Subject: [PATCH v3 0/4] spi: cadence-qspi: Fix runtime PM and system-wide
suspend
Hi,
This fixes runtime PM and system-wide suspend for the cadence-qspi
driver. Seeing how runtime PM and autosuspend are enabled by default, I
believe this affects all users of the driver.
This series has been tested on both Mobileye EyeQ5 hardware and the TI
J7200 EVM board, under s2idle.
Thanks all,
Théo
