[PATCH] mmc: sdhci-pci-gli: Enlarge ASPM L1 entry delay of GL9763E (v2)

2021-01-14 Thread Renius Chen
GL9763E enters ASPM L1 state after a very short idle in default, even during a burst of request. So the R/W performance of GL9763E is low with some platforms, which support ASPM mechanism, due to entering ASPM L1 state very frequently in R/W process. Set the L1 entry delay bits in vendor-specific r

The R/W performance of GL9763E is low with some platforms, which support ASPM mechanism, due to entering L1 state very frequently in R/W process. Enlarge its ASPM L1 entry delay to improve the R/W performance of GL9763E. Signed-off-by: Renius Chen --- drivers/mmc/host/sdhci-pci-gli.c | 9 +++
