| * | Fix problems with GPIO usage | Benjamin Herrenschmidt | 2018-06-07 | 1 | -3/+6 |
| | | | | | | | | | | | | | | | | | | The "value" register doesn't return the last data written when read but returns the value sampled on the line, which may or may not be the value written for an output GPIO. For example it can be delayed by the synchronizers. So whenever the CF reads the value to adjust its caches it needs to use the "data read" register intead, otherwise it can clobber values set by Linux when doing handshaking. Also don't use %d0 for DTRA, use %d1 to avoid interrupts clobber and do read/modify/write cycles on it as it's not a permanent cached value, just a temporary.
