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

2021-07-17T08:11:17+00:00

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

lib: utils/gpio: Add generic GPIO configuration library

2021-07-17T06:12:51+00:00

We add generic GPIO configuration library which is independent of hardware description format (FDT or ACPI). The OpenSBI platform support or GPIO drivers can register GPIO chip instances which can be discovered and used by different GPIO clients. Each GPIO chip instance has a unique ID which can be used by GPIO clients to lookup GPIO chip instance. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils/fdt: Add fdt_parse_phandle_with_args() API

2021-07-17T06:10:49+00:00

The libfdt project does not have a generic API to parse phandle with args from a DT node so we add fdt_parse_phandle_with_args() for this purpose. This new API will be useful to FDT based drivers. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

utils: fdt: Add fdt helper functions to parse PMU DT nodes

2021-07-11T04:57:57+00:00

The PMU DT node bindings are defined in docs/pmu_support.md Add few fdt helper functions to parse the DT node and update the event-counter mapping tables. Reviewed-by: Anup Patel Signed-off-by: Atish Patra

platform: Replace CLINT library usage with ACLINT library

2021-06-24T04:09:55+00:00

The ACLINT devices are backward compatible with SiFive CLINT so we replace all CLINT library usage in various platforms with ACLINT library. As a result of this replacement, the CLINT library is not used by any part of OpenSBI hence we remove it. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Xiang W

lib: utils: Add FDT parsing API common for both ACLINT and CLINT

2021-06-24T04:09:48+00:00

We add fdt_parse_aclint_node() which can parse both ACLINT and CLINT DT nodes. This means fdt_parse_clint_node() is not required anymore so we remove it as well. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Xiang W

lib: utils/ipi: Add ACLINT MSWI library

2021-06-24T04:09:44+00:00

We add common ACLINT MSWI library similar to the CLINT library so that OpenSBI platforms can use it. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Xiang W

lib: utils/timer: Add ACLINT MTIMER library

2021-06-24T04:08:47+00:00

We add common ACLINT MTIMER library similar to the CLINT library so that OpenSBI platforms can use it. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Xiang W

lib: utils/serial: Add support for Gaisler APBUART

2021-05-06T08:51:07+00:00

This patch adds support for the UART used by the NOEL-V processor. Cobham Gaisler's NOEL-V RISC-V processor IP is available under GPL and commercial license and is described in more detail at https://www.gaisler.com/noelv.

lib: sbi: Simplify system reset platform operations

2021-04-28T11:55:00+00:00

Instead of having system_reset_check() and system_reset() callbacks in platform operations, it will be much simpler for reset driver to directly register these operations as a device to the sbi_system implementation. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis
