This patch add support for rockchip gpio controller, which is supported in pinctrl driver in the past. With this patch, the pinctrl-rockchip driver will drop gpio related codes and populate platform driver to gpio-rockchip. Signed-off-by:

In the past we only need on clock which name "pclk" for a gpio controller. In the new version gpio controller, there add some register to change debounce clock dynamic, so the dt node needs to add the second clock, we call it "dbclk". The clock property need 2 items on some rockchip chips such as RK3568 SoCs. Signed-off-by:

- Add support for partitionned EPPIs, modeled after the existing partitioned PPI support * irq/gicv3-eppi-partition: irqchip/gic-v3: Fix selection of partition domain for EPPIs irqchip/gic-v3: Add __gic_get_ppi_index() to find the PPI number from hwirq Signed-off-by: -
James Morse authored
commit 5f51f803 ("irqchip/gic-v3: Add EPPI range support") added GIC_IRQ_TYPE_PARTITION support for EPPI to gic_irq_domain_translate(), and commit 52085d3f ("irqchip/gic-v3: Dynamically allocate PPI partition descriptors") made the gic_data.ppi_descs array big enough for EPPI, but neither gic_irq_domain_select() nor partition_domain_translate() were updated. This means partitions are created by partition_create_desc() for the EPPI range, but can't be registered as they will always match the root domain and map to the summary interrupt. Update gic_irq_domain_select() to match PPI and EPPI. The fwspec for PPI and EPPI both start from 0. Use gic_irq_domain_translate() to find the hwirq from the fwspec, then convert this to a ppi index. Reported-by:

gic_get_ppi_index() is a useful concept for ppi partitions, as the GIC has two PPI ranges but needs mapping to a single range when used as an index in the gic_data.ppi_descs[] array. Add a double-underscore version which takes just the intid. This will be used in the partition domain select and translate helpers to enable partition support for the EPPI range. Signed-off-by:
