treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 471

2019-06-19T15:09:11+00:00

Based on 1 normalized pattern(s): released under the gplv2 only spdx license identifier gpl 2 0 extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 3 file(s).

memory: brcmstb: dpfe: introduce DPFE API v3

2019-05-20T16:32:35+00:00

Introduce code to handle DPFE API v3. We also change the driver to default to v3 by default and use API v2 only for select chips. Signed-off-by: Markus Mayer Signed-off-by: Florian Fainelli

memory: brcmstb: dpfe: prepare for API-dependent sysfs attributes

2019-05-20T16:32:35+00:00

Prepare the driver so that sysfs attributes can differ based on the API version. Signed-off-by: Markus Mayer Signed-off-by: Florian Fainelli

memory: brcmstb: dpfe: prepare support for multiple API versions

2019-05-20T16:32:35+00:00

Extend the driver, so it can handle different API versions for interacting with the DCPU. This is in preparation for the upcoming API v3. Signed-off-by: Markus Mayer Signed-off-by: Florian Fainelli

memory: brcmstb: dpfe: wait for DCPU to be ready

2019-05-20T16:32:35+00:00

We wait for the DCPU to be ready before sending a command. Signed-off-by: Markus Mayer Signed-off-by: Florian Fainelli

Remove an unused struct and fix source code formatting in a few areas. Signed-off-by: Markus Mayer Signed-off-by: Florian Fainelli

memory: brcmstb: dpfe: use byte 3 of registers MR4-MR8

2019-05-20T16:32:35+00:00

For dual-rank LPDDR4, result data for any command is placed in byte 0 and byte 3 of the corresponding MR register by the firmware. Single-rank RAM was supposed to work the same way. However, due to a firmware bug, result values are only placed in byte 3 of the corresponding MR register. Since byte 3 works for single-rank and dual-rank setups, we change the Linux driver to always use byte 3, thus returning the correct value in either case.

memory: brcmstb: dpfe: optimize generic_show()

2019-05-20T16:32:35+00:00

We can pass a (struct priv_data *) to generic_show() rather than a (struct device *). For two of the three callers of this function, the change means one less call to dev_get_drvdata(). For the third caller, it makes no difference. Signed-off-by: Markus Mayer Signed-off-by: Florian Fainelli
