This patch adds a DM based driver model for gpio controller present in FU540-C000 SoC on HiFive Unleashed A00 board. This SoC has one GPIO bank and 16 GPIO lines in total, out of which GPIO0 to GPIO9 and GPIO15 are routed to the J1 header on the board. This implementation is ported from linux based gpio driver submitted for review by Wesley W. Terpstra <wesley@sifive.com> and/or Atish Patra <atish.patra@wdc.com> (many thanks !!). The linux driver can be referred here [1] [1]: https://lkml.org/lkml/2018/10/9/1103 Signed-off-by: Sagar Shrikant Kadam <sagar.kadam@sifive.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
