2022-11-14soc: imx8m: Enable OCOTP clock before reading the registerXiaolei Wang1-0/+11
Commit 7d981405d0fd ("soc: imx8m: change to use platform driver") ever removed the dependency on bootloader for enabling OCOTP clock. It helped to fix a kexec kernel hang issue. But unfortunately it caused a regression on CAAM driver and got reverted. This is the second try to enable the OCOTP clock by directly calling clock API instead of indirectly enabling the clock via nvmem API.

2022-09-26pxa: Drop if with an always false conditionUwe Kleine-König1-5/+1
The remove callback is only called after probe completed successfully. In this case platform_set_drvdata() was called with a non-NULL argument and so ssp is never NULL. Also note that returning an error code from a remove callback doesn't result in the device staying bound. It's still removed and devm callbacks are called. So the memory that ssp pointed to during probe, goes away without the node being removed from ssp_list. The probable result of an early exit is accessing freed memory when the list is walked the next time. Signed-off-by: Uwe Kleine-König <(address hidden)> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Commit 9a073d4fbb18 ("soc: bcm: brcmstb: biuctrl: Add missing of_node_put()") added what was thought to be a missing of_node_put() but now causes a double of_node_put() to be called, once from setup_hifcpubiuctrl_regs() and another time from brcmstb_biuctrl_init(). Ensure that setup_hifcpubiuctrl_regs() is not calling of_node_put() since it is not obvious it does that on one of its parameters.

MT6795 has the same mutex mod/sof register layout as MT2712 and MT8173, but supports only four SOF, as it has two DSI and one DPI. Support is added by reusing most of the MT8173 data, with the addition of a mt6795-specific SOF array (and devicetree compatible, of course).

2022-09-15soc/tegra: fuse: Drop Kconfig dependency on TEGRA20_APB_DMADmitry Osipenko1-1/+0
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.

2022-09-15soc/tegra: cbb: Add support for Tegra241 (Grace)Sumit Gupta1-2/+269
Adding support for Tegra241 (Grace) which uses fabrics based on the CBB 2.0 architecture. Since Tegra241 requires ACPI, implement ACPI-based probe support. Fabrics reporting errors in Tegra241 are "CBB" and "BPMP". The CBB fabric connects various other CBB 2.0 based fabrics and also services the Initiators and Targets which are connected to itself. The BPMP fabric is present in the BPMP cluster. Signed-off-by: Sumit Gupta <sumitg@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2022-09-15soc/tegra: cbb: Add driver for Tegra234 CBB 2.0Sumit Gupta3-1/+848
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.

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.
