Hello,
In this version the most notable change is in patch 9, where we left the
tt-atlantis out of the changes being done. The reason is that the board
will have UART related changes soon, and the UART FDT will be most
likely impacted, thus it's better to wait for the DT to stabilize first.
Other change done is the "local phandle" handling. For all helpers that
receives a 'next_phandle' pointer we'll check if the pointer is valid
and use its val as next phandle. Otherwise we'll use
qemu_fdt_alloc_phandle().
Other minor changes were also done following the discussions in v3.
Patches based on alistair/riscv-to-apply.next.
Changes from v3:
- patch 3:
- renamed 'phandle' to 'next_phandle'. If non-null the helper will
use (*next_phandle) as the phandle value for the new subnode.
Otherwise the helper will retrieve a phandle via qemu_fdt_alloc_phandle().
- patch 4:
- added a new 'next_phandle' optional pointer. If non-null the helper
will use (*next_phandle) as the phandle value for the new subnode.
Otherwise the helper will retrieve a phandle via qemu_fdt_alloc_phandle();
- removed the iommu_irq_map array;
- instead of returning 'void' return the DT iommu phandle.
- patch 6:
- renamed 'phandle' to 'next_phandle'. If non-null the helper will
use (*next_phandle) as the phandle value for the new subnode.
Otherwise the helper will retrieve a phandle via qemu_fdt_alloc_phandle().
- patch 7:
- renamed 'phandle' to 'next_phandle'. If non-null the helper will
use (*next_phandle) as the phandle value for the new subnode.
Otherwise the helper will retrieve a phandle via qemu_fdt_alloc_phandle().
- patch 9:
- removed all tt-atlantis.c changes;
- renamed irq_mmio_phandle to irq_phandle;
- removed both bool flags;
- "/chosen" and "/alias" are now set manually by the board;
- a new riscv_fdt_get_uart_nodename() helper were added;
- added an UART_STD_CLOCK_FREQ to hide the magic 3.6864 MHz hardcoded
clock value.
- patch 10:
- renamed irq_mmio_phandle to irq_phandle.
