Subject: [PATCH v6 0/2] PCI: mediatek: Fixups for the IRQ handle routine and MT7622's class code

From: Honghui Zhang <honghui.zhang@...iatek.com>

Two fixups for mediatek's host bridge:
The first patch fixup class type and vendor ID for MT7622.
The second patch fixup the IRQ handle routine by using irq_chip solution
to avoid IRQ reentry which may exist for both MT2712 and MT7622.

Change since v5:
 - Make the comments consistend with the code modification in the first patch.
 - Using writew to performing a 16-bit write.
 - Using irq_chip solution to fix the IRQ issue.

The v5 patchset could be found in:
 https://patchwork.kernel.org/patch/10133303
 https://patchwork.kernel.org/patch/10133305

Change since v4:
 - Only setup vendor ID for MT7622, igorning the device ID since mediatek's
   host bridge driver does not cares about the device ID.

Change since v3:
 - Setup the class type and vendor ID at the beginning of startup instead
   of in a quirk.
 - Add mediatek's vendor ID, it could be found in:
   https://pcisig.com/membership/member-companies?combine=&page=4

Change since v2:
 - Move the initialize of the iterate before the loop to fix an
   INTx IRQ issue in the first patch

Change since v1:
 - Add the second patch.
 - Make the first patch's commit message more standard.
Honghui Zhang (2):
  PCI: mediatek: Set up vendor ID and class type for MT7622
  PCI: mediatek: Using chained IRQ to setup IRQ handle
