* soc: qcom: llcc-slice: Add error checks for API functionsJordan Crouse2018-11-141-1/+14
| | | | | | | | | | | llcc_slice_getd can return a ERR_PTR code on failure. Add a IS_ERR_OR_NULL check to subsequent API calls that use struct llcc_slice_desc to guard against faults and to let the leaf drivers get away with safely using a ERR_PTR() encoded "pointer" in the aftermath of a llcc_slice_getd error.

* soc: qcom/llcc: add MODULE_LICENSE tagArnd Bergmann2018-11-141-1/+2
| | | | | | | | | | | | The lack of a MODULE_LICENSE tag prevents building the llcc driver as a loadable module: FATAL: modpost: GPL-incompatible module llcc-slice.ko uses GPL-only symbol 'ktime_get' This adds the appropriate license and description tags.

* soc: qcom: Add support to register LLCC EDAC driverVenkata Narendra Kumar Gutta2018-09-131-2/+16
| | | | | | | | | | | Cache error reporting controller detects and reports single and double bit errors on Last Level Cache Controller (LLCC) cache. Add required support to register LLCC EDAC driver as platform driver, from LLCC driver.

* soc: qcom: Add broadcast base for Last Level Cache Controller (LLCC)Venkata Narendra Kumar Gutta2018-09-131-22/+33
| | | | | | | | | | | | | Currently, broadcast base is set to end of the LLCC banks, which may not be correct always. As the number of banks may vary for each chipset and the broadcast base could be at a different address as well. This info depends on the chipset, so get the broadcast base info from the device tree (DT). Add broadcast base in LLCC driver and use this for broadcast writes.

LLCC (Last Level Cache Controller) provides additional cache memory in the system. LLCC is partitioned into multiple slices and each slice gets its own priority, size, ID and other config parameters. LLCC driver programs these parameters for each slice. Clients that are assigned to use LLCC need to get information such size & ID of the slice they get and activate or deactivate the slice as needed. LLCC driver provides API for the clients to perform these operations.
