Subject: [PATCH v1 0/2] eMMC RST_N support on BlueField-2 SoC
Date: Wed, 12 Jun 2024 18:52:36 -0400 [thread overview]
Message-ID: <cover.1718213918.git.limings@nvidia.com> (raw)
The dw_mmc driver supports eMMC RST_N recovery flow but doesn't work
on BlueField-2 SoC because the RST_N register is designed as secure
register. This patch series enhance the dw_mci_drv_data structure to
support platform-specific hw_reset(), then implements this function in
dw_mmc-bluefield.c to support RST_N via SMC call.
Liming Sun (2):
dw_mmc: support platform specific hw_reset()
dw_mmc-bluefield: add hw_reset() support
