From: Lokesh Vutla Date: Fri, 21 Oct 2016 10:38:33 +0000 (+0530) Subject: ARM: dts: dra72-evm: Remove pinmux configurations for erratum i869 X-Git-Tag: microblaze-4.13-rc1~1035^2~2^2~17 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=46cfc8945887d379630dc7da47c2e546ee65152f;p=linux-2.6-microblaze.git ARM: dts: dra72-evm: Remove pinmux configurations for erratum i869 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] (IO Glitches can occur when changing IO settings) 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 and DCAN. MMC is permitted to change to accommodate the requirements for varied speeds (which require IO-delay support in kernel as well). DCAN is a result of i893[1] (DCAN initialization sequence). With the exception of DCAN and MMC, all other pin mux configurations are removed from the dts.
