From mboxrd@z Thu Jan 1 00:00:00 1970 From: paul@pwsan.com (Paul Walmsley) Date: Sat, 21 Jan 2012 00:27:37 -0700 Subject: [PATCH 0/2] tty: serial: OMAP: work around broken driver, IP block Message-ID: <20120121071934.18707.64258.stgit@dusk> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org [ This series is targeted for merging during v3.3-rc ] On v3.3-rc1, the OMAP serial console doesn't behave properly when power management is enabled (the default with omap2plus_defconfig). This seems to be due to a combination of a silicon bug in the UART IP block and broken FIFO settings in the OMAP serial driver. This patch series attempts to work around these problems. The workarounds are not perfect; see the patch descriptions for more details. Tested on OMAP3530 BeagleBoard. This series will need to be tested on OMAP2 and OMAP4 before it is ready to merge. - Paul --- Paul Walmsley (2): tty: serial: OMAP: ensure FIFO levels are set correctly in non-DMA mode tty: serial: OMAP: transmit FIFO threshold interrupts don't wake the chip arch/arm/plat-omap/include/plat/omap-serial.h | 1 drivers/tty/serial/omap-serial.c | 86 ++++++++++++++++++++++++- 2 files changed, 82 insertions(+), 5 deletions(-)
