent in by the end of the release (all fairly minor). - Adding an additional maintainer for the TEE subsystem (Sumit Garg) - Quite a significant modernization of the IXP4xx platforms by Linus Walleij, revisiting with a new PCI host driver/binding, removing legacy mach/* include dependencies and moving platform detection/config to drivers/soc. Also some updates/cleanup of platform data. - Core power domain support for Tegra platforms, and some improvements in build test coverage by adding stubs for compile test targets. - A handful of updates to i.MX platforms, adding legacy (non-PSCI) SMP support on i.MX7D, SoC ID setup for i.MX50, removal of platform data and board fixups for iMX6/7. ... and a few smaller changes and fixes for Samsung, OMAP, Allwinner, Rockchip" * tag 'arm-soc-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (53 commits) MAINTAINERS: Add myself as TEE subsystem reviewer ixp4xx: fix spelling mistake in Kconfig "Devce" -> "Device" hw_random: ixp4xx: Add OF support hw_random: ixp4xx: Add DT bindings hw_random: ixp4xx: Turn into a module hw_random: ixp4xx: Use SPDX license tag hw_random: ixp4xx: enable compile-testing pata: ixp4xx: split platform data to its own header soc: ixp4xx: move cpu detection to linux/soc/ixp4xx/cpu.h PCI: ixp4xx: Add a new driver for IXP4xx PCI: ixp4xx: Add device tree bindings for IXP4xx ARM/ixp4xx: Make NEED_MACH_IO_H optional ARM/ixp4xx: Move the virtual IObases MAINTAINERS: ARM/MStar/Sigmastar SoCs: Add a link to the MStar tree ARM: debug: add UART early console support for MSTAR SoCs ARM: dts: ux500: Fix LED probing ARM: imx: add smp support for imx7d ARM: imx6q: drop of_platform_default_populate() from init_machine arm64: dts: rockchip: Update RK3399 PCI host bridge window to 32-bit address memory soc/tegra: fuse: Fix Tegra234-only builds ...
