| Subject | [PATCH 1/2] ARM: dts: am57xx-beagle-x15: Remove pinmux configurations |
| Date | 2016-09-02 11:10 +0200 |

pinmuxing for DRA7x/AM57x family of processors need to be done in IO
isolation as part of initial bootloader executed from SRAM. This is
done as part of iodelay configuration sequence and is required due to
the limitations introduced by erratum ID: i869[1] and elaborated in
the Technical Reference Manual[2] 18.4.6.1.7 Isolation Requirements.
Only peripheral that is permitted for dynamic pin mux configuration is
MMC. This is to accommodate the requirements for varied speeds (which
require IO-delay support in kernel as well). Hence with the exception
of MMC, all other pin mux configurations are removed from the dts.
