1. We always use dma for sdmmc, and it could not be used as SDIO
2. restore affected registers includes ctype and timeout
3. expose API for ISP/VICAP usage
4. remove SD3.0 support which won't affect write throughput
5. limit ffaa0000 controller only be used as sd card before ECO
6. reserve a descriptor for dirty data, in order to let DMA finish
the prior descriptors and the dirty data in the last descriptor will
not be sent at all.
7. use CMD12 + reset to clean the remain dirty data and recovery IP

For ROCKCHIP_MINI_KERNEL, it set the kmalloc min size lower than
arch dma min alignment. So the f_fs driver needs a guaranteed
cache line alignment for DMA buffer.

In mail 'RE: <rock-chips>: G610: Valhall Android DDK r36:
Does device driver warning log "Could not get a valid AS for group ..." matter?',
zhigang.yao@arm.com declared that it should not be a warning:
"This is expected behavior.
GPU has a limited present HW address space resource,
max is 16, and is implementation specific, (8 on Odin?).
So if there are more than 16 (8 on Odin) process,
some of it might not get a valid present address space,
and the warning would be printed as you have observed."

This driver use runtime PM autosuspend mechanism to manager clk.
pm_runtime_use_autosuspend(&adev->dev);
pm_runtime_set_autosuspend_delay(&adev->dev, PL330_AUTOSUSPEND_DELAY);
So, after ref count reached to zero, it will enter suspend
after the delay time elapsed.
The unbalanced PM:
* May cause dmac the next start failed.
* May cause dmac read unexpected state.
* May cause dmac stall if power down happen at the middle of the transfer.
e.g. may lose ack from AXI bus and stall.
Considering the following situation:
DMA TERMINATE TASKLET ROUTINE
| |
| issue_pending
| |
| pch->active = true
| pm_runtime_get
pm_runtime_put(if active) |
pch->active = false |
| work_list empty
| |
| pm_runtime_put(force)
| |
At this point, it's unbalanced(1 get / 2 put).
After this patch:
DMA TERMINATE TASKLET ROUTINE
| |
| issue_pending
| |
| pch->active = true
| pm_runtime_get
pm_runtime_put(if active) |
pch->active = false |
| work_list empty
| |
| pm_runtime_put(if active)
| |
Now, it's balanced(1 get / 1 put).
