Other Parts Discussed in Thread: TMS320DM355, AM1808
The Davinci SDIO patch in https://patchwork.kernel.org/patch/85936/ contains a workaround for interrupt checking on the TMS320DM355 as described in "TMS320DM355 Silicon Revision 1.1 Errata, section 2.1.5".
Netiher the AM1808 MMC/SD/SDIO Reference nor the AM1808 Errata document does mention this workaround. So does the errata mentioned in TMS320DM355 still apply to the AM1808 or is this information obsolete as the MMC-controller is a version 2 one?
