gpio/starfive: redundant readl() call

2023-10-06T11:59:09Z

In starfive_gpio_direction_output() readl() is called twice to read the gpio direction register. The result of the first read is discarded. Remove the redundant read.

lib: utils/gpio: Fix RV32 compile error for designware GPIO driver

2023-07-12T05:52:03Z

Currently, we see following compile error in the designeware GPIO driver for RV32 systems: lib/utils/gpio/fdt_gpio_designware.c:115:20: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] 115 | chip->dr = (void *)addr + (bank * 0xc); | ^ lib/utils/gpio/fdt_gpio_designware.c:116:21: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] 116 | chip->ext = (void *)addr + (bank * 4) + 0x50; We fix the above error using an explicit type-cast to 'unsigned long'.
