Subject: [PATCH 2/2] Add 'sparse16550' support to PowerPC bootwrapper
Date: Sat, 07 Jul 2007 12:57:50 -0400 [thread overview]
Message-ID: <1183827470.3066.73.camel@shinybook.infradead.org> (raw)
In-Reply-To: <200707071410.14998.arnd@arndb.de>
The bootwrapper already handles a 'reg-shift' property on serial ports
and does the right thing. However, these ports really shouldn't be
claiming to be compatible with 'ns16550'. Introduce a new 'sparse16550'
type for them instead.
