Subject: [RFC RFT PATCH v1 0/1] ARM: orion5x: convert D-Link DNS-323 to the Device Tree
Date: Wed, 27 Apr 2022 19:21:22 +0300	[thread overview]
Message-ID: <20220427162123.110458-1-maukka@ext.kapsi.fi> (raw)

Hello all,

I am making an attempt to create a device tree for D-Link DNS-323 devices
but I am falling short on a few specific details. I am requesting a
general review of the device tree files. I have access to DNS-323 rev A1
only and the B1 and C1 need to be tested separately, so I am reaching out
to people who might have them. The questions that I have at the moment are
below.

- some of resulting IRQs are different from what was requested in device tree
- logs say NR_IRQS is different from mach file one
- sata_mv fails to initialise with -22 (-EINVAL)
- there is no concensus on how to get ascii formatted MAC address from mtd
  partitions so eth is not fully functional without setting the MAC from
  userspace
- revs B1 and C1 need testing
- how to configure RTC to wake system from sleep?

What currently works in rev A1
 - leds
 - keys
 - fan
 - temperature sensor
 - shutdown
 - reboot
 - mtd partitions
 - ethernet (mac address must be set manually)

I have included relevant parts from boot log to better illustrate what seems
to be off target

-------------------------------- DT log ---------------------------------------
...
NR_IRQS: 16, nr_irqs: 16, preallocated irqs: 16
...
sata_mv 0000:00:01.0: Gen-IIE 32 slots 4 ports SCSI mode IRQ via INTx
sata_mv: probe of 0000:00:01.0 failed with error -22
...
mv64xxx_i2c mv64xxx_i2c.0: can't get pinctrl, bus recovery not supported
...
-------------------------------------------------------------------------------

Best regards,
Mauri
