Hi Siva, Michal.
I noticed drivers/mmc/sdhci-cadence.c not working for my boards.
git-bisect points the following commit:
commit 434f9d454eb1a17bb7f5cdb21167ccbe7e41da39 Author: Siva Durga Prasad Paladugu siva.durga.paladugu@xilinx.com Date: Tue May 29 20:03:10 2018 +0530
mmc: sdhci: Update sdhci_send_command() to handle HS200 This patch updates sdhci_send_command() to handle MMC HS200 tuning command. Signed-off-by: Siva Durga Prasad Paladugu <siva.durga.paladugu@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>By reverting it, I can get the MMC on my boards working again.
Any idea to fix it?
BTW, 'mmc info' looks like follows on the bad commit:
