From 3c4549771dd0352e893a0bc9d2344cd8ecd8033d Mon Sep 17 00:00:00 2001 From: Johan Jonker Date: Sun, 19 Mar 2023 16:02:18 +0100 Subject: [PATCH] rockchip: gpio: rk_gpio: use ROCKCHIP_GPIOS_PER_BANK as divider The current divider to calculate the bank ID can change. Given the Rockchip TRM not all gpio-banks have 32 pins per bank. The "gpio-ranges" syntax allows multiple items with variable number of pins. Use a constant ROCKCHIP_GPIOS_PER_BANK as fixed divider.
