lib: utils/gpio: Use heap in SiFive and StartFive GPIO drivers

2023-06-05T10:25:29Z

Let's use heap allocation in SiFive and Starfive GPIO drivers instead of using a fixed size global array. Signed-off-by: Anup Patel Reviewed-by: Andrew Jones

gpio/starfive: add gpio driver and support gpio reset

2023-03-01T03:29:33Z

Add gpio driver and gpio reset function in Starfive JH7110 SOC platform. Signed-off-by: minda.chen Reviewed-by: Anup Patel

lib: utils/fdt: Use kconfig for enabling/disabling

2022-08-08T04:04:08Z

We update FDT support makefile to use kconfig for enabling/disabling. To avoid compilation errors, we also enable FDT for each platform. Signed-off-by: Anup Patel Tested-by: Andrew Jones Acked-by: Atish Patra Tested-by: Atish Patra

lib: utils/gpio: Use kconfig for enabling/disabling drivers

2022-08-08T04:04:02Z

We update gpio drivers makefile to use kconfig for enabling/disabling drivers. To avoid compile errors, we also enable appropriate gpio drivers for each platform. Signed-off-by: Anup Patel Tested-by: Andrew Jones Acked-by: Atish Patra Tested-by: Atish Patra

lib: utils/gpio: Generate FDT gpio driver list at compile-time

2022-05-13T03:57:12Z

Instead of having FDT gpio driver list hard-coded in the C source, we generate it using carray.sh at compile-time. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils/gpio: use list for drivers

2021-11-03T10:27:56Z

Convert static array to sbi_list. This removes size limitation, makes add/remove more efficient and saves space. Signed-off-by: Nikita Shubin Reviewed-by: Anup Patel

lib: utils: Extend fdt_get_node_addr_size() for multiple register sets

2021-08-14T03:32:36Z

We add "index" parameter to fdt_get_node_addr_size() API so that calling function can specify index of desired register set. This will allow fdt_get_node_addr_size() to handle DT nodes with multiple register sets. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils/fdt: Change addr and size to uint64_t

2021-08-07T11:56:51Z

The maximum address and size encoded in DT are 64-bit numbers, so we should use uint64_t for 'addr' and 'size' in fdt_get_node_addr_size(). Signed-off-by: Bin Meng Reviewed-by: Anup Patel

lib: utils/gpio: Add minimal SiFive GPIO driver

2021-07-17T08:26:42Z

We add a minimal SiFive GPIO driver so that we can do GPIO based system power-off and reset. Signed-off-by: Green Wan Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils/gpio: Add simple FDT based GPIO framework

2021-07-17T08:11:17Z

We add a simple FDT based GPIO framework which is built on top of generic GPIO library. The phandle of FDT GPIO chip DT node is treated as unique GPIO chip ID required by the generic GPIO library. The FDT based GPIO chip drivers will be probed on-demand from fdt_gpio_pin_get() called by the GPIO client drivers. Signed-off-by: Anup Patel Reviewed-by: Atish Patra
