[PATCH 8/8] ARM: dts: aspeed: Clean up UART nodes

Joel Stanley joel at jms.id.au
Thu Sep 28 17:51:49 AEST 2017


 - Shorten size of reg property so it covers only the implemented
 registers

 - Add VUART compatible

 - Move stray uart1 in g5 definition

 - Remove outdated current-speed property. Different bootloaders use
 different speeds, so this is no longer helpful
