Subject: [PATCH v3 14/14] serial: 8250_uniphier: Switch to use uart_read_port_properties()
Date: Mon,  4 Mar 2024 14:27:15 +0200	[thread overview]
Message-ID: <20240304123035.758700-15-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20240304123035.758700-1-andriy.shevchenko@linux.intel.com>

Since we have now a common helper to read port properties
use it instead of sparse home grown solution.
