This patch fixes bug on gpio drive strength helper function.
The offset should be like follwoing.
- off = chip->chip.base - pin;
+ off = pin - chip->chip.base;
In the s5p_gpio_get_drvstr(),
the second line is unnecessary, because overwrite drvstr.
drvstr = __raw_readl(reg);
- drvstr = 0xffff & (0x3 << shift);
And need 2bit masking before return the drvstr value.
drvstr = drvstr >> shift;
+ drvstr &= 0x3;
In the s5p_gpio_set_drvstr(), need relevant bit clear.
tmp = __raw_readl(reg);
+ tmp &= ~(0x3 << shift);
tmp |= drvstr << shift;
