lan78xx_link_reset explicitly clears the MAC's view of the PHY's IRQ status. In doing so it potentially leaves the PHY with a pending interrupt that will never be acknowledged, at which point no further interrupts will be generated. Avoid the problem by acknowledging any pending PHY interrupt after clearing the MAC's status bit. See: raspberrypi#2937 Signed-off-by: Phil Elwell <phil@raspberrypi.com>
For applications of the LAN78xx that don't have valid programmed EEPROMs or OTPs, enabling both LEDs and auto-negotiation by default seems reasonable. Signed-off-by: Phil Elwell <phil@raspberrypi.org>
Add two new DT properties:
* microchip,eee-enabled - a boolean to enable EEE
* microchip,tx-lpi-timer - time in microseconds to wait before entering
low power state

Disabling tx_lpi or eee should not cause the value of tx_lpi_timer to be lost, even though it is not useful until they are re-enabled. Signed-off-by: Phil Elwell <phil@raspberrypi.com>
Apparently some NVMe SSD implementations don't fall back to MSI cleanly, instead making the driver allocate one queue via the legacy interrupt. There are still only 32 vectors available, but should be sufficient for the majority of use-cases on BCM2711. Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>

Drop from RGB to YUV422 output if RGB couldn't be supported within the defined max_bpc and TMDS rates, and then try dropping max_bpc. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>

The upstream version of the RP1 clock driver is not ready for us to use it. Signed-off-by: Phil Elwell <phil@raspberrypi.com>

While we continue to use the downstream RP1 driver, update some other Kconfig settings to recognise MFD_RP1 as a valid RP1 driver. Signed-off-by: Phil Elwell <phil@raspberrypi.com>
Replace MISC_RP1 with MFD_RP1, rebuilding the defconfigs to match. Signed-off-by: Phil Elwell <phil@raspberrypi.com>

This worked for me: I'll merge this now, and the "upstream" rp1 support can come on top. |

This PR builds on #7002, adding in sufficient extra patches to make Pi 5 usable along with a few other forward ports where the merges were non-trivial.
My approach to the recent upstream RP1 commits has been to revert or partially undo them and restore the downstream equivalent, the aim being to get something working ASAP. We can then work on more refined downstream changes, with a view to using them instead at a later date.
