Subject: [PATCH v3 0/3] serial: 8250_dw: Introduce SG2044 uart support.

SG2044 relys on an internal divisor when calculating bitrate, which
means a wrong clock for the most common bitrates. So a quirk is needed
for this uart device to skip the set rate call and only relys on the
internal UART divisor.


Changed from v1:
1. patch 1: improve the bindings commit message.
2. patch 2: rename jh7100 quirk and rename the quirk to
            dw8250_skip_set_rate_data.

Changed from v2:
1. patch 1: add a new patch to merge the vendor specific compatibles
2. patch 2: adopt the new patch.

Inochi Amaoto (3):
  dt-bindings: serial: snps,dw-apb-uart: merge duplicate compatible
    entry.
  dt-bindings: serial: snps-dw-apb-uart: Add Sophgo SG2044 uarts
  serial: 8250_dw: Add Sophgo SG2044 quirk
