soc: mediatek: mutex: add functions that operate registers by CMDQ

2022-06-17T13:51:52+00:00

Due to HW limitations, MDP3 is necessary to enable MUTEX in each frame
for SOF triggering and cooperate with CMDQ control to reduce the amount
of interrupts generated(also, reduce frame latency).

In response to the above situation, a new interface
"mtk_mutex_enable_by_cmdq" has been added to achieve the purpose.

soc: mediatek: mutex: add common interface for modules setting

2022-06-17T13:51:51+00:00

In order to allow multiple modules to operate MUTEX hardware through
a common interfrace, two flexible indexes "mtk_mutex_mod_index" and
"mtk_mutex_sof_index" need to be added to replace original component
ID so that like DDP and MDP can add their own MOD table or SOF
settings independently.

In addition, 2 generic interface "mtk_mutex_write_mod" and
"mtk_mutex_write_sof" have been added, which is expected to replace
the "mtk_mutex_add_comp" and "mtk_mutex_remove_comp" pair originally
dedicated to DDP in the future.

 "These updates are for platform specific code in arch/arm/, mostly
  fixing minor issues.

  The at91 platform gains support for better power management on the
  lan966 platform and new firmware on the sama5 platform. The mediatek
  soc drivers in turn are enabled for the new mt8195 SoC"

soc: mediatek: add DDP_DOMPONENT_DITHER0 enum for mt8195 vdosys0

2022-04-22T12:38:53+00:00

The mmsys routing table of mt8195 vdosys0 has 2 DITHER components,
so mmsys need to add DDP_COMPONENT_DITHER1 and change all usages of
DITHER enum form DDP_COMPONENT_DITHER to DDP_COMPONENT_DITHER0.

But its header need to keep DDP_COMPONENT_DITHER enum
until drm/mediatek also changed it.

soc: mediatek: cmdq: Use mailbox rx_callback instead of cmdq_task_cb

2022-04-20T12:14:59+00:00

rx_callback is a standard mailbox callback mechanism and could cover the
function of proprietary cmdq_task_cb, so use the standard one instead of
the proprietary one. Client has changed to use the standard callback
machanism and sync dma buffer in client driver, so remove the proprietary
callback in cmdq helper.

net: ethernet: mtk_eth_soc: add support for Wireless Ethernet Dispatch (WED)

2022-04-06T13:08:49+00:00

The Wireless Ethernet Dispatch subsystem on the MT7622 SoC can be
configured to intercept and handle access to the DMA queues and
PCIe interrupts for a MT7615/MT7915 wireless card.
It can manage the internal WDMA (Wireless DMA) controller, which allows
ethernet packets to be passed from the packet switch engine (PSE) to the
wireless card, bypassing the CPU entirely.
This can be used to implement hardware flow offloading from ethernet to
WLAN.

soc: mediatek: mtk-infracfg: Disable ACP on MT8192

2022-03-01T07:21:28+00:00

MT8192 contains an experimental Accelerator Coherency Port
implementation, which does not work correctly but was unintentionally
enabled by default. For correct operation of the GPU, we must set a
chicken bit disabling ACP on MT8192.

Adapted from the following downstream change to the out-of-tree, legacy
Mali GPU driver:

https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/2781271/5

Note this change is required for both Panfrost and the legacy kernel
driver.
