firmware: ti_sci: rm: Remove unused config() from ti_sci_rm_ringacc_ops

2020-11-02T03:38:04+00:00

The ringacc driver has been converted to use the new set_cfg function to
configure the ring, the old config ops can be removed.

firmware: ti_sci: rm: Add new ops for ring configuration

2020-11-02T03:38:02+00:00

The sysfw ring configuration message has been extended to include virtid
and asel value for the ring.
Add the ASEL_VALID to TI_SCI_MSG_VALUE_RM_ALL_NO_ORDER as it is required
for DMA rings.

Instead of extending the current .config() ops - which would need same
patch change in the ringacc driver - add ti_sci_msg_rm_ring_cfg struct and
a new ops using it to configure the ring.

This will allow easy update path in case new members are added for the ring
configuration.

firmware: ti_sci: rm: Add support for extended_ch_type for tx channel

2020-11-02T03:38:01+00:00

Sysfw added 'extended_ch_type' to the tx_ch_cfg_req message which should be
used when BCDMA block copy channels are configured:
extended_ch_type = 0 : the channel is split tx channel (tchan)
extended_ch_type = 1 : the channel is block copy channel (bchan)

firmware: ti_sci: rm: Add support for second resource range

2020-11-02T03:37:59+00:00

Sysfw added support for a second range in the resource range API to be able
to describe complex allocations mainly for DMA channels.

Update the ti_sci part to consider the second range as well.

firmware: ti_sci: Use struct ti_sci_resource_desc in get_range ops

2020-11-02T03:37:59+00:00

Use the ti_sci_resource_desc directly and update it's start and num members
directly instead of requiring individual parameters for them.

This will allow easy extension of the RM parameters without changing API.

2020-11-02T03:37:58+00:00

The system controller's resource manager have support for configuring the
TDTYPE of TCHAN_CFG register on j721e.
With this parameter the teardown completion can be controlled:
TDTYPE == 0: Return without waiting for peer to complete the teardown
TDTYPE == 1: Wait for peer to complete the teardown

Pull ARM SoC-related driver updates from Olof Johansson:
 "Various driver updates for platforms. A bulk of this is smaller fixes
  or cleanups, but some of the new material this time around is:

   - Support for Nvidia Tegra234 SoC

   - Ring accelerator support for TI AM65x

   - PRUSS driver for TI platforms

   - Renesas support for R-Car V3U SoC

   - Reset support for Cortex-M4 processor on i.MX8MQ

firmware: ti_sci: allow frequency change for disabled clocks by default

2020-09-12T04:47:08+00:00

If a clock is disabled, its frequency should be allowed to change as
it is no longer in use. Add a flag towards this to the firmware clock
API handler routines.

firmware: ti_sci: Add support for getting resource with subtype

2020-08-16T21:00:22+00:00

With SYSFW ABI 3.0 changes, interrupts coming out of an interrupt
controller is identified by a type and it is consistent across SoCs.
Similarly global events for Interrupt aggregator. So add an API to get
resource range using a resource type.
