Subject: [PATCH v2 09/11] spi: cadence-qspi: add mobileye,eyeq5-ospi compatible
Date: Fri, 05 Apr 2024 17:02:19 +0200	[thread overview]
Message-ID: <20240405-cdns-qspi-mbly-v2-9-956679866d6d@bootlin.com> (raw)
In-Reply-To: <20240405-cdns-qspi-mbly-v2-0-956679866d6d@bootlin.com>

Declare a new mobileye,eyeq5-ospi compatible. Exploit quirk flags:
detect FIFO depth through SRAMPARTITION register; avoid IRQs during
read operations.
