Commit Message

Swee, Leong Ching Dec. 22, 2023, 5:44 a.m. UTC
From: Swee Leong Ching <leong.ching.swee@intel.com>

There is no support for per DMA channel interrupt for non-MSI platform,
where the MAC's per channel interrupt hooks up to interrupt controller(GIC)
through shared peripheral interrupt(SPI) to handle interrupt from TX/RX
transmit channel.

This patch generalize the existing MSI ISR to also support non-MSI
platform.

stmmac_get_platform_resources() populate stmmac_resources struct, and the checking is on stmmac_request_irq_multi()
 so add 2 array to store the irq error instead?
