Subject: [PATCH v7 02/17] spi: airoha: remove unnecessary restriction length
Date: Fri, 10 Oct 2025 06:31:21 +0300 [thread overview]
Message-ID: <20251010033136.1475673-3-mikhail.kshevetskiy@iopsys.eu> (raw)
In-Reply-To: <20251010033136.1475673-1-mikhail.kshevetskiy@iopsys.eu>
The "length < 160" restriction is not needed because airoha_snand_write_data()
and airoha_snand_read_data() will properly handle data transfers above
SPI_MAX_TRANSFER_SIZE.
