This series fixes and enables PCIe and NVMe support on RK3568.
Patch 1 adds a dev_read_addr_size_index_ptr function. Patch 2-3 fixes main issue in the driver to be usable on RK3568. Patch 4 fixes a long wait time during probe when no device is attached. Patch 5 hides BARs of the root complex that could claim the entire memory region during PCI autoconfig. Patch 6 adds support for the gpios prop to the fixed regulators driver. Patch 7 adds a missing clock to the clock driver. Patch 8 enables PCIe and NVMe support on rk3568-rock-3a. Patch 9 updates the device tree with new reg and ranges values.
For a clean apply of patch 8, the series at [1] may be needed.
I have tested that a Samsung 970 EVO NVMe is detected on a ROCK 3A,

and I have also verified that the network controller continues to be detected on a ROCK 5B.

Changes in v2: - Rebased on custodians/u-boot-rockchip master branch and the defconfig and spi v2 series at [1]. - Drop dependency on basic reference counting of gpio regulators series, pcie2x1 is disabled for rk3568-rock-3a to avoid a system freeze due to disable of a shared vpcie3v3-supply regulator while in use by pcie3x2. - Add and use dev_read_addr_size_index_ptr function. - Update commit messages. - Collect r-b tags.
