ata: ahci_tegra: set SATA0_INDEX_0_CH1 before prod

2018-07-02T08:13:18+00:00

Currently, the SATA DT contains enabling and disabling of SATA0_INDEX_0_CH1
which is required for enabling write access to  0x03501690 and 0x03501694.
The prod node should only have prod settings from the GR Database.
So this patch changes the sequence as below:
set SATA0_INDEX_0_CH1 -> apply prod settings -> reset SATA0_INDEX_0_CH1.

ata: ahci_tegra: switch to BPMP powergate provider

2018-05-30T06:26:52+00:00

The runtime PM subsystem can also handle turning powergates, or power domains,
on and off as needed. This is handled by the 'generic power domain', or genpd
system. The system ensures that a power domain is powered on when any device
contained to it is powered on, and when all are powered off, the power domain
will be powered off as well.

When using runtime PM and genpd, the driver itself does not need to include
any code related to powergating. The power domain will be powered on and off
as required, as long as the runtime PM functions are used.
