lib: utils/reset: Add Andes fdt reset driver support

2022-10-23T04:59:23Z

Add ATCWDT200 as reset device of AE350 platform, this driver requires SMU to program the reset vector registers before triggering WDT software restart signal. dts example: smu@f0100000 { compatible = "andestech,atcsmu"; reg = <0x00000000 0xf0100000 0x00000000 0x00001000>; }; wdt: wdt@f0500000 { compatible = "andestech,atcwdt200"; reg = <0x00000000 0xf0500000 0x00000000 0x00001000>; interrupts = <3 4>; interrupt-parent = <&plic0>; clock-frequency = <15000000>; }; Signed-off-by: Yu Chien Peter Lin Reviewed-by: Leo Yu-Chi Liang Reviewed-by: Anup Patel

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

2022-08-08T04:03:26Z

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

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: 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/reset: Add generic GPIO reset driver

2021-07-17T08:42:07Z

We add generic GPIO reset driver inspired from gpio-restart and gpio-poweroff drivers of Linux kernel. Signed-off-by: Green Wan Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: reset: unify naming of 'sifive_test' device

2021-07-05T16:06:40Z

Unify all the file and function names of 'sifive_test' device, to use the same prefix. This is also a preparatory patch for upcoming sifive reset device. Signed-off-by: Green Wan Reviewed-by: Bin Meng Reviewed-by: Anup Patel

lib: utils: reset: Add T-HEAD sample platform reset driver

2021-04-22T09:43:53Z

This driver is for T-HEAD test chip, fpga. It could work with all T-HEAD riscv processors: C9xx series. example1: (Using io-regs for reset) reset: reset-sample { compatible = "thead,reset-sample"; plic-delegate = <0xff 0xd81ffffc>; entry-reg = <0xff 0xff019050>; entry-cnt = <4>; control-reg = <0xff 0xff015004>; control-val = <0x1c>; csr-copy = <0x7f3 0x7c0 0x7c1 0x7c2 0x7c3 0x7c5 0x7cc>; }; example2: (Using csr-regs for reset) reset: reset-sample { compatible = "thead,reset-sample"; plic-delegate = <0xff 0xd81ffffc>; using-csr-reset; csr-copy = <0x7c0 0x7c1 0x7c2 0x7c3 0x7c5 0x7cc 0x3b0 0x3b1 0x3b2 0x3b3 0x3b4 0x3b5 0x3b6 0x3b7 0x3a0>; }; example3: (Only delegate plic enable to S-mode) reset: reset-sample { compatible = "thead,reset-sample"; plic-delegate = <0xff 0xd81ffffc>; }; After this patch, all T-HEAD c9xx would use platform/generic with fw_dynamic as default: CROSS_COMPILE=riscv64-linux-gnu- PLATFORM=generic FW_PIC=y /usr/bin/make The platform/thead will be deprecated.
