If anyone has any objections, please let me know. ------------------ From: Vladimir Zapolskiy [ Upstream commit 93f823e7d48232e62fb8fb74481696609c90244a ] The restriction on UHS-I speed modes was added to all SM8650 platforms by copying it from SM8450 and SM8550 dtsi files, and it was an actually reproducible problem due to the overclocking of SD cards. Since the latter issue has been fixed in the SM8650 GCC driver, UHS-I speed modes are working fine on SM8650 boards, below is the test performed on SM8650-HDK: SDR50 speed mode: mmc0: new UHS-I speed SDR50 SDHC card at address 0001 mmcblk0: mmc0:0001 00000 14.6 GiB mmcblk0: p1 % dd if=/dev/mmcblk0p1 of=/dev/null bs=1M count=1024 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 24.8086 s, 43.3 MB/s SDR104 speed mode: mmc0: new UHS-I speed SDR104 SDHC card at address 59b4 mmcblk0: mmc0:59b4 USDU1 28.3 GiB mmcblk0: p1 % dd if=/dev/mmcblk0p1 of=/dev/null bs=1M count=1024 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 12.9448 s, 82.9 MB/s Unset the UHS-I speed mode restrictions from the SM8550 platform dtsi file, there is no indication that the SDHC controller is broken.
