Add support for the pin-controller found on the Exynos8895 SoC used in Samsung Galaxy S8 and S8 Plus phones. It has a newly applied pinctrl register layer for FSYS0 with a different bank type offset that consists of the following bit fields: CON: 4, DAT: 1, PUD: 2, DRV: 3, CONPDN: 2, PUDPDN: 2 Signed-off-by: Ivaylo Ivanov <ivo.ivanov.ivanov1@gmail.com> ---Other than minor comments below, LGTM: Reviewed-by: Sam Protsenko <semen.protsenko@linaro.org>
Thanks for the review! Will fix the issues in the following series. Sincerely, Ivaylo
