[PATCH 0/2] Validate and clean up UHS/DDR/HS200 timing checks

From: Shawn Lin

Date: Fri Mar 06 2026 - 07:57:30 EST



This series adds validation for UHS/DDR/HS200 timing modes when the host
only supports 1-bit bus width which also fixes a real performance drop issue
due to incorrect hs200 mode switch code. And then cleans up the check in
mmc_host_can_uhs().


Luke Wang (1):
mmc: core: Validate UHS/DDR/HS200 timing selection for 1-bit bus width

Shawn Lin (1):
mmc: core: Remove checking MMC_CAP_4_BIT_DATA from mmc_host_can_uhs()
