Subject: [PATCH 5/6] Revert "spi: Raise limit on number of chip selects"
Date: Sat, 12 Oct 2024 11:53:39 +0200 [thread overview]
Message-ID: <20241012-spi_multi_cs_cleanup-v1-5-dc491113880d@gmail.com> (raw)
In-Reply-To: <20241012-spi_multi_cs_cleanup-v1-0-dc491113880d@gmail.com>
Now that we removed the limit of chip selects for the controller, we can
reduce the amount of chip selects per device again to its original
value.
This reverts commit 2f8c7c3715f2c6fb51a4ecc0905c04dd78a3da29.
