Subject: [PATCH 0988/1085] drivers: sdhci-brcmstb: work around mystery CQE
|
|
CMD_IDLE_TIMER trampling
|
|
|
|
For unknown reasons the controller seems to reset the idle polling timer
|
|
interval on CQE enable/disable to 8 clocks which is extremely short.
|
|
|
|
Just use the reset value in the eMMC spec (4096 clock periods which at
|
|
200MHz is ~20uS).
