ARM: OMAP2+: critical DRA7xx fix for v4.5-rc
Force the DRA7xx Ethernet internal clock source to stay enabled
per TI erratum i877:
http://www.ti.com/lit/er/sprz429h/sprz429h.pdf
Otherwise, if the Ethernet internal clock source is disabled, the
chip will age prematurely, and the RGMII I/O timing will soon
fail to meet the delay time and skew specifications for 1000Mbps
Ethernet.
This fix should go in as soon as possible.
Basic build, boot, and PM test results are available here:
