This series is a set of patches which were originally part of RFC v1 series [1] to add ACPI support in RISC-V interrupt controllers. Since these patches are independent of the interrupt controllers, creating this new series which helps to merge instead of waiting for big series. This set of patches primarily adds support below ECR [2] which is approved by the ASWG and adds below features. - Get CBO block sizes from RHCT on ACPI based systems. - Set timer_can_not_wakeup in timer driver based on the flag in RHCT. Additionally, the series contains a patch to improve acpi_os_ioremap().
