But this is not clear from the semantic point-of-view, and there is no public documentation about that either. After discussing this in the mailing-lists [0] and having Florian explained it very well, document that in the code for the future generations asking the same questions. Also, while at it, remove a useless header.

Adding use of MMIO regmap and regmap fields which allows to keep one code logic with different register maps. 2. The "clear" type registers do not allow reading, therefore regmap requires using cache with default values. 3. regmap has an effect of introducing barriers after each readl/writel, which should negligible effect as only few writes were relaxed. 4. Additionally usage of regmap fields removes need of shifting the register values. 5. Add "V4" prefix to names of all defines with register addresses (so BWMON_V4_xxx) to differentiate it from V5. The actual register values are shared so keep their naming. 6. While changing the defines, pad register addresses to three digits for readability.

The already supported one monitors traffic between CPU and Last Level Cache Controller (LLCC) and in downstream sources is called BWMON v4 (or v4 of register layout). SDM845 also has also BWMON instance measuring traffic between LLCC and memory with different register layout: called v5. Add support for this "LLCC" BWMON. Differences against existing v4 one: 1. No global interrupts. 2. Different register layout. 3. Different shift of interrupt fields. 4. Smaller sampling window.

This prevents clients from registering const arrays. Since these arrays are always pre-defined, they should be const, so add the const qualifier to all places in the QMI interface where struct qmi_elem_info is used. Once this patch is in place, clients can independently update their pre-defined arrays to be const, as demonstrated in the QMI sample code.

For instance, starting from version v1.0.0 to v2.0.1 the offsets are same. And starting from v2.1.0, the offsets changed. But the current reg_offset naming convention is confusing. So to reflect this change correctly in driver, let's encode the start version from which the offsets got changed in reg_offset struct name. This will be llcc_v1_reg_offset for v1.0.0 and llcc_v2_1_reg_offset for v2.1.0. This will allow multiple SoCs to use the same reg_offset clearly. And in the future if the offsets got changed again, then that specific version could be encoded in the struct name.

Until now, the EDAC driver used the hardcoded register offsets. But this caused crash on SM8450 SoC where the register offsets has been changed. So to avoid this crash and also to make it easy to accommodate changes for new SoCs, let's pass the LLCC version specific register offsets to the EDAC driver. Currently, two set of offsets are used. One is starting from LLCC version v1.0.0 used by all SoCs other than SM8450. For SM8450, LLCC version starting from v2.1.0 is used.

ERD bit allows masking of SError due to inband errors which are caused by illegal register accesses through CBB. When the bit is set, interrupt is used for reporting errors and magic code '0xdead2003' is returned. This change is only required for Tegra194 SoC as the config is moved to CBB register space for future SoC's. Also, remove unmapping the apbmisc_base as it's required to get the base address for accessing the misc register.

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.

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.

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.
