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

2022-05-13T03:56:06Z

Instead of having FDT reset 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/reset: separate driver init func

2021-11-12T04:46:23Z

lib: sbi: error handling in fdt_reset_init()

2021-11-08T05:20:48Z

The initialization of a reset driver may fail for various reasons, like a PMIC based reset driver not finding the required I2C driver. The return code of the init routine may take other error values than -ENODEV. If the initialization of a reset driver fails, this should not lead to the board hanging. It is enough that the reset driver does not call sbi_system_reset_add_device() to avoid invoking the driver for a device that could not be initialized. Change the return type of fdt_reset_init() to void. Print a message if an error occurs. Signed-off-by: Heinrich Schuchardt Reviewed-by: Dong Du Reviewed-by: Anup Patel

include: sbi_utils: Introduce an helper to get fdt base address

2021-11-02T05:53:16Z

This simply adds an helper to get fdt address which is more explicit than sbi_scratch_thishart_arg1_ptr. Signed-off-by: Alexandre Ghiti Reviewed-by: Xiang W Reviewed-by: Anup Patel

lib: utils/reset: Add a sunxi watchdog reset driver

2021-09-14T07:54:53Z

One of the watchdogs in the D1 SoC provides a "soft reset" function, which allows software to immediately reset the entire SoC. Add a driver so it can implement the SBI system reset function. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

lib: utils/reset: Sort fdt_reset driver list

2021-09-14T06:43:55Z

In preparation for adding a new fdt_reset driver, ensure the existing lists are sorted alphabetically. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

lib: utils: support both of gpio-poweroff, gpio-reset

2021-07-27T11:56:54Z

The generic GPIO reset driver has two entries in the match table: "gpio-poweroff", "gpio-reset". Only the first entry is considered by fdt_reset_init(). Define "gpio-poweroff" and "gpio-reset" as compatibility strings of two separate reset drivers. They still can share code.
