[PATCH 0/5] tty/serial: at91: fix atmel_serial_probe(), dma_sync_* and the Hardware Handshaking support

From: Cyrille Pitchen
Date: Tue Dec 09 2014 - 08:31:44 EST


This series of patches fix many bugs:
- a wrong enum type was used when calling dma_sync_*_for_cpu() and
dma_sync_*_for_device()
- IO accesses to registers were done in atmel_serial_probe() after the
peripheral clock had been disabled.
- the -EDEFER error was not handled properly in atmel_serial_probe()
- the Hardware Handshaking mode could never be enabled to control the RTS line

The patches were made from the next-20141205 tag of the linux-next repository.
They were tested on a SAMA5Dx FPGA platform.

Cyrille Pitchen (5):
tty/serial: at91: use correct type for dma_sync_*_for_cpu() and
dma_sync_*_for_device()
tty/serial: at91: enable peripheral clock before accessing I/O
registers
tty/serial: at91: fix error handling in atmel_serial_probe()
tty/serial: at91: fix RTS line management when hardware handshake is
enabled
tty/serial: at91: fix typo and indentation
