GPIO: CREG: improve flexibility of hsdk-creg-gpio driver

2018-07-31T04:49:47Z

CREG GPIO is a driver for weird soc-specific output ports, which are controlled by some fields in memory mapped register. Example: 31 9 7 5 0 < bit number | | | | | [ not used | gpio-1 | gpio-0 | <-shift-> ] < 32 bit register ^ ^ | | write 0x2 == set output to "1" (activate) write 0x3 == set output to "0" (deactivate) As of tooday we only support fixed (hardcoded) bit per gpio line, activate / deactivatei and shift values. Fix that by read them from device tree to be able to use this driver for other boards. Remove "hsdk" prefix from compatible string as this driver can be used with different boards like HSDK, AXS101, AXS103, etc. Signed-off-by: Eugeniy Paltsev Signed-off-by: Alexey Brodkin

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini
