Subject: [PATCH 0/2] serial: 8250_dw: add fractional divisor support
Date: Mon, 2 Jul 2018 18:04:28 +0800 [thread overview]
Message-ID: <20180702180428.331b36c5@xhacker.debian> (raw)
For Synopsys DesignWare 8250 uart which version >= 4.00a, there's a
valid divisor latch fraction register. The fractional divisor width is
4bits ~ 6bits.
patch1 introduces necessary hooks to 8250 core.
patch2 implement the fractional divisor support for Synopsys DW 8250.

serial: 8250: introduce get_divisor() and set_divisor() hook
serial: 8250_dw: add fractional divisor support
