Subject: [PATCH 0/2] tty: serial: OMAP: work around broken driver, IP block
Date: Sat, 21 Jan 2012 00:27:37 -0700 [thread overview]
Message-ID: <20120121071934.18707.64258.stgit@dusk> (raw)
[ 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.
