memory: tegra20-emc: Add runtime dependency on devfreq governor module

2021-10-21T09:18:08Z

Tegra20 EMC driver uses simple devfreq governor. Add simple devfreq governor to the list of the Tegra20 EMC driver module softdeps to allow userspace initramfs tools like dracut to automatically pull the devfreq module into ramfs image together with the EMC module.

memory: tegra20-emc: Support matching timings by LPDDR2 configuration

2021-10-15T07:52:47Z

ASUS Transformer TF101 doesn't provide RAM code and in this case memory timings should be selected based on identity information read out from SDRAM chip. Support matching timings by LPDDR2 configuration. Signed-off-by: Dmitry Osipenko Link: https://lore.kernel.org/r/20211006224659.21434-10-digetx@gmail.com Signed-off-by: Krzysztof Kozlowski

2021-09-20T08:33:28Z

The return value from tegra_bpmp_transfer indicates the success or failure of the IPC transaction with BPMP. If the transaction succeeded, we also need to check the actual command's result code. Add code to do this. Signed-off-by: Mikko Perttunen Link: https://lore.kernel.org/r/20210915085517.1669675-3-mperttunen@nvidia.com Signed-off-by: Krzysztof Kozlowski

memory: tegra: Remove interconnect state syncing hack

2021-09-20T08:32:53Z

State syncing works properly now, previously the sync callback was never invoked. Apparently it was fixed in drivers core, so let's remove the hack. The state won't be synced until all consumer drivers of devices that reference memory controller in a device-tree are probed, i.e. keeping bandwidth at maximum until both display and devfreq drivers are probed.
