lib: serial: Cadence: Enable compatibility for cdns,uart-r1p8

2023-03-09T15:42:35+00:00

The Cadence driver does not use the RX byte status feature and hence can be advertised to be compatible with cdns,uart-r1p8 as well. Signed-off-by: Mayuresh Chitale Reviewed-by: Anup Patel

lib: utils/i2c: Add minimal StarFive jh7110 I2C driver

lib: sbi: Add system_suspend_allowed domain property

2023-02-27T14:15:28+00:00

Only privileged domains should be allowed to suspend the entire system. Give the root domain this property by default and allow other domains to be given the property by specifying it in the DT. Signed-off-by: Andrew Jones Reviewed-by: Anup Patel

lib: utils/fdt/fdt_domain: Simplify region access permission check

2023-02-27T08:19:21+00:00

The region access permission check in __fdt_parse_region() can be simplified as masking SBI_DOMAIN_MEMREGION_{M,SU}_ACCESS_MASK is enough. While we are here, update the confusing comments to match the codes. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

include: types: Add typedefs for endianness

2023-02-08T12:54:13+00:00

If any variable/memory-location follows certain endianness then its important to annotate it properly so that proper conversion can be done before read/write from that variable/memory. Also, use these new typedefs in libfdt_env.h for deriving its own custom fdtX_t types Signed-off-by: Rahul Pathak Reviewed-by: Anup Patel

lib: utils/fdt: Use byteorder conversion functions in libfdt_env.h

2023-02-08T12:47:42+00:00

FDT follows big-endian and CPU can be little or big endian as per the implementation. libfdt_env.h defines function for conversion between fdt and cpu byteorder according to the endianness. Currently, libfdt_env.h defines custom byte swapping macros and then undefines them. Instead, use the generic endianness conversion functions Signed-off-by: Rahul Pathak Reviewed-by: Xiang W Reviewed-by: Anup Patel
