Subject: [PATCH 450/464] soc: rockchip: grf: Fix SD card errors during boot
|
||
|
|
when bus-width > 1
|
||
|
|
|
||
|
|
RK3588 has the same issue as other earlier RK SoCs. JTAG
|
||
|
|
functionality muxed to some SDMMC data pins causes issues with SDMMC
|
||
|
|
interface. Without this patch, I can only use SDMMC inteface
|
||
|
|
with bus-width = <1>. (JTAG is muxed to data pins D2 and D3)
|
||
|
