qcom: soc: llcc-slice: Consolidate some code

2019-02-12T21:27:17Z

Make the code a little bit clearer (and use less gotos) by consolidating some of the initialization. Signed-off-by: Jordan Crouse Reviewed-by: Douglas Anderson Signed-off-by: Andy Gross

qcom: soc: llcc-slice: Clear the global drv_data pointer on error

2019-02-12T21:27:14Z

Currently the data structure for llc-slice is devm allocated and stored as a global but never cleared if the probe function fails. This is a problem because devm managed memory gets freed on probe failure the API functions could access the pointer after it has been freed. Initialize the drv_data pointer to an error and reset it to an error on probe failure or device destroy and add protection to the API functions to make sure the memory doesn't get accessed.

soc: qcom: llcc-slice: Add error checks for API functions

2018-11-14T17:59:03Z

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 tag

2018-11-14T17:56:36Z

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. Signed-off-by: Arnd Bergmann Signed-off-by: Andy Gross

soc: qcom: Add broadcast base for Last Level Cache Controller (LLCC)

2018-09-13T20:53:51Z

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.
