Semi Nemo boards [1] after the commit "of/irq: Factor out parsing of interrupt-map parent phandle+args from of_irq_parse_raw()" [2]. Error messages: ata2.00: failed to IDENTIFY (I/O error, err_mask=0x4) ata2.00: qc timeout after 10000 mssecs (cmd 0xec) Screenshots [3] I bisected yesterday [4] and "of/irq: Factor out parsing of interrupt-map parent phandle+args from of_irq_parse_raw()" [2] is the first bad commit. Then I created a patch for reverting this first bad commit. I also reverted the changes in drivers/of/property.c. [5] The patched kernel boots with successful detection of the ATA devices. Please check the of/irq updates.
