From mboxrd@z Thu Jan 1 00:00:00 1970 From: jorge.ramirez-ortiz@linaro.org (Jorge Ramirez-Ortiz) Date: Mon, 23 Feb 2015 22:46:52 -0500 Subject: [PATCH v2] drivers/tty: amba-pl011: defer driver probing if external dma is not ready In-Reply-To: References: Message-ID: <1424749613-24765-1-git-send-email-jorge.ramirez-ortiz@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The previous version of this patch, as Rob Herring pointed out, broke implementations using platform data rather that DT for resolving the DMA channel allocation. This is now being taken care of by enqueing dma probe requests for those platforms instead of attempting the probe - deferred driver probe is only functional for OF and ACPI platforms. drivers/tty/serial/amba-pl011.c | 67 +++++++++++++++++++++++++++++++++++++++++++------------------------ 1 file changed, 43 insertions(+), 24 deletions(-) thanks, Jorge
