serial8250: DLL/DLM rework, Emma Mobile UART driver [PATCH 01/06] serial8250: Add dl_read()/dl_write() callbacks [PATCH 02/06] serial8250: Use dl_read()/dl_write() on Alchemy [PATCH 03/06] serial8250: Use dl_read()/dl_write() on RM9K [PATCH 04/06] serial8250: Clean up default map and dl code [PATCH 05/06] serial8250: Introduce serial8250_register_8250_port() [PATCH 06/06] serial8250-em: Add Emma Mobile UART driver This series cleans up and adjusts the 8250 code base to allow hooking in a driver for the UART in Emma Mobile SoCs. In short: - Patch 1-4 tie in 8250-specific dl_read()/dl_write() callbacks. - Patch 5 adds a new register function to use new callbacks. - Patch 6 adds a new driver that makes use of the above. I'd be happy to rework the above patches if needed. The main challenge for Emma Mobile UART support is the non- standard offsets for DLL and DLM registers. Note that there is no DT support included at this point, but it boils down to a 10 line change. The boot loader on my board does not do DT so I'd like to use kexec for DT development (as usual), but to use kexec I first need to get a non-DT kernel working. Which is basically this. =) Signed-off-by: Magnus Damm <damm@xxxxxxxxxxxxx> --- Builds on top of linux-next 20120501. drivers/tty/serial/8250/8250.c | 373 ++++++++++++++++++------------------- drivers/tty/serial/8250/8250.h | 14 + drivers/tty/serial/8250/8250_em.c | 179 +++++++++++++++++ drivers/tty/serial/8250/Kconfig | 8 drivers/tty/serial/8250/Makefile | 1 include/linux/serial_8250.h | 1 6 files changed, 392 insertions(+), 184 deletions(-) -- 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
