2024-03-20	ACPI: RISC-V: Add CPPC driver	Sunil V L	2	-0/+158
	Add cpufreq driver based on ACPI CPPC for RISC-V. The driver uses either SBI CPPC interfaces or the CSRs to access the CPPC registers as defined by the RISC-V FFH spec.

2023-10-26	RISC-V: ACPI: RHCT: Add function to get CBO block sizes	Sunil V L	1	-0/+87
	Cache Block Operation (CBO) related block size in ACPI is provided by RHCT. Add support to read the CMO node in RHCT to get this information.

2023-10-26	RISC-V: ACPI: Update the return value of acpi_get_rhct()	Sunil V L	1	-3/+3
	acpi_get_rhct() currently returns pointer to acpi_table_header structure. But since this is specific to RHCT, return pointer to acpi_table_rhct structure itself.

2023-06-01	drivers/acpi: RISC-V: Add RHCT related code	Sunil V L	2	-0/+85
	RHCT is a new table defined for RISC-V to communicate the features of the CPU to the OS. Create a new architecture folder in drivers/acpi and add RHCT parsing code.
