Subject: [PATCH v2 11/12] serial: 8250_lpss: Use 32-bit reads
Date: Mon,  4 Apr 2022 11:29:11 +0300	[thread overview]
Message-ID: <20220404082912.6885-12-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20220404082912.6885-1-ilpo.jarvinen@linux.intel.com>

Use 32-bit reads in order to not lose higher bits of DW
UART regs.
