pmdomain: tegra: Move Kconfig option to the pmdomain subsystem

2023-10-04T21:41:56Z

The Kconfig option belongs closer to the corresponding implementation, hence let's move it from the soc subsystem to the pmdomain subsystem. Cc: Thierry Reding Cc: Jonathan Hunter Cc: Mikko Perttunen Cc: Signed-off-by: Ulf Hansson

soc: tegra: fix CPU_BIG_ENDIAN dependencies

My previous patch to prevent BPMP from being enabled on big endian kernels caused a build regression: WARNING: unmet direct dependencies detected for TEGRA_BPMP Depends on [n]: ARCH_TEGRA [=y] && TEGRA_HSP_MBOX [=y] && TEGRA_IVC [=y] && !CPU_BIG_ENDIAN [=y] Selected by [y]: - ARCH_TEGRA_186_SOC [=y] && ARCH_TEGRA [=y] && ARM64 [=y] - ARCH_TEGRA_194_SOC [=y] && ARCH_TEGRA [=y] && ARM64 [=y] - ARCH_TEGRA_234_SOC [=y] && ARCH_TEGRA [=y] && ARM64 [=y] Add even more such dependencies for the SoC types that use the BPMP driver.

soc/tegra: fuse: Drop Kconfig dependency on TEGRA20_APB_DMA

2022-09-15T10:49:14Z

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: cbb: Add driver for Tegra234 CBB 2.0

2022-09-15T10:41:36Z

Adding driver to handle errors from CBB version 2.0 which is used in Tegra234 SoC. The driver prints debug information about failed transaction on receiving interrupt from the error notifier. The error notifier collates the interrupts from various error monitor blocks and presents a single interrupt to the SoC interrupt controller. For timeout errors, the driver also does the lookup to find timed out clients and prints their client ID. Drivers for hardware that needs to be reset on timeout will have to call BPMP from the client IP's driver. BPMP firmware will also clear the timeout bit after resetting the IP so that next transactions are send to them after reset. Signed-off-by: Sumit Gupta Signed-off-by: Thierry Reding

soc/tegra: cbb: Add CBB 1.0 driver for Tegra194

2022-09-15T10:41:36Z

Adding driver to handle errors from Control Backbone (CBB) which are generated due to illegal accesses. CBB 1.0 is used in Tegra194 SoCs. When an error is reported from a NOC within CBB, the driver prints debug information about failed transaction like Error Code, Error Description, Master, Address, AXI ID, Cache, Protection, Security Group etc. It then causes system crash using BUG_ON() or call WARN() based on whether the error type is fatal or not.

soc/tegra: pmc: Select REGMAP

2022-05-04T09:09:49Z

Commit 9d5e7c3e36eb ("soc/tegra: pmc: Provide USB sleepwalk register map") introduced a dependency on the regmap infrastructure, so select the corresponding Kconfig entry. This avoids failures in random builds that may otherwise end up having SOC_TEGRA_PMC enabled but not REGMAP. Signed-off-by: Thierry Reding
