2018-06-28staging: rtsx: remove rtsx_trace() and related codeArnd Bergmann1-1/+0
The driver has rather excessive amount of tracing code, which would be better done using ftrace. This is obviously not a main feature of the driver, and it should work just as well without it. Removing it saves over 1300 lines of code and likely makes the driver a bit faster by avoiding lots of calls into the timekeeping code. I came across this while cleaning up the last users of the deprecated getnstimeofday64() function, of which there is one in the now-removed get_current_time() function of the rtsx driver that was only used for tracing.

2013-11-25staging: rts5208: add support for rts5208 and rts5288Micky Ching1-0/+769
There are still many rts5208/5288 card readers being used, but no drivers are supported them in kernel now. This driver can make a great convenience for people who use them. Many other rts-series card reader are supported by mfd driver, but due to much difference with others, rts5208/5288 can not add into mfd driver pretty now, so we provide a separated driver here to support the device.
