Hi guys, here's a series of cleanup patches to the OMAP serial driver. A later series could be made re-implementing DMA using the DMA Engine API. Note that for RX DMA we could be using RX Timeout IRQ as a hint that we better use PIO instead ;-) All patches were tested on my pandaboard, but I'd really like to receive Tested-by on other platforms. After this goes in, I'll probably try to get UART wakeup working again and only after that look at DMA. Changes since v1: . improved commit log on patch 9/13 (formerly 10/13) . removed patch 2/13 . added a new patch switching from spin_lock_irqsave() to spin_lock and spin_unlock_irqrestore to spin_unlock Retested with my pandaboard, UART continues to work: # grep -i uart /proc/interrupts 106: 124 0 GIC OMAP UART2 # grep -i uart /proc/interrupts 106: 189 0 GIC OMAP UART2 # grep -i uart /proc/interrupts 106: 255 0 GIC OMAP UART2 # grep -i uart /proc/interrupts 106: 321 0 GIC OMAP UART2 # grep -i uart /proc/interrupts 106: 387 0 GIC OMAP UART2 # grep -i uart /proc/interrupts 106: 453 0 GIC OMAP UART2 # grep -i uart /proc/interrupts 106: 519 0 GIC OMAP UART2 cheers ps: if anyone knows a better test for UART, let me know. for convenience of anyone testing, patches are available on my git tree [1] on branch uart [1] git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git uart Felipe Balbi (13): serial: omap: define and use to_uart_omap_port() serial: omap: define helpers for pdata function pointers serial: omap: don't access the platform_device serial: omap: drop DMA support serial: add OMAP-specific defines serial: omap: simplify IRQ handling serial: omap: refactor receive_chars() into rdi/rlsi handlers serial: omap: move THRE check to transmit_chars() serial: omap: stick to put_autosuspend serial: omap: set dev->drvdata before enabling pm_runtime serial: omap: drop unnecessary check from remove serial: omap: make sure to suspend device before remove serial: omap: don't save IRQ flags on hardirq arch/arm/mach-omap2/serial.c | 15 +- arch/arm/plat-omap/include/plat/omap-serial.h | 12 +- drivers/tty/serial/omap-serial.c | 713 +++++++++----------------- include/linux/serial_reg.h | 4 + 4 files changed, 254 insertions(+), 490 deletions(-) -- 1.7.12.rc3 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
