H A D | gpio-uniphier.c | c5fb1c25 Fri Oct 13 05:21:51 CDT 2017 Masahiro Yamada <yamada.masahiro@socionext.com> gpio: uniphier: rework single device node model First, I implemented this driver as per-bank model, but it was a design mistake. - There are 31 banks in the maximum case. It is painful to add so many nodes to DT. - The IRQ control registers are shared between banks. Per-bank design is a problem for Linux. The counterpart for Linux turned around to the single node model. Rework based on the driver for Linux. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
