Although downstream supports HS400, there are overclocking warnings when using mmc-hs400-1_8v: mmc0: Card appears overclocked; req 200000000 Hz, actual 384000000 Hz mmc0: Card appears overclocked; req 200000000 Hz, actual 384000000 Hz mmc0: Card appears overclocked; req 200000000 Hz, actual 384000000 Hz mmc0: Card appears overclocked; req 400000000 Hz, actual 768000000 Hz mmc0: Card appears overclocked; req 400000000 Hz, actual 768000000 Hz mmc0: new HS400 MMC card at address 0001 Using HS200 (i.e. mmc-hs200-1_8v or mmc-ddr-1_8v) would reduce them: mmc0: Card appears overclocked; req 200000000 Hz, actual 384000000 Hz mmc0: Card appears overclocked; req 200000000 Hz, actual 384000000 Hz mmc0: new HS200 MMC card at address 0001 But as the problem is probably elsewhere (bullhead behaves the same), keep mmc-hs400-1_8v. Angler does not have SD card, thus sdhc2 kept disabled.
