Subject: [PATCH V3 1/1] mmc: sdhci: Fix the SD tuning issue that the SDHCI_TRANSFER_MODE is cleared incorrectly
Date: Fri, 11 Nov 2022 04:23:14 -0800 [thread overview]
Message-ID: <20221111122314.307-1-charl.liu@bayhubtech.com> (raw)
When cmd->opcode == MMC_SEND_TUNING_BLOCK, the SDHCI_TRANSFER_MODE
should also be kept
Signed-off-by: Charl Liu <charl.liu@bayhubtech.com>
---
change in V1:
Keeping the SDHCI_TRANSFER_MODE when cmd->opcode == MMC_END_TUNING_BLOCK
change in V2:
add the mmc_op_tuning interface to judge if the opcode is tuning CMD
change in V3:
cancel the redundant code
